SYNOPSIS

mount.exfat-fuse [ -d ] [ -n ] [ -o options ] [ -V ] [ -v ] device dir

DESCRIPTION

mount.exfat-fuse is a free exFAT file system implementation with write support. exFAT is a simple file system created by Microsoft. It is intended to replace FAT32 removing some of its limitations. exFAT is a standard FS for SDXC memory cards.

COMMAND LINE OPTIONS

-d: Enable debug logging and do not detach from shell.
-n: Ignored.
-o options: File system specific options. For more details see FILE SYSTEM OPTIONS section below.
-V: Print version and copyright.
-v: Ignored.

FILE SYSTEM OPTIONS

dmask=value: Set the umask for directories only.
fmask=value: Set the umask for files only.
uid=n: Set the owner for all files and directories. The default is the owner of the current process.
gid=n: Set the group for all files and directories. The default is the group of the current process.
ro: Mount the file system in read only mode.
noatime: Do not update access time when file is read.

EXIT CODES

Zero is returned on successful mount. Any other code means an error.

BUGS

exFAT is a case-insensitive file system. Some things can behave unexpectedly, e.g. directory renaming that changes only case of some characters:

$ mv FOO Foo
mv: cannot move 'FOO' to a subdirectory of itself, 'Foo/FOO'

This happens because mv finds that destination exists (for case-insensitive file systems FOO and Foo are the same thing) and adds source basename to the destination. The file system gets rename("FOO", "Foo/FOO") syscall and returns an error.
