contents.</p>
<p>A QDir is used to manipulate path names, access information
regarding paths and files, and manipulate the underlying file
system. It can also be used to access Qt's <a href="resources.html#resource-system">resource system</a>.</p>
<p>Qt uses "/" as a universal directory separator in the same way
that "/" is used as a path separator in URLs. If you always use "/"
as a directory separator, Qt will translate your paths to conform
to the underlying operating system.</p>
<p>A QDir can point to a file using either a relative or an
absolute path. Absolute paths begin with the directory separator
(optionally preceded by a drive specification under Windows).
Relative file names begin with a directory name or a file name and
specify a path relative to the current directory.</p>
<p>Examples of absolute paths:</p>
<pre class="cpp">
<span class="type">QDir</span>(<span class="string">"/home/user/Documents"</span>)
<span class="type">QDir</span>(<span class="string">"C:/Documents and Settings"</span>)
</pre>
<p>On Windows, the second example above will be translated to
<tt>C:\Documents and Settings</tt> when used to access files.</p>
<p>Examples of relative paths:</p>
<pre class="cpp">
<span class="type">QDir</span>(<span class="string">"images/landscape.png"</span>)
</pre>
<p>You can use the <a href="qdir.html#isRelative">isRelative</a>()
or <a href="qdir.html#isAbsolute">isAbsolute</a>() functions to
check if a QDir is using a relative or an absolute file path. Call
<a href="qdir.html#makeAbsolute">makeAbsolute</a>() to convert a
relative QDir to an absolute one.</p>
<a id="navigation-and-directory-operations" name="navigation-and-directory-operations" />
<h3>Navigation and Directory Operations</h3>
<p>A directory's path can be obtained with the <a href="qdir.html#pathx">path</a>() function, and a new path set with the
<a href="qdir.html#setPath">setPath</a>() function. The absolute
path to a directory is found by calling <a href="qdir.html#absolutePath">absolutePath</a>().</p>
<p>The name of a directory is found using the <a href="qdir.html#dirName">dirName</a>() function. This typically returns
the last element in the absolute path that specifies the location
of the directory. However, it can also return "." if the QDir
represents the current directory.</p>
<pre class="cpp">
<span class="type">QDir</span>(<span class="string">"Documents/Letters/Applications"</span>)<span class="operator">.</span>dirName() <span class="comment">// "Applications"</span>
<span class="type">QDir</span>()<span class="operator">.</span>dirName() <span class="comment">// "."</span>
</pre>
<p>The path for a directory can also be changed with the <a href="qdir.html#cd">cd</a>() and <a href="qdir.html#cdUp">cdUp</a>()
functions, both of which operate like familiar shell commands. When
<a href="qdir.html#cd">cd</a>() is called with the name of an
existing directory, the QDir object changes directory so that it
represents that directory instead. The <a href="qdir.html#cdUp">cdUp</a>() function changes the directory of the
QDir object so that it refers to its parent directory; i.e.
cd("..") is equivalent to <a href="qdir.html#cdUp">cdUp</a>().</p>
<p>Directories can be created with <a href="qdir.html#mkdir">mkdir</a>(), renamed with <a href="qdir.html#rename">rename</a>(), and removed with <a href="qdir.html#rmdir">rmdir</a>().</p>
<p>You can test for the presence of a directory with a given name
by using <a href="qdir.html#exists">exists</a>(), and the
properties of a directory can be tested with <a href="qdir.html#isReadable">isReadable</a>(), <a href="qdir.html#isAbsolute">isAbsolute</a>(), <a href="qdir.html#isRelative">isRelative</a>(), and <a href="qdir.html#isRoot">isRoot</a>().</p>
<p>The <a href="qdir.html#refresh">refresh</a>() function re-reads
the directory's data from disk.</p>
<a id="files-and-directory-contents" name="files-and-directory-contents" />
<h3>Files and Directory Contents</h3>
<p>Directories contain a number of entries, representing files,
directories, and symbolic links. The number of entries in a
directory is returned by <a href="qdir.html#count">count</a>(). A
string list of the names of all the entries in a directory can be
obtained with <a href="qdir.html#entryList">entryList</a>(). If you
need information about each entry, use <a href="qdir.html#entryInfoList">entryInfoList</a>() to obtain a list of
<a href="qfileinfo.html">QFileInfo</a> objects.</p>
<p>Paths to files and directories within a directory can be
constructed using <a href="qdir.html#filePath">filePath</a>() and
<a href="qdir.html#absoluteFilePath">absoluteFilePath</a>(). The
<a href="qdir.html#filePath">filePath</a>() function returns a path
to the specified file or directory relative to the path of the QDir
object; <a href="qdir.html#absoluteFilePath">absoluteFilePath</a>()
returns an absolute path to the specified file or directory.
Neither of these functions checks for the existence of files or
directory; they only construct paths.</p>
<pre class="cpp">
