libllfat

This is a library for low-level accessing a FAT12/16/32 filesystem. It offers functions for reading and writing the basic elements of such filesystems such as the number of sectors and the successor of a cluster, but also some more complex operations such as looking up a file and defragmenting a filesystem.

MOVED TO GITHUB

See COPYING for licensing information.

Also see DISCLAIMER: this library has not been extensively tested, and some operations may corrupt the filesystem it is operated upon to the point of making recovery virtually impossible. The suggested application area of this library is for filesystem images that can be easily recreated in case of such failures.

Programs:

fatview

show the structure of a filesystem

fattool

various operations on a filesystem, such as reading and writing a cluster or a file, etc.

fatbackup

copy the essential parts of a filesystem

fatshrink
