[cfAPI] File created with Cloud Filter API might be deleted by other cloud provider

Chieh Yu 1

Hi guys, I'm currently developing a product using cloud filter API. Some of our customer report that while they uninstall OneDrive, all the file (placeholder) created by our product will also be deleted.

In the past, we use AckDelete to prevent being deleted by OneDrive by checking whether the program name in the callback is OneDrive or not. But this trick can no longer used due to bug reported in here. Is there any other way to prevent this thing happen?

Another issue is reported by onwCloud in their blog. Some API were changed in 2020H2 and lead to files being deleted. Can cloud filter API developer share some information about what APIs changed? or error code did changed? Then we can fix the issue and prevent our customer's lost.

Thanks.

Hello @Chieh Yu , uninstall OneDrive cause placeholders created by Cloud Filter API be deleted, yes, I can reproduce this issue on Windows 10 20H2 (Build 19042.630). I'll confirm this issue internally.

Looking forward to hearing from you!

This can make sure placeholder files created by Synology Drive, iCloud Drive, or ownCloud client can be safed.
