## Problems and Limitations

### Data Recovery

- DOS, Win9x/ME: unicode symbols in file names outside the selected code page are replaced with "_" or transliterated according to the loaded translit tables
- DOS, Win9x/ME or FAT: unable to recover file greater then 4 GB as a single file due to a FAT limitation
- NTFS alternate streams can be recovered to NTFS volumes only
- One file hard link per NTFS directory is recoverable
- One alt. stream hard link per NTFS file is recoverable
- NTFS symbolic links are not supported
- NTFS encrypted files are not supported
- Win9x/ME: drives greater then 128 GB are not handled correctly without special patches applied to Windows drivers
- Maximum path length supported: 259 characters for DOS, 1024 for Windows, Linux
- Maximum path length supported by DOS: 79 or 127 characters (for DOS-names) depending on DOS version.
- Subdirectory depth is up to 1024 (can be increased using `maxrecoverdepth=` parameter)
- If name substitution is used under DOS then name handling (such as auto renaming) is not supported

### NTFS write support

- Journal is not supported
