SUMMARY On Windows, OneDrive uses placeholder files that are downloaded lazily from the cloud. When you start digiKam it will try to scan all pictures in ~/OneDrive/Pictures, triggering download of all of them. Given that this is a very serious operation and may fail and make computer problematic/unusable if C: drive runs out of space I think digiKam should detect placeholder files and provide suitable warning before proceeding. PS. Other cloud storage clients may do lazy downloads too (e.g. Google Drive FileStream), perhaps even on mac.
You should not have such virtual placeholder folders within the image collection specified in digiKam. I also think that currently we have no way to detect if the folder is a virtual cloud folder via the Qt API. Maik
