I have some files in a folder on my external MicroSD card. They show up in Gallery. If I delete them, they show up again the next time the Acer is powered down and then powered up. I read in another forum that if I were to put a blank file named ".nomedia" in the folder, it would hide the files when Gallery scans the external sd card on power up. It doesn't work for me. I am looking for your comments and your experience with hiding files and folders using a .nomedia file.
