I don't know about you, but I consider that to be a bug.

A workaround might be to use rename() for simple renames and only
resort to NSFileManager for actual move operations... something like
this:

if (rename ([oldName fileSystemRepresentation],
[newName fileSystemRepresentation]) < 0) {
if (errno == EXDEV) {
if (![[NSFileManager defaultManager] movePath:oldName
toPath:newName
handler:nil]) {
/* Failure */
}
else {
/* Failure */
}
}

Kind regards,

Alastair.
