Any file that does not exceed the capacity of the disk will fit. In fact, software that can span multiple disks can be used to store even larger files but this should not be a problem. You said CD-RW which means it's rewritable. It will require formatting and this will mean some loss in capacity. CD-Rs a dirt cheap and, using "multisession" can be added to until they fill. CD-Rs are an excellent way to backup your other software disks. Put the originals away for safe keeping and use the copies for software installation. This is legal.
What can be stored on CD-RW?
Is it just for music and photos or can you also store word/word processing files? Just bought a laptop for my daughter for college and I want to know what are her storage options. I did get a 256 MB flash drive also.
