Floppy diskettes are more convenient, affordable, and popular than cartridge tapes but not as universal. If you have a PC running a terminal emulator program such as Kermit, Versaterm-Pro, or Telnet, you can use that PC to make or read copies of your files on floppy diskettes. Programs designed for a PC will not generally run under the operating systems present on workstations (or other PCs). The safest approach is to make sure the PC saves the file in ASCII, text, or source form, and transfer these. We discuss this further in Chapter 3, Computer-Computer Interactions.
