<p>QFileInfo provides information about a file's name and position (path) in the file system, its access rights and whether it is a directory or symbolic link, etc. The file's size and last modified/read times are also available. QFileInfo can also be used to obtain information about a Qt <a href="resources.html#resource-system">resource</a>.</p>
<p>A QFileInfo can point to a file with either a relative or an absolute file path. Absolute file paths begin with the directory separator "/" (or with a drive specification on Windows). Relative file names begin with a directory name or a file name and specify a path relative to the current working directory. An example of an absolute path is the string "/tmp/quartz". A relative path might look like "src/fatlib". You can use the function <a href="qfileinfo.html#isRelative">isRelative</a>() to check whether a QFileInfo is using a relative or an absolute file path. You can call the function <a href="qfileinfo.html#makeAbsolute">makeAbsolute</a>() to convert a relative QFileInfo's path to an absolute path.</p>
<p>The file that the QFileInfo works on is set in the constructor or later with <a href="qfileinfo.html#setFile">setFile</a>(). Use <a href="qfileinfo.html#exists">exists</a>() to see if the file exists and <a href="qfileinfo.html#size">size</a>() to get its size.</p>
<p>To speed up performance, QFileInfo caches information about the file. Because files can be changed by other users or programs, or even by other parts of the same program, there is a function that refreshes the file information: <a href="qfileinfo.html#refresh">refresh</a>(). If you want to switch off a QFileInfo's caching and force it to access the file system every time you request information from it call setCaching(false).</p>
<p>The file's type is obtained with <a href="qfileinfo.html#isFile">isFile</a>(), <a href="qfileinfo.html#isDir">isDir</a>() and <a href="qfileinfo.html#isSymLink">isSymLink</a>(). The <a href="qfileinfo.html#readLink">readLink</a>() function provides the name of the file the symlink points to.</p>
<p>On Unix (including Mac OS X), the symlink has the same <a href="qfileinfo.html#size">size</a>() has the file it points to, because Unix handles symlinks transparently; similarly, opening a symlink using <a href="qfile.html">QFile</a> effectively opens the link's target. For example:</p>
<pre>
#ifdef Q_OS_UNIX
QFileInfo info1("/home/bob/bin/untabify");
info1.isSymLink(); // returns true
info1.absoluteFilePath(); // returns "/home/bob/bin/untabify"
info1.size(); // returns 56201
info1.readLink(); // returns "/opt/pretty++/bin/untabify"
QFileInfo info2(info1.readLink());
info1.isSymLink(); // returns false
info1.absoluteFilePath(); // returns "/opt/pretty++/bin/untabify"
info1.size(); // returns 56201
#endif
</pre>
<p>On Windows, symlinks (shortcuts) are <tt>.lnk</tt> files. The reported <a href="qfileinfo.html#size">size</a>() is that of the symlink (not the link's target), and opening a symlink using <a href="qfile.html">QFile</a> opens the <tt>.lnk</tt> file. For example:</p>
<pre>
#ifdef Q_OS_WIN
QFileInfo info1("C:\\Documents and Settings\\Bob\\untabify.lnk");
info1.isSymLink(); // returns true
info1.absoluteFilePath(); // returns "C:\\Documents and Settings\\Bob\\untabify.lnk"
info1.size(); // returns 743
info1.readLink(); // returns "C:\\Pretty++\\untabify"
QFileInfo info2(info1.readLink());
info1.isSymLink(); // returns false
info1.absoluteFilePath(); // returns "C:\\Pretty++\\untabify"
info1.size(); // returns 63942
#endif
</pre>
<p>Elements of the file's name can be extracted with <a href="qfileinfo.html#path">path</a>() and <a href="qfileinfo.html#fileName">fileName</a>(). The <a href="qfileinfo.html#fileName">fileName</a>()'s parts can be extracted with <a href="qfileinfo.html#baseName">baseName</a>() and <a href="qfileinfo-qt3.html#extension">extension</a>().</p>
<p>The file's dates are returned by <a href="qfileinfo.html#created">created</a>(), <a href="qfileinfo.html#lastModified">lastModified</a>() and <a href="qfileinfo.html#lastRead">lastRead</a>(). Information about the file's access permissions is obtained with <a href="qfileinfo.html#isReadable">isReadable</a>(), <a href="qfileinfo.html#isWritable">isWritable</a>() and <a href="qfileinfo.html#isExecutable">isExecutable</a>(). The file's ownership is available from <a href="qfileinfo.html#owner">owner</a>(), <a href="qfileinfo.html#ownerId">ownerId</a>(), <a href="qfileinfo.html#group">group</a>() and <a href="qfileinfo.html#groupId">groupId</a>(). You can examine a file's permissions and ownership in a single statement using the <a href="qfileinfo.html#permission">permission</a>() function.</p>

