I had to wipe a computer and reinstall the operating system and eclipse. i had backed up two of my projects in my working folder for eclipse. i copied those project folder into my new working eclipse folder, but i can't seem to open them. Open project is grayed out. I don't know what file to open to open the whole project like in visual studio I think it was the dsw file for c++. Also these are android java projects. I thought I'd ask here as its a more active forum and the question is not necessarily specific to android but working with eclipse, a common java tool.
