While sharing a file/folder with another Dropbox user, will that file/folder appear in the other user's Dropbox and sync automatically to the Dropbox folder on his computer?
If that user has set the shared file/folder to sync to their computer then yes, it will stay updated when their dropbox syncs.
Keep in mind, though, that there are many ways that the file/folder could be out of sync:
- Other person hasn't turned on their computer
- Other person hasn't turned on syncing for that file/folder
- Other person has
Dropboxsetup to not auto-sync
- Other person has that file open and
Dropboxcan't update the file because it's in use.
