I loaded the free version of TonFotos to test it out and have ended up with a massive issue. All my photos are on an 8TB external drive, in a very structured format. The drive, and all the photos, are part of my OneDrive repository. This is on a Windows 11 machine. So C: is my HDD and D: is my 8TB external drive.

I started TonFotos and asked it to index D:\OneDrive\Tera\Pictures and it started with a sub-directory D:\OneDrive\Tera\Pictures\Sport. What I observe is that each file gets duplicated, the new file (based on file date/time) keeps the original name and the old file gets renamed filename-machinename (see below).

If I delete all the -ASUS-ROG. files, I’ll be left with files which do not have the original file date/time stamp.
Is this a OneDrive issue, a TonFotos issue, or a compatibility between the two?

Please help!
Thanks
