Hiding folders in X-plore
On Android, files or folders CAN'T be hidden the same way as you're used on Symbian or desktop PC.
That's because Android runs on Linux base, which has no hidden attribute for files or folders.
Many users, mainly coming from Symbian, expect to be able to hide some files same way as it's possible on Symbian or Windows.
So this won't work. Change your habits. Don't expect X-plore to control what other apps show.
One convenience way of hiding files on Linux (and Android) is to put '.' (dot) in front of file name.
This is respected in many file managers and galleries.
This means to Rename your file or folder, and you can do this yourself - rename your files/folders if you need.
X-plore offers Hide function on local folders, but it works in X-plore only.
Such marked folders are then shown as hidden in X-plore (or not shown, depending on your settings to see hidden files).
And there's one more option for media files, if there's a file .nomedia in a folder, then Android Media scanner won't scan media files in this folder and subfolders, and media files stored here should not show in media players and galleries. "Should" is right word, because Android's Media scanner is buggy, and often won't notice adding/removing this .nomedia file.
Don't complain to X-plore, this is Media Scanner that manages visibility of media files to user.
X-plore now adds/removes this .nomedia file for folders that you mark as hidden. The rest is up to Android system to deal with it and show or not show media files in other apps.
That's it about hiding files and folders under Android.
