Database Construction from Existing Folders

[rockbo842]

I ran YoutubeDL-Material for a long time before finally getting the MongoDB to work, so I have numerous folders with hundreds of videos and have lost subscription setups multiple times in the past. Now that I have MongoDB working, is there a way to incorporate those existing folders into YoutubeDL-Material so I can access those video in the GUI and also reestablish old subscriptions without having to redownload files?
