Yeah...I've seen them created two or three times over the past several months...and my OneDrive backup complains about them immediately. (Windows Premier)
I don't know what causes them to be created, but usually occur after/during one of my accesses either to Online or Desktop (don't recall which) software. But with accessing TTX software multiple times every day, the 2 or 3 times generated it hasn't been a major problem.
I've deleted them entirely each time, with no noticeable effect on any of my TTX software, or the files I've accessed....so I've just mentally tossed them off as some strange occasional bug. I really haven't forced a scan on the file with my virus software yet (maybe I should if one shows up again).
