#UE4 Error Logs: DoesPackageExist

By November 13, 2019November 15th, 2019No Comments

The past  2 days I’ve been dealing an Unreal Engine Error.  More specifically “DoesPackageExist: DoesPackageExist:FAILED:”None: is not a standard unreal filename or a long path name”

I was unable to package my project as an .exe because the error wouldn’t allow me to since it wasn’t compiling properly.

After reading the error message a couple of times over and searching on forums  I resorted to solving the problem by:

  1. Deleting as assets folder that I had imported into the project through Epic Games


  • The project had some characters that were placed in it from this particular folder. So I tried deleting the project folder.
  • The project still had references to the characters, so I deleted the references in the game world (on the right side of the screen)
  • On restarting UE4, the asset folder was still there!
  •  On inspecting the map in my own levels folder and the map in the FPS map (provided by UE), I found an un-deleted reference to it. So deleted it from there as well!


  1. Delete the assets from the Epic Games library
  2. Delete all instances of the assets from your map
  3. Delete the assets folder


Finally I have an .exe!
