This method does not verify that the path or file name exists.
Possible patterns for the string returned by this method are as follows:
- An empty string (path specified a relative path on the current drive or volume).
- "/" (path specified an absolute path on the current drive).
- "X:" (path specified a relative path on a drive, where X represents a drive or volume letter).
- "X:/" (path specified an absolute path on a given drive).
