  • I wonder would there be any sure-shot answer for this question. Anyhow, I'd rather prefer to experiment than to seek answer: 1) Take backup always, 2) Rename the folders (not all) to either .folders or something else to see whether stability is maintained. Then delete when you're certain. It's time-consuming but stability is at least assured. Commented May 26, 2015 at 21:21

    @Firelord I think that's a good way to test it, but as you mention, very time-consuming (especially for hundreds of empty folders). I'm hoping that this site provides a way to ask a question and for people to reply with answers derived from their experiences, knowledge, research, or experimentation. No sense in reinventing the wheel! :-) Commented May 26, 2015 at 22:24

    Question might also be: where are those empty folders? If on the SD card, it's pretty safe I'd say (apps should simply re-create them if needed; after all, cards are "removable"). On internal storage I'd rather not give a "general advice". Commented May 26, 2015 at 22:30
  • @Izzy Great question Izzy. I'll update the original question to include those details. Commented May 26, 2015 at 22:34

    And I'm looking forward to answers including internal storage. Am pretty sure @Firelord is correct: if they are really empty, it should be safe. But I wouldn't wonder if some of them simply re-appear ;) Commented May 26, 2015 at 22:38
