## Usage

dumpexfat

    $ ./target/release/dumpexfat

    Usage: ./target/release/dumpexfat [-s] [-u] [-f file] [-V] 

    

    Options:

        -s                  Dump only info from super block. May be useful for

                            heavily corrupted file systems.

        -u                  Dump ranges of used sectors starting from 0 and

                            separated with spaces. May be useful for backup tools.

        -f            Print out a list of fragments that compose the given

                            file. Each fragment is printed on its own line, as the

                            start offset (in bytes) into the file system, and the

                            length (in bytes).

        -V, --version       Print version and copyright.

        -h, --help          Print usage.

exfatattrib

    $ ./target/release/exfatattrib

    Usage: ./target/release/exfatattrib [FLAGS] -d  

    

    Options:

        -d          The path to an unmounted disk partition or disk image

                            file containing an exFAT file system. This option is

                            required.

        -r                  Set read-only flag

        -R                  Clear read-only flag

        -i                  Set hidden flag (mnemonic: invisible)

        -I                  Clear hidden flag

        -s                  Set system flag

        -S                  Clear system flag

        -a                  Set archive flag

        -A                  Clear archive flag

        -V, --version       Print version and copyright.

        -h, --help          Print usage.

    $ ./target/release/exfatfsck

    exfatfsck 1.4.0

    Usage: ./target/release/exfatfsck [-a | -n | -p | -y] [-V] 

    

    Options:

        -a                  Automatically repair the file system. No user

                            intervention required.

        -n                  No-operation mode: non-interactively check for errors,

                            but don't write anything to the file system.

        -p                  Same as -a for compatibility with other *fsck.

        -y                  Same as -a for compatibility with other *fsck.

        -V, --version       Print version and copyright.

        -h, --help          Print usage.

    Options:

        -V, --version       Print version and copyright.

mkexfatfs

    $ ./target/release/mkexfatfs

    mkexfatfs 1.4.0

    Usage: ./target/release/mkexfatfs [-i volume-id] [-n label] [-p partition-first-sector] [-s sectors-per-cluster] [-V] 

    

    Options:

        -i       A 32-bit hexadecimal number. By default a value based

                            on current time is set. It doesn't accept 0x or 0X

                            prefix.

        -n     Volume name (label), up to 15 characters. By default

                            no label is set.

        -p 

                            First sector of the partition starting from the

                            beginning of the whole disk. exFAT super block has a

                            field for this value but in fact it's optional and

                            does not affect anything. Default is 0.

        -s 

                            Number of physical sectors per cluster (cluster is an

                            allocation unit in exFAT). Must be a power of 2, i.e.

                            1, 2, 4, 8, etc. Cluster size can not exceed 32 MB.

                            Default cluster sizes are: 4 KB if volume size is less

                            than 256 MB, 32 KB if volume size is from 256 MB to 32

                            GB, 128 KB if volume size is 32 GB or larger.

        -V, --version       Print version and copyright.

        -h, --help          Print usage.

modexfatfs

    $ ./target/release/modexfatfs

    modexfatfs 1.4.0

    Usage: ./target/release/modexfatfs [-c "fail"|"ignore"|"unlink"] [-V]   [...]

    

    Options:

        -c, --conflict <"fail"|"ignore"|"unlink">

                            Action to take when a given path already exists within

                            . "fail" fails with EEXIST unless both paths

                            are directory. "ignore" ignores a given path and

                            leaves the existing path as is. "unlink" unlinks the

                            existing path first and then create. Unlink of

                            directory (and its child entries) is unsupported.

                            Defaults to "fail".

        -V, --version       Print version and copyright.
