How much data can a 700mb CD-rw hold?

A 700 MB CD-RW can hold approximately 700 megabytes of data, which translates to about 80 minutes of audio or around 200-250 standard-quality JPEG images. The actual usable space may vary slightly due to formatting and file system overhead. CD-RWs can be rewritten multiple times, unlike standard CD-Rs, which are write-once.
