I saved an excel file to a floppy that appears to be on the disk but cannot
be retrieved. It may have been read only protected in its original location
but does not appear to be read only now on the floppy. The error message
indicates that it may be read only though. Help.

Those 5 1/4" floppies can be tricky.

Kidding, of course. Can you copy the file to your hard drive? It will
be easier to work from the hard drive if you have to repair the file,
for instance.
