FS_Forensic_Ntfs
The directory forensic/ntfs 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-efford reconstructed file system reconstructed from NTFS MFT entries located in physical memory. If the files are small enough contents may reside within the NTFS MFT and may be recoverable by opening the file.
The file ntfs_files.txt contains a complete record of the recovered NTFS MFT enties 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-efford reconstruction and may contain errors as well as missing files and folders.
Each folder contains a special meta-data folder named _$INFO. The _$INFO folder contains a directory populated with metadata information about the NTFS MFT record. The metadata files are:
| File | Description |
|---|---|
| mftinfo.txt | Information in easy-to-read format about the MFT entry. |
| mftdata.mem | The 1024 byte long MFT record. |
| mftfile.bin | The file representation, if file and data recoverable. |
The file ntfs_files.txt have the following format:
# PHYS_ADDR RECID TIME_CREATE TIME_MODIFY SIZE AVAIL DIR PATH

Files in the forensic/ntfs directory and its sub-directories are read-only.
The example shows browsing of the user desktop folder, as well as listings of the files in the file ntfs_files.txt.
The forensic/ntfs sub-directory is implemented as a built-in native C-code plugin. The plugin source is located in the file modules/m_fc_ntfs.c in the vmm project.
