Shell operations greyed out :( can I delete Roms from RC?

[petruza.d64]

Hi, I've loaded the NES datfile from TOSEC, and set the rom path, evrything's fine, but:
I filter files by "" for example, to tell apart bad dumps (tosec naming convention), can I do anything with the selected roms aside from generating a report?
I mean, I wish to just delete the files. I can imagine the "shell operations > Delete files" would do that, but no matter what, it's always greyed out.
Am I doing something wrong?

Thanks!!

Yes, you're doing something wrong.
In order to remove or fix some files, you need to select some files.

Expand your roms path, select a file and the tools will be available.
