Regex for extracting filename from path

Question

I need to extract just the filename (no file extension) from the following path....

\\my-local-server\path\to\this_file may_contain-any&character.pdf

I've tried several things, most based off of something like http://regexr.com?302m5 but can't quite get there

Answer 1

^\\(.+\\)*(.+)\.(.+)$

This regex has been tested on these two examples:

\var\www\www.example.com\index.php
\index.php

First block "(.+\)*" matches directory path.
Second block "(.+)" matches file name without extension.
Third block "(.+)$" matches extension.

Answer 2

This will get the filename but will also get the dot. You might want to truncate the last digit from it in your code.

[\w-]+\.

Update

@Geoman if you have spaces in file name then use the modified pattern below

[ \w-]+\.      (space added in brackets)

Answer 3

This is just a slight variation on @hmd's so you don't have to truncate the .

[ \w-]+?(?=\.)

Demo

Really, thanks goes to @hmd. I've only slightly improved on it.
