I just tested this regex (and compressed all 3 files):[xyz].txt
Make sure the Is regex checkbox is checked.
Use the Test tab to test your regex. It will show the files it will compress.
I also used your expression: x.txt|y.txt|z.txt
and this one works also. It compresses all three files.
Please check the path and use the Test tab to check the files hit by your file filter setings.
