UMAP files can open in UnrealEd. UnrealEd works on Windows. It is for editing Unreal game files. The UMAP file format stores Unreal game maps. 1509 file types can store maps. But most other file types are not compatible with UMAP. Unreal game players use UMAP files. UMAP files show 3D game worlds. UnrealEd opens UMAP files best. Other programs might open UMAP files too. But UnrealEd works best. Some programs convert UMAP files. But UMAP conversion to other formats often does not work.
To open, use UnrealEd. Select “Open Level”. Then choose the UMAP file. If it does not open, manually move the file. Move it to the Content folder in the project.
Windows cannot open UMAP files by default. So choose an app when asked. UnrealEd was created by Epic Games to open these. File Viewer Plus opens 400+ formats too. But UnrealEd fits UMAP files best.

Please let me know if you would like me to modify anything further.
