Remove projects from launcher libary

I’d like to remove projects from the launcher without deleting them. I know that @TMEK has provided a solution for this once you open an engine but I’m looking to do this for the longer list that shows when you click on the library tag on the launcher. I’ve moved these files to an archive and don’t want the clutter.

Can’t you just change the location of the projects that you no longer want to see / show?
So removing them from the project folder and save it in a different location?

You remove them by deleting them. Copy the file to a backup location. Then right click and select the delete. This will delete the original files and remove the item from My Projects.
