Moving folders · Moving folders to a cloud account
Are file dates kept when I move files to a cloud account?
Short answer: It depends on the service. Most keep the modified date, and Google Drive also keeps the created date, but Mac-specific details like Finder tags and permissions generally aren't stored by cloud services. Moves to your fast drive keep them.
It depends on the service, not on Storage Studio. Most cloud services keep a file's modified date; Google Drive also keeps the created date. Finder tags, permissions and other Mac-specific details generally aren't something cloud services store.
Moving into iCloud Drive through its folder on your Mac behaves like a move on your Mac, because macOS handles it.
If those details matter for a folder, move it to your fast drive instead, where they come across. See Does moving keep dates and tags?
