fatshrink − reduce the size of a FAT12/16/32 filesystem
fatskrink ([-m] [-t])|[-f] device [sectors]
Reduce the size of a FAT12/16/32 volume by removing the final part of it. Depending on the options, clusters may be moved or files and directories cut to make the filesystem fit the required size.
|
-m |
move the clusters used to store data as the beginning of the volume, to free the space at the end; this may allow shrinking filesystems while preserving their content | ||
|
-t |
truncate the filesystem: if some clusters are in the area that is being cut out (after moving them if -m was also specified), the files and directory using them are truncated | ||
|
-f |
force: reduce the number of sectors without checking the current usage of clusters; this leaves an incorrect filesystem if some clusters that are cut out were in usage | ||
|
device |
the device or image to operate upon |
sectors
the target number of sectors; if the operation is successful (it always is if either -t or -f is given), the resulting filesystem has this number of sectors; if omitted, the program prints the current number of sectors
