It truncates the file or directory name to the maximum permitted length.

No, it won't find it because it won't be there. In fact this is the simplest
way to find out if a disc is formatted in old or RO4 format.

The logic of this is that, even under RO 3.x, some filing systems could have
long file/directory names, eg. x-files, so the OS commands can cope, it's
the underlying filing systems that can't.
