Can I open the files that are stored in the connected accounts in those accounts directly from Koofr?

You can do that only for the files that are stored in your connected Google Drive account. There are two ways to do this:

  1. If you view a file in the Koofr integrated file viewer, you can open it in Google Drive by clicking the Open in Google Drive button on the upper right side.
  2. If you are viewing your Google Drive files in Koofr, right-click on the wanted file and select Open in Google Drive from the drop-down menu.
