Open up your Gallery app on your Android device. Go ahead; I dare you. Notice a bunch of clutter in there from things you don't want showing up? If you've got a little bit of Android acumen, you are cognisant of the fact that placing a simple .nomedia file in the offending directory will exclude it from showing up in Android's media handlers such as the Gallery and music player. Unfortunately, however, creating or copying a file manually is a bit of a drag.

In order to keep things simple, XDA forum member knox420 has created a wonderful little utility to place (and remove) these aforementioned .nomedia files quite easily.

Here's why:

Many apps create folders on the sd-card and drop their stuff there. Often, they place images as well. Now that Android checks the sd-card for new media from time to time, these folders will be added to the media database and displayed in the stock Gallery app.

Here's how:

Gallery Excluder lists all direct subfolders of '/sdcard' respectively '/mnt/sdcard' and displays them in a list. If an item/folder gets checked there is a '.nomedia' placed in that folder. If the folder gets unchecked the '.nomedia' is removed.

Since it can take a while to have the gallery update you can force a manual update via options menu.

Well, what are you waiting for? Make sure to make your way over to the application thread to get a piece of this yourself!
