What's wrong with unk extension?
Posted on 2001-09-06
Hi, my customer send a mail and attached an Excel file to 3 person(A,B and C).However, only C received it without any problem. The *.xls file can be opened and displays content.
A and B both received the same mail but the file-icon was replaced to "att-1.unk".Since the View and Launch do not work, they detach it to disk, and then rename to att-1.xls to force Excel to open. But they see garbage displayed inside Excel.
What's the problem here?
Any solution for that?
