To hide media in a specific folder from the player apps do this:
- Windows: Open notepad and save an empty file as filename “.nomedia”. Linux: In a terminal window create a file called “.nomedia” by typing “touch .nomedia”.
- Connect your Android phone by USB and copy the file into all folders you wish to hide from the media scan.
The media (music, images and movies) contained in this folder will now be ignored and not show up in your MP3 or movie player on the phone. To access and play them you can use a file manager
