How to keep Workspaces in Blender 2.80 when opening previous version of blender's files? i'd like to use the bmps file from previous version of blender, in blender 2.80 as latest version.

but, when it's opened, blender 2.80 lost every interface layout it usually has. especially those new workspaces as tabs on top of the screen.

is there a way to keep blender 2.80's interface layout -especially the workspaces- whenever we open previous version of blender files?
Start new project using General preset

File -> Open .., locate your .blend, but before you open the file, uncheck the Load UI option





Your old .blend should be opened using the General preset UI, so the workspace should be there
