When you add files to your favorites, the files are always available to you for offline viewing. You can access these files anytime, anywhere.

If your administrator enabled favorites for you, you can add files to your favorites. You can access these files without internet connectivity.

If your administrator did not enable favorites for you, you cannot add files to your favorites. This scenario is quite possible if your enterprise works with official or confidential files and they do not want its employees to access these files offline.
