 With the aid of free Apple II hacking software like Dalton's Disk Disintegrator (DDD), computer users were able to take an un-protected floppy disk, compress it into multiple files, then transmit those files to another user.This was actually one of several origins of what is known today as peer-to-peer file transfers.While other Apple II-based telecomm programs, such as DiskFur and CatFur, allowed for complete disk and file transfers, there was a need for a portal concept - one that is hosted using a BBS as its entry point.
