Can we load maps and assets which exist outside of Project/Content folder

Hi,
This is an extension of previous question posted “Can I Reference an Asset from outside the Content folder? - Platform & Builds - Epic Developer Community Forums

My question is similar, i want to know whether it is possible to use assets and maps saved outside of the game/Content/ folder at run time.

If we can use the textures and material assets that are exist in Engine/Content/ folder in our project, why cant we use assets that exist some where on hard disk.
