Well this is interesting. I plugged my phone into my computer to pull some photos off of it and I just happen to start browsing it via Windows Explorer since the device shows up there. Imagine my surprise when I saw things that were in my Hidden folder show up clear as day. It seems that lock is only at an application level and just browsing the file system it’s there to see.
Does anyone else experience something similar? Is there a note I missed that it’s still be available via other means?
Personally I like the way that this is implemented; makes it easy to download hidden media files onto my Mac. Anyways, if you’re worried about nudes/pr0n being seen by unauthorized parties, I wouldn’t recommend stashing them in your photos library anyways. There are vault-type apps in the App Store that masquerade as note/calculator apps (Calculator# comes to mind) which are more suited to addressing OP’s use case.
