Looking for a quick way to remove bad roms

[Quest]

Is there a quick way to remove bad roms form the rom folder other than removing them one by one?

Also when you have roms with crc errors can they be repaired or are they useless?

Thank you :)

Use some auditing tools such like RomCenter or ClrMAME which done better job. :)
