I regularly save documents from Word 2003 onto Zip Disks but just today I got
a message saying that a file from my disk couldn't be opened because of an
I/O error. What is that and what can I do about it?
In general, it's a really bad idea to open Word documents directly on any kind
of removable media because of the way Word uses temporary files in the same
folder as the document.
Can you copy the document from the Zip disk to the hard drive and try to open it
from there?
If it still gives an error, try clicking the down arrow on the Open button in
the File > Open dialog and choosing "Open and Repair".
Another avenue is to try opening the document with WordPad. If it opens, save it
and then try it in Word again. You might lose some formatting.