<span class="type">QDir</span> directory(<span class="string">"Documents/Letters"</span>);
<span class="type"><a href="qstring.html">QString</a></span> path <span class="operator">=</span> directory<span class="operator">.</span>filePath(<span class="string">"contents.txt"</span>);
<span class="type"><a href="qstring.html">QString</a></span> absolutePath <span class="operator">=</span> directory<span class="operator">.</span>absoluteFilePath(<span class="string">"contents.txt"</span>);
</pre>
<p>Files can be removed by using the <a href="qdir.html#remove">remove</a>() function. Directories cannot be
removed in the same way as files; use <a href="qdir.html#rmdir">rmdir</a>() to remove them instead.</p>
<p>It is possible to reduce the number of entries returned by
<a href="qdir.html#entryList">entryList</a>() and <a href="qdir.html#entryInfoList">entryInfoList</a>() by applying filters
to a QDir object. You can apply a name filter to specify a pattern
with wildcards that file names need to match, an attribute filter
that selects properties of entries and can distinguish between
files and directories, and a sort order.</p>
<p>Name filters are lists of strings that are passed to <a href="qdir.html#setNameFilters">setNameFilters</a>(). Attribute filters
consist of a bitwise OR combination of Filters, and these are
specified when calling <a href="qdir.html#setFilter">setFilter</a>(). The sort order is specified
using <a href="qdir.html#setSorting">setSorting</a>() with a
bitwise OR combination of <a href="qdir.html#SortFlag-enum">SortFlags</a>.</p>
<p>You can test to see if a filename matches a filter using the
<a href="qdir.html#match">match</a>() function.</p>
<p>Filter and sort order flags may also be specified when calling
<a href="qdir.html#entryList">entryList</a>() and <a href="qdir.html#entryInfoList">entryInfoList</a>() in order to override
previously defined behavior.</p>
<a id="the-current-directory-and-other-special-paths" name="the-current-directory-and-other-special-paths" />
<h3>The Current Directory and Other Special Paths</h3>
<p>Access to some common directories is provided with a number of
static functions that return QDir objects. There are also
corresponding functions for these that return strings:</p>
<table class="generic">
<thead>
<tr class="qt-style">
<th>QDir</th>
<th><a href="qstring.html">QString</a></th>
<th>Return Value</th>
</tr>
</thead>
<tr class="odd" valign="top">
<td><a href="qdir.html#current">current</a>()</td>
<td><a href="qdir.html#currentPath">currentPath</a>()</td>
<td>The application's working directory</td>
</tr>
<tr class="even" valign="top">
<td><a href="qdir.html#home">home</a>()</td>
<td><a href="qdir.html#homePath">homePath</a>()</td>
<td>The user's home directory</td>
</tr>
<tr class="odd" valign="top">
<td><a href="qdir.html#root">root</a>()</td>
<td><a href="qdir.html#rootPath">rootPath</a>()</td>
<td>The root directory</td>
</tr>
<tr class="even" valign="top">
<td><a href="qdir.html#temp">temp</a>()</td>
<td><a href="qdir.html#tempPath">tempPath</a>()</td>
<td>The system's temporary directory</td>
</tr>
</table>
<p>The <a href="qdir.html#setCurrent">setCurrent</a>() static
function can also be used to set the application's working
directory.</p>
<p>If you want to find the directory containing the application's
executable, see <a href="qcoreapplication.html#applicationDirPath">QCoreApplication.applicationDirPath</a>().</p>
<p>The <a href="qdir.html#drives">drives</a>() static function
provides a list of root directories for each device that contains a
filing system. On Unix systems this returns a list containing a
single root directory "/"; on Windows the list will usually contain
<tt>C:/</tt>, and possibly other drive letters such as
<tt>D:/</tt>, depending on the configuration of the user's
system.</p>
<a id="path-manipulation-and-strings" name="path-manipulation-and-strings" />
<h3>Path Manipulation and Strings</h3>
<p>Paths containing "." elements that reference the current
directory at that point in the path, ".." elements that reference
the parent directory, and symbolic links can be reduced to a
canonical form using the <a href="qdir.html#canonicalPath">canonicalPath</a>() function.</p>
<p>Paths can also be simplified by using <a href="qdir.html#cleanPath">cleanPath</a>() to remove redundant "/" and
".." elements.</p>
<p>It is sometimes necessary to be able to show a path in the
native representation for the user's platform. The static <a href="qdir.html#toNativeSeparators">toNativeSeparators</a>() function
returns a copy of the specified path in which each directory
separator is replaced by the appropriate separator for the
underlying operating system.</p>
<a id="examples" name="examples" />
<h3>Examples</h3>
<p>Check if a directory exists:</p>
<pre class="cpp">
<span class="type">QDir</span> dir(<span class="string">"example"</span>);
<span class="keyword">if</span> (<span class="operator">!</span>dir<span class="operator">.</span>exists())
<a href="qtcore.html#qWarning">qWarning</a>(<span class="string">"Cannot find the example directory"</span>);

