ClearMAME is used to manage a collection of files. Some examples are:
MAME ROM collection
MAME Sample collection
RAINE ROM collection

To use ClearMAME, you need either the Dat file for the collection, or the program (needs to provide either a -listXML or -listinfo output) to provide the information on the collection.

Suggest that you read thru the ClearMAME Help for further information.
