I'd change "currentDir" with e.g. "currentDirSymbol" or something. 
Otherwise people may actually thing currentDir is pwd. Same about parentDir.

I'm not fond of adding support for extensions. On Unix there's no 
explicit extension. Extension comes from CP/M with 8 characters for name 
and 3 characters for extension, which is now long defunct.

"dirname" will be instantly recognized by any Unix user.
