well so far I had no issue with SyncBack (Free version on windows 10 64bits) but since the latest upgrade, I ran into one.
Synckback somehow 'refuses' to see that files in source folder exist and insist on copying them onto the destination fodler (an external HDD).
When I click on details, it says 'file doesn't exist in source' (I'm in mirroring mode)
I don't know what's going on, the timestamps are different on both files (creation and modification) but I haven't modified them. Besides how can the software see details of the file and then tell me the source file doesn't exist (be it pictures or sound files)
For info, tried the trial SE Version and ran into the same issue.
It's all confusing for me

All the best,
Phil
