I\'m working on some file in my sublime text 2 editor, and I want to open a folder in which that file resides.
I know there is a 2 step procedure to do this already
This worked for me: assuming you have opened the file whose enclosing folder you want to open, use the Menu > Project > Add Folder To Project command.
Menu > Project > Add Folder To Project
A new window should open with the enclosing folder. Just click 'Open' and you're done!
