Dopus Always shows the status and availability of all OneDrive folders and files as "Sync Pending" while the status and availability in Explorer are shown correctly.
That's in addition to Dopus going postal and seemingly randomly downloading .zip and .exe files on entering a folder that contains any of those, even with a default Dopus config. Windows Explorer doesn't do anything like that.
Troubleshooting steps I've tried:
Reset Folder type format
Complete Uninstall/Reinstall of Dopus 12.12.2 beta and test with default config
Complete Uninstall/Reinstall and revert to Dopus 12.12 and test with default config
OneDrive Uninstall/Reinstall including physically deleting the OneDrive folder on disk
OneDrive Version Is Windows 10 (not Office 365) Build 19.033.0218.0006 (in the current Win 10 build they appear to be identical, downloading it from office.com grabs the same build)
All to no avail, so any help/hints would be immensely appreciated
Coincidentally I saw this for the first time yesterday, while I was debugging a separate OneDrive problem. I actually don't think it's anything the new beta will help with unfortunately. It seems to be a bug in OneDrive itself - sometimes, for some reason, the OneDrive DLL starts returning the wrong status to us for all files.
Obviously Explorer uses a different mechanism to query for file status but unless we can find out what that is there doesn't seem to be anything we can do about this in the short term.
I had it happen twice; the first time it resolved itself after a reboot, the second time I was able to fix it by a complete uninstall of OneDrive (including deleting the folder, as you did, but also deleting the OneDrive data directory in %LocalAppData%).
I followed the instructions here, for what it's worth:
