How do I rename 96 parts in a file?

I have 96 part files and 12 assembly files on a project. Iwant to rename them all by adding a suffix and saving them to adifferent file, but still keep my original files without changingtheir name. Can Solidworks explorer do this? Is there any way I cando them all at once, or do I have to change them one at a time.---BrianSolidworksGeneral
