Split windows path

Question

Can anybody show me how to split windows path on folders, file and drive ? Do I need regex ?

Answer 1

No regex needed use java.io.File part of the standard library.

Especially the getName(), getParent() and getParentFile() methods which will be much simpler.

Answer 2

RegExp? Yes and No - you can use String#split which uses a regular expression even though it often feels like using a normal String:

  String[] parts = "C:\\Program Files\\Application\\config.txt".split("\\\\");

This results in drive (parts[0]), folders (parts[1] and parts[2]) and filename (parts[parts.length-1])

You may have to test if the first segment is a drive name (ends with ":"), the last segment is a file name (file.isDirectory()) and if a segment contains a folder (like no folder in C:\test.txt.
