Comment 36 for bug 1026254

One decent existing use-case for this feature is the "baobab" program (that is useful to a broad user-base, not just "power-users"), which helps people see their disk usage, and get rid of unneeded large files. It would also apply to any other application that operates on folders.

Without this feature in Nautilus, a user is forced to (1) locate / remember the name of the baobab program and run it, and (2) select an "open folder" item from within the application and navigate to wherever the desired folder to act on is. This is terribly inefficient in comparison with just right clicking on a folder that you are already viewing in Nautilus. The same would apply to any software that is developed to operate on a folder instead of just a file.

One other argument for this is in terms of consistency -- the way you do something with a file in Nautilus should be consistent with the way you do something with a folder -- then there's less to remember about how to do things.