<p>(We could also use the static convenience function <a href="qfile.html#exists">QFile.exists</a>().)</p>

<p>Functions that use Filter enum values to filter lists of files
and directories will include symbolic links to files and
directories unless you set the NoSymLinks value.</p>
<p>A default constructed <a href="qdir.html">QDir</a> will not
filter out files based on their permissions, so <a href="qdir.html#entryList">entryList</a>() and <a href="qdir.html#entryInfoList">entryInfoList</a>() will return all files
that are readable, writable, executable, or any combination of the
three. This makes the default easy to write, and at the same time
useful.</p>
<p>For example, setting the <tt>Readable</tt>, <tt>Writable</tt>,
and <tt>Files</tt> flags allows all files to be listed for which
the application has read access, write access or both. If the
<tt>Dirs</tt> and <tt>Drives</tt> flags are also included in this
combination then all drives, directories, all files that the
application can read, write, or execute, and symlinks to such
files/directories can be listed.</p>
<p>To retrieve the permissons for a directory, use the <a href="qdir.html#entryInfoList">entryInfoList</a>() function to get the
associated <a href="qfileinfo.html">QFileInfo</a> objects and then
use the QFileInfo.permissons() to obtain the permissions and
ownership for each file.</p>

of the <a href="qdir.html">QDir</a> object for directory
<i>dir</i>.</p>
<p><b>See also</b> <a href="qdir.html#operator-eq">operator=</a>().</p>
<h3 class="fn"><a name="QDir-2" />QDir.__init__ (<i>self</i>, QString <i>path</i> = '')</h3><p>Constructs a <a href="qdir.html">QDir</a> pointing to the given
directory <i>path</i>. If path is empty the program's working
directory, ("."), is used.</p>
<p><b>See also</b> <a href="qdir.html#currentPath">currentPath</a>().</p>
<h3 class="fn"><a name="QDir-3" />QDir.__init__ (<i>self</i>, QString <i>path</i>, QString <i>nameFilter</i>, <a href="qdir-sortflags.html">SortFlags</a> <i>sort</i> = QDir.Name|QDir.IgnoreCase, <a href="qdir-filters.html">Filters</a> <i>filters</i> = QDir.AllEntries)</h3><p>Constructs a <a href="qdir.html">QDir</a> with path <i>path</i>,
that filters its entries by name using <i>nameFilter</i> and by
attributes using <i>filters</i>. It also sorts the names using
<i>sort</i>.</p>
<p>The default <i>nameFilter</i> is an empty string, which excludes
nothing; the default <i>filters</i> is <a href="qdir.html#Filter-enum">AllEntries</a>, which also means exclude
nothing. The default <i>sort</i> is <a href="qdir.html#SortFlag-enum">Name</a> | <a href="qdir.html#SortFlag-enum">IgnoreCase</a>, i.e. sort by name
case-insensitively.</p>
<p>If <i>path</i> is an empty string, <a href="qdir.html">QDir</a>
uses "." (the current directory). If <i>nameFilter</i> is an empty
string, <a href="qdir.html">QDir</a> uses the name filter "*" (all
files).</p>
<p>Note that <i>path</i> need not exist.</p>

