I need to add something to an app's folder which is hidden but even though when I connect my s5 to my computer via a USB cable all the files/folders show up, hidden folders remain hidden. I have allowed all hidden files to be shown on both the s5 and the computer using ES File Explorer on the phone and Folder Options on the computer but still nothing. Driving me crazy. Any ideas? Thanks. FYI, using Marshmalllo 6.01.