<h3 class="fn"><a name="QFileInfo-3" />QFileInfo.__init__ (<i>self</i>, <a href="qfile.html">QFile</a> <i>file</i>)</h3><p>Constructs a new <a href="qfileinfo.html">QFileInfo</a> that gives information about file <i>file</i>.</p>
<p>If the <i>file</i> has a relative path, the <a href="qfileinfo.html">QFileInfo</a> will also have a relative path.</p>
<p>See also <a href="qfileinfo.html#isRelative">isRelative</a>().</p>
<h3 class="fn"><a name="QFileInfo-4" />QFileInfo.__init__ (<i>self</i>, <a href="qdir.html">QDir</a> <i>dir</i>, <a href="qstring.html">QString</a> <i>file</i>)</h3><p>Constructs a new <a href="qfileinfo.html">QFileInfo</a> that gives information about the given <i>file</i> in the directory <i>dir</i>.</p>
<p>If <i>dir</i> has a relative path, the <a href="qfileinfo.html">QFileInfo</a> will also have a relative path.</p>

<h3 class="fn"><a name="absoluteFilePath" /><a href="qstring.html">QString</a> QFileInfo.absoluteFilePath (<i>self</i>)</h3><p>Returns the absolute path including the file name.</p>
<p>The absolute path name consists of the full path and the file name. On Unix this will always begin with the root, '/', directory. On Windows this will always begin 'D:/' where D is a drive letter, except for network shares that are not mapped to a drive letter, in which case the path will begin '//sharename/'.</p>
<p>This function returns the same as <a href="qfileinfo.html#filePath">filePath</a>(), unless <a href="qfileinfo.html#isRelative">isRelative</a>() is true.</p>
<p>If the <a href="qfileinfo.html">QFileInfo</a> is empty it returns <a href="qdir.html#currentPath">QDir.currentPath</a>().</p>
<p>This function can be time consuming under Unix (in the order of milliseconds).</p>
<p>See also <a href="qfileinfo.html#isRelative">isRelative</a>() and <a href="qfileinfo.html#filePath">filePath</a>().</p>

<h3 class="fn"><a name="created" /><a href="qdatetime.html">QDateTime</a> QFileInfo.created (<i>self</i>)</h3><p>Returns the date and time when the file was created.</p>
<p>On most Unix systems, this function returns the time of the last status change. A status change occurs when the file is created, but it also occurs whenever the user writes or sets inode information (for example, changing the file permissions).</p>
<p>If neither creation time nor "last status change" time are not available, returns the same as <a href="qfileinfo.html#lastModified">lastModified</a>().</p>

<p>The <i>file</i> can also include an absolute or relative file path. Absolute paths begin with the directory separator (e.g. "/" under Unix) or 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>Example:</p>
<pre>
QString absolute = "/local/bin";
QString relative = "local/bin";
QFileInfo absFile(absolute);
QFileInfo relFile(relative);
QDir.setCurrent(QDir.rootPath());
// absFile and relFile now point to the same file
