In my SD card I have a folder that contains all my custom icons. I did not want them showing up in the gallery so I used the '.nomedia' blank file method to hide them. I have used this method before so I know it works fine. But this time it has only partially hidden them. The gallery still has an album but it contains unknown files. I tried clearing the gallery cache but that did not help. Would clearing the gallery data help? Would that make it find all the media files again?
