The sync client can run in batches and show that everything has been synced and then start again, and again, and again. It could also be related to not having synced everything 'down' yet. If you don't have another account log in with yours, but keep everything online only.

To test this you can use another computer (that is not currently using the Drive sync client) and log in to another account with access to the same shared drives and keep everything online only and then right-click and check the details. The 'old'? The 'new'? Or another one?Īnd about having more data online than you have locally (now I'm addressing the screenshot from your follow-up) this can also be due to several reasons, but if I had to guess I'd say that you probably have one or more hidden shared drives, or that the file explorer is getting the information about the size from the local cache instead of directly from the cloud. But I'm curious to know which cache folder location is being shown in the Drive sync client settings. For instance, you could have more than one folder with local cache inside the folder in the screenshot (due to previous unnoticed issues, especially related to updates of the sync client). Regarding the difference in sizes (I'm addressing the first screenshots) this could be due to a number of reason.

Your screenshots show custom locations for the cache, which I never recommend, so this could also be related to an issue with the Drive sync client, but it's hard to know without in-depth troubleshooting. Did you delete or made any changes to the local Windows user? Or did you change settings on Windows for the default location of AppData?
