Finder shows you with small icons the status of each Companion file, so you know at a glance what's downloaded, what's in the cloud, and what's syncing.
The statuses
- Cloud: the file is in Basecamp but not on your Mac. It downloads when you open it.
- Downloaded: you have a local copy; it opens instantly and works offline.
- Always downloaded: you pinned it with Always Keep on Device; macOS won't release it.
- Syncing: Companion is uploading or downloading that file right now.
Note: you can add Finder columns (right-click on the column header) to also see the modification and creation date of each file.
