So, you got yourself a 32 GB microSD card that you just filled with everything you have on your computer (as far as media in concerned). Everything goes well, but you cannot help and notice that your Class 10 card should be, or at least feel a bit faster than what it is when it comes to loading pictures in your gallery. There are a quite a few guides on how to fix the speed of your SD card, and they will all help, but for this particular reason, there may be a much simpler solution at hand. Normally, the gallery applications for Android will scan your whole device for pictures. This means that along the way, it will pick up icon folders, background folders, thumbnail folders, and anything that is not what you would like to show up in your gallery. For instance, you may have a folder with icons for your current custom theme in the heart of your card. These will be picked up during the scan.
To save you from this annoyance (as well as a few other “unwanted” pics that you may have floating around in your device), there is a very simple fix. Whenever you do not want certain pictures or image files to to show up, all you need to do is simply rename the folder that contains the media with a “period” at the beginning of the name. Android will consider this as a hidden folder and as such, it will not look at it when providing you with the requested pictures. For instance, a folder called private, you will simply need to rename it to .private, and boom! problem solved. Also, you can add an empty file called .nomedia to the containing folder, which will also take care of the issue.
Give it a go and see if this works for you.
