The forensic/files directory

The directory forensic/files exists as a sub-directory to the file system root.

The directory is hidden by default. It will appear once forensic mode has been started and processing is completed.

The directory contains a best-effort reconstructed file system reconstructed from potentially recoverable file objects in the kernel. The file objects are retrieved from the kernel pool and process handles.

The file files.txt contains a complete record of the recovered files and their path. It's also possible to view the recovered files by clicking around in the sub-folders. Please note that the reconstruction is a best-effort reconstruction and may contain errors as well as missing files and folders.

Also see the NTFS MFT file recovery module - which may recover small files not visible in this module.

Files in the forensic/files directory and its sub-directories are read-only.

Example

The example shows browsing of the recovered file system, as well as listings of the files in the file files.txt.

For Developers

The forensic/files sub-directory is implemented as a built-in native C-code plugin. The plugin source is located in the file modules/m_fc_file.c in the vmm project.
