Bulk Rename Utility

I am trying to correct a backup that has stuck the date and time on the end of almost every single file.
I am trying to remove (date UTC) from the end of file names. I can do this by going into each folder individually but sometimes there are folders within folders within folders.
Any quicker way to do this?

Inside of the Filters(12) to put a checkmark in "Subfolders".

Do i have to configure further if there are folders within the subfolders?

This depends on what means configure?? A checkmark in 'Subfolders' will present all sub-folder depths.
To specify a maximum sub-folder depth, you can put a number inside for 'Lvl'.
A checkmark in 'Folders' will present folders, and 'Files' does present files.
