Excel file Keep create .tmp file

Hi,

There are different reasons why Excel creates temporary files when you save a file. Sometimes, this may be caused by a third-party Excel add-in or an Antivirus software conflict. For us to determine what's really causing this issue, try to start your computer in Safe mode.

Safe mode is a diagnostic mode for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. This will help us in identifying whether the issue is due to some third party program conflict.

Once you're on Safe Mode, try to save a file and check if same issue still occurs. If there is no temporary file created, then it means that this is caused by add-ins. First, try to inactivate the Excel add-ins. Follow the steps listed on this support article to inactivate Excel add-ins. Please be reminded that the article applies to Excel 2016, Excel 2013, Excel 2010, and Excel 2007. By the way, which version of Excel do you have?

Feel free to get back to us anytime and update us on how it goes.
