Hi Mike,
Thanks for the response. Unfortunately this is not the problem. It happens
even if I attempt to open a file in the root of C drive as in C:book1.xls.
The whole filepath and name is visible in the error message.
Regards,
Morpheus

One possibility is that the file is nested too deep in the filing system.

There is a limit to the number of characters that can be used for a file
path. For Excel I thing this is about 234; for Windows it is more.

See if the name given in the "cannot open..." message has been truncated.
If so, then shorten the file name, or move it higher up the structure.

I have a strange problem when I try to open an Excel file from My Computer or
Windows Explorer. I get an error message to the effect that "Windows cannot
find the file c:\book1.xls' ,etc. etc. although the file definitey exists.
Not too sure what I've done, but any help fixing this problem would be most
gratefully received.
