For people who wish to move the folder path of UE_4.25 again, here’s the guide i have tested with and it works, hoping that it can save you all some time.
- Close Epic Games Launcher.
- BACKUP your current engine folder (eg. UE_4.25) to anywhere else first (i prefer to back it up with Winrar in case your installation fail or Unreal Engine deleted your files)
- Open Epic Games Launcher again, uninstall the engine version 4.25.
- Close Epic Games Launcher.
- Open Epic Games Launcher again, install engine version 4.25.
- Let the installation load for awhile until downloading started.
- Pause the download and close Epic Games Launcher (there will be a prompt asking you to cancel installation, press Confirm).
- Look for a folder called .egstore in the latest downloaded engine folder path (eg. C:\Program Files (x86)\Epic Games\UE_4.25.egstore)
- Delete a folder called bps.
- Copy everything from your original engine folder to (C:\Program Files (x86)\Epic Games\UE_4.25) **EXCEPT **a folder called .egstore.
- Open Epic Games Launcher again and click Resume.
- Let the installation and verification run, it should be good to go.
Note: The **Pending **folder in **.egstore **folder is the one decides whether you can resume your installation or not.
