Load projects that were backed up during a restore

How do I load projects that were backed up during a restore. They saved in the bak folder in the image but to import a project I need a .proj, .xml or .zip files.

Check how they're organized, you might be able to just .zip the project folder contents and restore that.
I know the ones in the regular gateway backup (projects/) can be extracted out that way but haven't seen the .bak before.

That worked. Thanks
