A portable storage case which can accommodate both compact discs and 3.5 inch floppy diskettes. The portable storage case comprises a plurality of pages, each page having a plurality of storage sections, each storage section accommodating one compact disc or one floppy diskette. Each storage section comprises a plurality of fastening prongs which are arranged in a circular orientation; a compact disc or a floppy diskette may be stored in one of these sections by depressing it into the circular orientation of the fastening prongs. Because the fastening prongs are flexible and yielding, they clamp onto the disc/diskette and hold it firmly in place.
