How to hide files (such as video or photo files) in iPhone?
I don't know. Perhaps an app or something?
I downloaded KeepSafe on my android (though haven't used it much yet). I believe there's an iPhone version of the app too. If you try it out, post back and let us know!
You could always use compression utilities and/or change the file extension of the name. Without the correct file extension, the OS/app would depend solely on the file header for handling the file. However this would only trick computer users without education in programming. To hide file from everyone, you would need to use encryption software.
Best file encryption software
Droplock 1.0 sounds interesting and it is free.
@cliffordcooley: Thank you for your reply. I don't want to involve myself with a non-simple process just to have my files hidden! What I need is a iOS app which does its work simple and safe. Be sure I appreciate your try to help me.
