len(xx) will give you the length of the character variable, in bytes.

Won't you run into the problem that a single file is bigger than a complete floppy disk? Most compression programs have the option of splitting files among more than one floppy disk. Perhaps you should consider this too - for files that are too big for a single floppy, and for more efficient use of available space, in general.
