EXFAT-FUSE(8) System Manager's Manual EXFAT-FUSE(8)

mount.exfat-fuse - mount an exFAT file system

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

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 available:

Enable debug logging and do not detach from shell.
Ignored.
File system specific options. For more details see FILE SYSTEM OPTIONS section below.
Print version and copyright.
Ignored.

Set the umask (the bitmask of the permissions that are not present, in octal). The default is 0.
Set the umask for directories only.
Set the umask for files only.
Set the owner for all files and directories. The default is the owner of the current process.
Set the group for all files and directories. The default is the group of the current process.
Mount the file system in read only mode.
Do not update access time when file is read.

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

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.