<h3 class="fn"><a name="absoluteFilePath" />QString QDir.absoluteFilePath (<i>self</i>, QString <i>fileName</i>)</h3><p>Returns the absolute path name of a file in the directory. Does
<i>not</i> check if the file actually exists in the directory; but
see <a href="qdir.html#exists">exists</a>(). Redundant multiple
separators or "." and ".." directories in <i>fileName</i> are not
removed (see <a href="qdir.html#cleanPath">cleanPath</a>()).</p>

<h3 class="fn"><a name="absolutePath" />QString QDir.absolutePath (<i>self</i>)</h3><p>Returns the absolute path (a path that starts with "/" or with a
drive specification), which may contain symbolic links, but never
contains redundant ".", ".." or multiple separators.</p>

<p>This function was introduced in Qt 4.3.</p>
<p><b>See also</b> <a href="qdir.html#setSearchPaths">setSearchPaths</a>().</p>
<h3 class="fn"><a name="canonicalPath" />QString QDir.canonicalPath (<i>self</i>)</h3><p>Returns the canonical path, i.e. a path without symbolic links
or redundant "." or ".." elements.</p>
<p>On systems that do not have symbolic links this function will
always return the same string that <a href="qdir.html#absolutePath">absolutePath</a>() returns. If the
canonical path does not exist (normally due to dangling symbolic
links) canonicalPath() returns an empty string.</p>
<p>Example:</p>

<h3 class="fn"><a name="cd" />bool QDir.cd (<i>self</i>, QString <i>dirName</i>)</h3><p>Changes the <a href="qdir.html">QDir</a>'s directory to
<i>dirName</i>.</p>
<p>Returns true if the new directory exists and is readable;
otherwise returns false. Note that the logical cd() operation is
not performed if the new directory does not exist.</p>

<h3 class="fn"><a name="cleanPath" />QString QDir.cleanPath (QString <i>path</i>)</h3><p>Removes all multiple directory separators "/" and resolves any
"."s or ".."s found in the path, <i>path</i>.</p>
<p>Symbolic links are kept. This function does not return the
canonical path, but rather the simplest version of the input. For
example, "./local" becomes "local", "local/../bin" becomes "bin"
and "/local/usr/../bin" becomes "/local/bin".</p>

<h3 class="fn"><a name="homePath" />QString QDir.homePath ()</h3><p>Returns the absolute path of the user's home directory.</p>
<p>Under Windows this function will return the directory of the
current user's profile. Typically, this is:</p>
<pre class="cpp">
C:<span class="operator">/</span>Documents <span class="keyword">and</span> Settings<span class="operator">/</span>Username
</pre>
<p>Use the <a href="qdir.html#toNativeSeparators">toNativeSeparators</a>() function to
convert the separators to the ones that are appropriate for the
underlying operating system.</p>
<p>If the directory of the current user's profile does not exist or

the given order) until an existing and available path is found:</p>
<ol class="1">
<li>The path specified by the <tt>USERPROFILE</tt> environment
variable.</li>
<li>The path formed by concatenating the <tt>HOMEDRIVE</tt> and
<tt>HOMEPATH</tt> environment variables.</li>
<li>The path specified by the <tt>HOME</tt> environment
variable.</li>
<li>The path returned by the <a href="qdir.html#rootPath">rootPath</a>() function (which uses the
<tt>SystemDrive</tt> environment variable)</li>
<li>The <tt>C:/</tt> directory.</li>
</ol>
<p>Under non-Windows operating systems the <tt>HOME</tt>
environment variable is used if it exists, otherwise the path
returned by the <a href="qdir.html#rootPath">rootPath</a>().</p>
<p>On Symbian this typically returns "c:/data", i.e. the same as

