Memo attached file

Hello,

We attach excel spreadsheets such as vendor price list (not large 75k) to memo's when we try to open some that are located on a shared server (not sage server) they won't open, Sage will kick us back to vendor entry screen.  In the past I was told that if the url is more then 250 characters Sage doesn't like it however, these files are only about 100 characters and less in length..  

To test I used a different file in same shared directory and I was unsuccessful to open I also moved the original file into a folder on the Sage server tried to open in vendor inquiry and maintenance both times Sage kicked me back to entry screen. 

Any ideas??
