You can use the Control Center app to download large content files that aren't added to Dropbox.
When downloading service files, a connection is made to the read-only Services network storage drive. You can browse this drive by selecting "Open Services Folder in Explorer" (or Finder, if on a Mac).
Warning! Always be sure to copy files from the Services Drive (preferably to the Documents or Desktop folder). It is absolutely critical that these files are not linked to directly from the drive. If you link to these files from the network drive, you will have service problems.
Some indications of incorrectly linked content are: stuttering playback, broken or lost files, and incorrect or different content than was originally linked.