<h3 class="fn"><a name="remove" />bool QDir.remove (<i>self</i>, QString <i>fileName</i>)</h3><p>Removes the file, <i>fileName</i>.</p>
<p>Returns true if the file is removed successfully; otherwise
returns false.</p>
<h3 class="fn"><a name="rename" />bool QDir.rename (<i>self</i>, QString <i>oldName</i>, QString <i>newName</i>)</h3><p>Renames a file or directory from <i>oldName</i> to
<i>newName</i>, and returns true if successful; otherwise returns
false.</p>
<p>On most file systems, rename() fails only if <i>oldName</i> does
not exist, if <i>newName</i> and <i>oldName</i> are not on the same
partition or if a file with the new name already exists. However,
there are also other reasons why rename() can fail. For example, on
at least one file system rename() fails if <i>newName</i> points to
an open file.</p>
<h3 class="fn"><a name="rmdir" />bool QDir.rmdir (<i>self</i>, QString <i>dirName</i>)</h3><p>Removes the directory specified by <i>dirName</i>.</p>

<h3 class="fn"><a name="rmpath" />bool QDir.rmpath (<i>self</i>, QString <i>dirPath</i>)</h3><p>Removes the directory path <i>dirPath</i>.</p>
<p>The function will remove all parent directories in
<i>dirPath</i>, provided that they are empty. This is the opposite
of mkpath(dirPath).</p>
<p>Returns true if successful; otherwise returns false.</p>

<h3 class="fn"><a name="separator" />QChar QDir.separator ()</h3><p>Returns the native directory separator: "/" under Unix
(including Mac OS X) and "\" under Windows.</p>
<p>You do not need to use this function to build file paths. If you
always use "/", Qt will translate your paths to conform to the
underlying operating system. If you want to display paths to the
user using their operating system's separator use <a href="qdir.html#toNativeSeparators">toNativeSeparators</a>().</p>
<h3 class="fn"><a name="setCurrent" />bool QDir.setCurrent (QString <i>path</i>)</h3><p>Sets the application's current working directory to <i>path</i>.

<h3 class="fn"><a name="setFilter" />QDir.setFilter (<i>self</i>, <a href="qdir-filters.html">Filters</a> <i>filter</i>)</h3><p>Sets the filter used by <a href="qdir.html#entryList">entryList</a>() and <a href="qdir.html#entryInfoList">entryInfoList</a>() to <i>filters</i>.
The filter is used to specify the kind of files that should be
returned by <a href="qdir.html#entryList">entryList</a>() and
<a href="qdir.html#entryInfoList">entryInfoList</a>(). See <a href="qdir.html#Filter-enum">QDir.Filter</a>.</p>

<h3 class="fn"><a name="setNameFilters" />QDir.setNameFilters (<i>self</i>, QStringList <i>nameFilters</i>)</h3><p>Sets the name filters used by <a href="qdir.html#entryList">entryList</a>() and <a href="qdir.html#entryInfoList">entryInfoList</a>() to the list of
filters specified by <i>nameFilters</i>.</p>
<p>Each name filter is a wildcard (globbing) filter that
understands <tt>*</tt> and <tt>?</tt> wildcards. (See <a href="qregexp.html#qregexp-wildcard-matching">QRegExp wildcard
matching</a>.)</p>
<p>For example, the following code sets three name filters on a
<a href="qdir.html">QDir</a> to ensure that only files with
extensions typically used for C++ source files are listed:</p>
<pre class="cpp">
<span class="type"><a href="qstringlist.html">QStringList</a></span> filters;
filters <span class="operator"><</span><span class="operator"><</span> <span class="string">"*.cpp"</span> <span class="operator"><</span><span class="operator"><</span> <span class="string">"*.cxx"</span> <span class="operator"><</span><span class="operator"><</span> <span class="string">"*.cc"</span>;

