How to Remove Unwanted ROMs in Launchbox MAME Arcade Set

Hi everyone,

I recently imported a complete MAME Arcade set into Launchbox, but due to some filters I applied during the import process, only 3,000 out of the 12,000 games were added to my library. However, all 12,000 games remain in the MAME folder.

My question is: can I export the 3,000 ROMs from Launchbox to a new folder and then delete all the ROMs from the original MAME folder, and finally add the exported 3,000 ROMs back to the MAME folder? Will this work?

I appreciate any help or suggestions. Thank you!

If you have a non-merged romset, then you could potentially use the option under Tools > File Management > Export/Copy ROM Files from Selected Games to New Folder...

If you have either a merged or split set, then there's not a great way to clean up the folder, as each game ROM may have a number of other files as dependencies, and you'll break the games by using that utility.

Thank you for your response.

My MAME Arcade set is actually a merged set. I see what you mean about using the "Export/Copy ROM Files from Selected Games to New Folder" option possibly breaking the games due to dependencies.

In that case, is there any other option to clean up the MAME folder and remove the unwanted ROMs in a merged set? I appreciate any suggestions.
