I have a user I help support who has many .tmp files being created by Excel. I deleted all the .tmp files and turned off the option to save the file every 10 minutes thinking that was causing this problem but they are still being created. I searched this forum and other problems revolving around temp files seemed to stem from addins or code, of which there are none. The only article I could find on the Microsoft knowledge base pertained to Word's creation of temporary files. Does anyone here have any other thoughts on why Excel would create temp files that continue to multiply and are not deleted once Excel is closed.
