I can't figure out why my invert (tilda) syntax isn't working.
Looks like a bug.
I'm not good with wildcards, so I was guessing my syntax was wrong.
I believe the filter should be populating everything except for _2.
try using minus sign instead of tilde.
The behavior looks correct.
You're telling it to show filenames that don't match *_2.
None of the files match *_2, so they're all shown. (Some match *_2.wav and *_2*, but not *_2.)
Galxyhub's suggestion of -_2 will work to exclude files with _2 somewhere in the name, as long as these two options are on:
Yup I forgot about the filename extension, sorry. Putting in .wav fixes it.
