$R0 is now "files"
$R0 is now "files"
 
Push "." instead of "\" to get a file extension or perhaps "/" for URL.
You can also use this function to get the file extension of an entered file path.
In the function replace...
:StrCmp $2 "\" exit
...with
:StrCmp $2 "." exit
 
The file extension (after the ".") will then be popped off the stack.

(I also wrote a similar script, but this one is better)
