It might possible to do this, but some problems would remain:

• How do we detect whether special handling (splitting) is necessary? That might be very tricky. Adding an option to make it possible for the user to explicitly enable this behavior sound easier.

• If there is no safe way to change to the FTP root directory, then how would we do that? One possible method would be to call CDUP command repeatedly until the directory is unchanged or until it fails, but whether this would be reliable is hard to tell. What if we don't have access rights to one of the intermediate folders?

• What about other methods? If ChangeDirectory automatically simulated '/' on servers using a different delimiter, users would expect that other methods behave the same way. This would add lot of complexity, because we would have to change to the target folder first, then perform the desired action and then change back to the original folder. I'm not sure the effort would really be worth it.

Any comments are appreciated.
