Why is Excel 2013 getting the 'sorry we couldn't find the FILE NAME.... Is it possible its moved, deleted, renamed'

I've been having this problem for sometime and cannot fix.  It is very intermittent. I have a few networked excel file and on 3-4 computers i can access and open just fine. On couple others i get the error message.  All systems are Windows 7 with office 2013 with full updates.
It is not file length.  I can stick an even longer filename there and it opens fine.
Its not a permission issue because i logged in as same name on each computer and i have max rights.
Its not a profile issue because on the computer where i get the error i get it no matter who i am logged in as.
If i take the file and simply change a letter in the filename, then it opens with no problem. If this was one or 2 files that would be a solution.
I've done uninstalls and re-installs of office and tried comparing all security settings in Excel with the good and the bad and the ones that don't work and do work look identical.

Any thoughts???

Try this...

In windows click Organize in the menu bar, then Layout, then make sure 'Details Pane' is unticked - and also Preview

I've seen this lock the files before and excel/word/etc isn't able to access the file.

Hi gbohrman,

For some reason, that I don't understand, some PC's will not accept "the other slash" in some cases.
So if you try to open the file with  "drive\mypath\myExcel.xlsx", try  "drive/mypath/myExcel.xlsx"

I had the same problem with 2 identical installed PC's reason is unknown
