I wouldn't worry too much about this; after all, we are trying to 
replace a primitive system with a more advanced, user-friendly one.

FWIW, my own implementation uses the names

.path  -> c:\foo\bar  or  \\computer_name\share\dir1\dir2
.vol   -> c:              \\computer_name\share
.dirs  ->   \foo\bar                           \dir1\dir2

.filename ->  some_file.txt  or  archive.tar.gz
.basename ->  some_file          archive
.ext      ->           .txt             .tar.gz
