Which platforms support viewer info?

Note: If someone is viewing your file using macOS 10.14 (Mojave) they may need to enable additional settings first.
How did someone get access to a file?
Shared folder members who Can edit the folder can invite people to the folder. Click Share on a file to see what permissions (Can edit or Can view) someone has.
If you’re the owner of a shared folder, you can restrict who can invite people to the folder.
If you see a Guest on your file, that guest accessed the file through a shared link. A Guest may be someone who can access a file, but is viewing a shared link when they’re not signed in.
Why don’t I see a person I gave access to?
If more than four people viewed a file, you see an icon with a number on it on the preview of the file on dropbox.com. This icon shows how many people viewed the file. Click this icon to see everyone who accessed to the file.
If you don’t see the person you’re looking for, they might not have viewed the file yet, or viewed the file when they weren’t signed in. If they’re not signed in, they’re shown as a Guest when they view the file.
Viewer info settings
If viewer info is disabled for a shared folder, viewer info is also disabled on all content in that folder. If viewer info is disabled for a shared folder, only the owner can enable viewer info on individual files in that shared folder.
If viewer info is enabled for a shared folder, the owner or an editor can disable viewer info for specific files in that folder. Members who Can edit the folder can disable viewer info for files in a shared folder.
When you move a file into a shared folder, the file adopts the same viewer info setting as the shared folder. If you move a file into a shared folder you don’t own, the owner may have different settings for viewer info.
Note: If you changed the viewer info setting on your file before moving it into another folder, it usually keeps the setting you chose.
