I've been working at this issue for some time now and all the advice I
have tried has failed.

Familiar problem:

I attempt to open a excel file from my A: drive and of course it says,
"The file may be read-only, or you may be trying to access a read-only
location."

The other files, non-excel, on the disk open just fine.

So I checked the file properties and the  "read-only" box is unchecked.
I messed around with this for 30 minutes and nothing changed. Rebooted
several times. Cleaned win temp and anything to do with excel.

I was told to copy and paste the file onto my destop through Win
Explorer. No change.

Tried renaming it. No change.

I attempted to open the file on my friend's computer and same issue.

Any advice? The file is on a 3 1/2 floppy.
