I have used a thumbdrive for my daily excel sheet working for a several months now.
I normally open a file and work on it during the day and save it spasmodically during the day.
I also move the thumbdrive between computers, copying other files etc.
No problems until a week ago, when I first started noticing "TMP" files being left visible on the thumbdrive subdirectory while I am working with excel.
The visible TMP files seem to be about every half-hour or so - I guess whenever I "saved" the file & left it open to continue working.
As a test, I tried the same thing from a copy of the file on the harddrive of my computer and NO TMP files were visible.
Why only the thumbdrive ?
Why did it start only a week ago when everything was fine for months beforehand ?
How do I fix it so the TMP files are not visible ?
System is :
HP laptop / 16gb
Win 11
Office Home & Student 2019
Many thanks for any answers.
