Hello everyone I need some help. When I right click on an excel attachment and click save as I always have to type in the extension even though my file extensions are hidden. The save as type: is set to All files. The drop down menu does not have excel. If I open the file and click save as it automatically saves as an excel docment. Please help me correct this. I just formatted my computer and this issue was not present before the cleaning.

Thanks in advance.
