I’ve come across this kind of issue in quite a few forms, I wonder if someone can help me understand the logic / algorithm so I know what to expect in the future.
I’ll try do describe the most recent use case in which I encountered this problem.
I’m currently migrating from the unusable Amazon Drive to a seemingly better OneDrive cloud storage. Certain files are already present in both cloud storages, but not necessarily on each client PC. So on one of them I simply want to copy the actual video files from the Amazon Directory to the OneDrive one manually instead of downloading them by syncing (we’re talking about hundreds of gigabytes here). So I copy the files. And then something very strange happens. Some of them are immediately identified as similar to the cloud copy, the corresponding .cloud file disappears and the one I just copied gets the blue check mark badge. Wonderful, just as expected.
But then with some of the copied files (roughly one third of them) it doesn’t happen. Instead, they get the red “syncing” badge and under the “syncing changes” I start seeing some slow progress, per cent after per cent.
Obviously, there is no apparent reason for transferring any data here, since the local and the cloud copies are exactly the same. But worse still, due to the lack of differentiation between download and upload icons (see issue Different Icons for Upload and Download in Odrive context menu) I don’t even know what Odrive is doing: uploading the newly copied files to the cloud or downloading the cloud copies to my local PC.
Any help understanding what and why is happening and how this could be dealt with will be greatly appreciated.
