Excel changeing name and type

[terje]

When I open an excel file I some times get's the "unable to read file"
message, what than happends is that excel changes may filename from
filname.xls to something like FB4ED000(I can right click and open this
file in excel an all its fine) What can be doing this and how can I
avoid this from happening so often.

I also have trouble with that I get "unable to read file" when I try to
save a workbook, if I remove the sharing I can save it without this
error, and I can enable the sharing afterwords and still save the
workbook fine. Anyone that have experienced this odd problem before?

Or,
try a harddrive check
from explorer
disk c:\ (or d:\ or whatever)
properties
tools
verify or check for errors or whatever it's called in English.

I don't think the "unable to read file" warning is associated with the funny
named file.

When excel saves the file, it saves it as a temporary file with a funny name (8
characters--no extension).

If the save is successful, xl will delete the original (or rename it to its
backup name (like "backup of book1.xlk)) and if that's successful, xl will
rename the funny named file to the original's name.

Common things that get blamed for interruptions to this process are antivirus
software poking its head in or network errors--either permissions or physical
problems.

And I don't share workbooks, so I don't know if that can cause this kind of
problem--but I don't think anyone has posted messages in the newsgroups
complaining about sharing causing this.

But lots of people have opened an excel file in MSWord and saved (either on
purpose, by mistake or by autosave) that .xls file as an MSWord document (still
with a .xls extension).

This can cause this "unable to read file" error.

If you try opening the file in MSWord and it works, you may be able to save a
little bit of your data--but I would guess you'll have to find a backup.
