NAME
       defrag.exfat - Defragment or assess fragmentation on an exFAT
       filesystem


SYNOPSIS
       defrag.exfat [-f | -a] device

       defrag.exfat -h | --help

       defrag.exfat -v | --version


DESCRIPTION
       defrag.exfat is a utility to defragment files on an exFAT-formatted
       device or assess its current fragmentation status.

       Defragmentation reorganizes scattered file clusters into contiguous
       blocks, which may improve I/O performance -- especially on mechanical
       storage devices.

       By default, when no option is specified, the tool will prompt the user
       with a warning recommending to run fsck.exfat first to ensure
       filesystem consistency.

       This safety prompt can be bypassed using the -f option.

       The -a option enables assessment mode, which analyzes fragmentation
       without modifying the filesystem.

       The target device must be unmounted before running this command.


OPTIONS
       -f, --force
              Perform defragmentation without prompting the fsck warning. Use
              with caution.

       -a, --assessment
              Assess the fragmentation status of the exFAT volume without
              making any changes.

       -v, --version
              Display version information and exit.

       -h, --help
              Show usage information and exit.


EXAMPLES
       Defragment an unmounted exFAT device (with safety warning):
       $ defrag.exfat /dev/sda1


       Defragment without prompting (force mode):
       $ defrag.exfat -f /dev/sda1


       Assess fragmentation status (read-only):
       $ defrag.exfat -a /dev/sda1


       Show version:
       $ defrag.exfat -v


       Show help:
       $ defrag.exfat -h


NOTES
       It is strongly recommended to run fsck.exfat on the device before
       defragmenting to ensure filesystem integrity.

       Always backup critical data before defragmenting.
