Remove hyphens in filename

I'm wonder if I can use your REGEXP to delete a Hyphen anywhere in the Filename.

Action (quick)
Action type = replace with regex
Field = filename
regexp = "everything you have but replace %TITLE% With %FILENAME%,
replace "
" with"-"
here's my filename example:
katy perry - firework - one - (official - acapella)

The idea is to delete any of these hyphens

THANK YOU

If you want to delete a text constant (and no pattern) use a simple $replace() function or an action of the type simple replace.

If I see your example correctly, you do not only want to replace the hyphen but also the following space character as well.

Sorry, Ohrenkino for not being clear.

This is the filename: Katy - perry - firework - one - (official - acapella)

There are 5 hyphens in the filename. What's the best way to delete one, two, three or all of the hyphens...

Thanks.

Use an action of the type "Replace" for field _FILENAME
Search string: -
Replace string:
(leave empty)

Or use the function Convert>Tag-Tag for _FILENAME
Format string: $replace(%_filename%,- ,)
