+.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.
