Not a problem, unarchiving media is easy! First, click on "Archived" under your media library.
This will bring you to all of your archived media. Next, click on the file you would like to remove from the Archive. When the file pops up, scroll to the bottom and click on Unarchive. This will take your file from "Archived" to "All."
And that's it! You're good to go and your file is ready to be attached to any application.
