ArcGIS Pro 3.2.1
[edited]
With a .LYRX file, I can drag the file from File Explorer into [the map or Contents pane] without issue.
However, .MAPX files don't seem to have the same functionality. I get an error when I try to drag and drop a .MAPX file from File Explorer into [the map or Contents pane]:
Error:
Failed to add data: C:\...\Map1.mapx.
Could that functionality be added to .MAPX files too?
I'm aware that I can open the .MAPX file [by right-clicking the map name in] Catalog. But my intuition is to drag the file from File Explorer [into the map or Contents], just like I do with .LYRX files.
