Bulk Rename Utility

I'm blind and these fields are a bit tricky to work with but so far it's been ok, Although some of the menu items aren't actually labeled so if you could label them that would be amazing!

Anyway, I've renamed files but now I need to remove a space from in front of each file. For example, instead of file 1.mp3 it's showing up as space file 1.mp3

I can't figure out how to do this and would apreciate the help.

I decided to redo the entire thing, i'll redownload the stuff from youtube and go from there.

The easiest way is using Replace(3) with a "Replace" something like... \start\ .
But if wanting to conduct everything with only 1-rename, then its better just using Regex(1).
This because Replace(3) wont conduct both \modifiers\ and | for many-replacements, at the same time.
