The help file explains that the selection box accepts wildcards and multiple values...separated by spaces! This means it's impossible to pre-select a list of files if they contain spaces and you are trying precisely to narrow down those with and without spaces. The help file doesn't say how to work around spaces in filenames, and the forum search box doesn't accept "select" or "space" because they are too common words

Here is what I am trying to do:
- I have a few thousand mp3 which start by e.g. 00-songname.mp3 or 00 - songname.mp3 or 00- songname.mp3 or 00 -songname.mp3
- I want to remove all the prefixes 00- and "00 - " and "00 -" and "00- " in order to end up with "songname.mp3" only
Removing a few characters in front is easy with BRU (filter #5). Using a selection filter of eg "* - *.mp3" selects (all the files + any file with a dash + any mp3 file)...which is useless for my purpose

The files in left pane are listed in alphabetical order, and I see a small range of "xx-songname" followed by a small range of "xx -songname" and "xx- songname" and finally "xx - songname". It would be easy to select manually if I had a dozen files, but here I have to manually select every single of a few thousand files

There has to be a better way. Thousands thanks to the kind smart guy/gal who can help me!
PS: I think this case should be documented in the help file, as spaces in filenames is a common thing and it's the only exception I can see in the selection filter.
