FileMapper: Draw pictures of the physical layout of a file system. This tool can walk every file, directory, metadata object, and symbolic link in a file system, record the physical locations of everything it finds, and draw a picture of where everything is located. The analyzer tool can use the FIEMAP or FIBMAP ioctls on a mounted file system to walk the directory tree looking for the data block mappings of files and directories. There is a separate tool that can examine an unmounted ext[234] image; it will find symbolic links and metadata as well. All results are recorded in a sqlite database. Once the filesystem state has been snapshotted in the database, a CLI and a GUI tool can be used to display pictures of where data blocks ended up on the underlying disk. The GUI tool shows the file system tree, a display of the contents of the physical extents on the underlying disk similar to the one in MSDEFRAG, and a list of extents. Selecting a file or a range of physical blocks shows all extents associated with the selection, although more specific queries against the extent table can also be made. DOWNLOADING Clone the git repository at: https://github.com/djwong/filemapper (Sorry, no tarballs or releases yet.) BUILDING Ensure that you have the development files for sqlite3, Qt4, python3, pyqt4, and e2fslibs installed on your system. Then run `make' to build e2mapper. Everything else is written in Python. RUNNING First, index a directory (/home) and store the database (/tmp/some.db): # ./filemapper.py -r /home /tmp/some.db Then fire up the GUI: $ ./filemapper.py -g /tmp/some.db Alternately, examine a raw ext4 image: # ./e2mapper /tmp/some.db /dev/sda1 Examine files in the CLI: $ ./filemapper.py /tmp/some.db >> help LICENSE GPL v2. https://www.gnu.org/licenses/gpl-2.0.html
