Restore Project from Cooked Folder

Hello,

recently I made a grave mistake by deleting my whole Content folder. Fortunately, I cooked the whole project beforehand and found all of the assets lying in the Saved Folder. All the textures, materials, BPs are all there.

But when I simply copy them to my actual Content Folder, nothing is being displayed in the content browser and the engine fails to load the Map saying “the map appears to be an asset file”. Why can’t the engine recognise its own asset files? That’s what they are supposed to be, right? I was wondering if there was a way to restore the project from those files, as they are the complete, actual files taking up 20GB of space, so all information should be there.

Thanks in advance.
