As you add or remove data from your cloud storage you need to resync the Cloud-synced folder with your cloud storage to keep it up to date.
You cannot change URI after folder creation.
Resyncing data to your Cloud-synced folder scans your bucket for any changes. New files in your cloud storage import to your Cloud-synced folder. Deleted files in your cloud storage are soft deleted in your Cloud-synced folder.
Soft deleted means that the data is not removed physically but is no longer visible to users. Soft deleted data is still available in any Projects where the data resides. Labels can be exported from soft deleted data.
Go to Index > Files > [name of a Cloud-synced folder].
The Cloud-synced folder page appears.
Click Resync.
The resync between the folder and your cloud storage begins.
