According your snapshot both are part of same workspace. Sounds not like moving from one host to another ?
By the way based on your sanpshot one folder is seen as an eclipse project the second not. So obviosuly no way to build or anything else on such second folder.
To import a project please rely on "File > Open Project From File System"
Then be aware depending of way you have created project once import will complete maybe all your project resources are not local to it ...