<h3 class="fn"><a name="setPath" />QDir.setPath (<i>self</i>, QString <i>path</i>)</h3><p>Sets the path of the directory to <i>path</i>. The path is
cleaned of redundant ".", ".." and of multiple separators. No check
is made to see whether a directory with this path actually exists;
but you can check for yourself using <a href="qdir.html#exists">exists</a>().</p>
<p>The path can be either absolute or relative. Absolute paths
begin with the directory separator "/" (optionally preceded by a
drive specification under Windows). Relative file names begin with
a directory name or a file name and specify a path relative to the
current directory. An example of an absolute path is the string
"/tmp/quartz", a relative path might look like "src/fatlib".</p>

<h3 class="fn"><a name="setSearchPaths" />QDir.setSearchPaths (QString <i>prefix</i>, QStringList <i>searchPaths</i>)</h3><p>Sets or replaces Qt's search paths for file names with the
prefix <i>prefix</i> to <i>searchPaths</i>.</p>
<p>To specify a prefix for a file name, prepend the prefix followed
by a single colon (e.g., "images:undo.png", "xmldocs:books.xml").
<i>prefix</i> can only contain letters or numbers (e.g., it cannot
contain a colon, nor a slash).</p>
<p>Qt uses this search path to locate files with a known prefix.
The search path entries are tested in order, starting with the
first entry.</p>

<span class="type"><a href="qfile.html">QFile</a></span> file(<span class="string">"docs:design.odf"</span>); <span class="comment">// will look in the :/embeddedDocuments resource path</span>
</pre>
<p>File name prefix must be at least 2 characters long to avoid
conflicts with Windows drive letters.</p>
<p>Search paths may contain paths to <a href="resources.html">The
Qt Resource System</a>.</p>

<h3 class="fn"><a name="setSorting" />QDir.setSorting (<i>self</i>, <a href="qdir-sortflags.html">SortFlags</a> <i>sort</i>)</h3><p>Sets the sort order used by <a href="qdir.html#entryList">entryList</a>() and <a href="qdir.html#entryInfoList">entryInfoList</a>().</p>
<p>The <i>sort</i> is specified by OR-ing values from the enum
<a href="qdir.html#SortFlag-enum">QDir.SortFlag</a>.</p>
<p><b>See also</b> <a href="qdir.html#sorting">sorting</a>() and

<h3 class="fn"><a name="temp" /><a href="qdir.html">QDir</a> QDir.temp ()</h3><p>Returns the system's temporary directory.</p>
<p>The directory is constructed using the absolute path of the
temporary directory, ensuring that its <a href="qdir.html#pathx">path</a>() will be the same as its <a href="qdir.html#absolutePath">absolutePath</a>().</p>

<h3 class="fn"><a name="tempPath" />QString QDir.tempPath ()</h3><p>Returns the absolute path of the system's temporary
directory.</p>
<p>On Unix/Linux systems this is the path in the <tt>TMPDIR</tt>
environment variable or <tt>/tmp</tt> if <tt>TMPDIR</tt> is not
defined. On Windows this is usually the path in the <tt>TEMP</tt>
or <tt>TMP</tt> environment variable. Whether a directory separator
is added to the end or not, depends on the operating system.</p>

<h3 class="fn"><a name="toNativeSeparators" />QString QDir.toNativeSeparators (QString <i>pathName</i>)</h3><p>Returns <i>pathName</i> with the '/' separators converted to
separators that are appropriate for the underlying operating
system.</p>
<p>On Windows, toNativeSeparators("c:/winnt/system32") returns
"c:\winnt\system32".</p>
<p>The returned string may be the same as the argument on some
operating systems, for example on Unix.</p>
