Regex remove last folder from path

Question

Using Regex I need to remove the last folder from a path:

Example : C:\Temp\Dir1\

Output : C:\Temp\

Please don't suggest that I can do this with c# or other programming language. I really do need the regex for this.

Thanks in advance for the help.

Answer 1

Replace

[^\\]+\\?$

by nothing. This works for paths like C:\Temp\Dir1 (no trailing backslash) as well. It fails for the root directory of a drive.
