## Now open and read the file specified
## Step 1: get an IMG_INFO object (url can be any URL that AFF4 can
## handle)
img = pytsk3.Img_Info(url)
## Step 2: Open the filesystem
fs = pytsk3.FS_Info(img)
## Step 3: Open the file using the inode
f = fs.open_meta(inode = inode)
## Step 4: List all blocks allocated by this file. Note that in some
## filesystems each file has several attributes and each can allocates
## multiple blocks. So we really need to iterate over all attributes
## of each file:
for attr in f:
print "Attribute %s, type %s, id %s" % (attr.info.name,
attr.info.type,
attr.info.id)
for run in attr:
print " Blocks %s to %s (%s blocks)" % (run.addr, run.addr + run.len, run.len)
