Subject Re: [io] Filename prefixes
Date Mon, 22 Nov 2004 01:17:40 GMT
Basically it looks like we'll need:

getPrefix()  - C:\
getPath()  - dev\project
getFullPath()  - C:\dev\project
getName()  - file.txt
getExtension()  - txt
(input  C:\dev\project\file.txt)

Normalize/catPath can then use the other methods to stitch together a
result.

Naming:
catPath() should be renamed to concat()
getFullPath()/getPath() - are these logical names?
