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

.B \t$ mv FOO Foo
.br
.B \tmv: cannot move \(cqFOO\(cq to a subdirectory of itself, \(cqFoo/FOO\(cq

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