This program is very useful! Definetly recommended!
Found the GUI to be anything but intuitive, and there's some basic renaming functionality lacking like the replacing function to include the option of first match only (so important).
Seems to be great, but Recursive selection doesn't seem to work for folders. My folder replacement list is empty in the bottom when it shouldn't. (Without "Recursive" checked there are many subfolders seen with the same replacement)
