Help! – USB & Wi-Fi Flash Drive – Free Document Manager & iFile Explorer App Review

I have a bunch of pics on my phone and it won't let me back it up on iCloud anymore and my computer broke so I can't transfer, so I want to know if I load pics on this app and them delete them from my camera roll if they'll still be on the app after I delete them.
