Delete folders from the SD storage I have a Nexus 4 smartphone and in external storage there are many folders which I believe to be unused and/or empty.

Is it possible to delete them safely? In other words, if I delete an empty folder that is really needed by an app, will it get recreated automatically or will I break the app?
If they are empty, they can be deleted. They will be recreated as needed. Before deleting them, make sure that they really are empty. As in, not even hidden files are there, except for ones like ".nomedia"
