I have a huge map image (8192x6144px) which I'd like to display at scales ranging from 1x to 0.1x. At 1x this is about 24 mb using PVR 4-bpp compression--a little too much.

Hey all, I have a selector that searches the mainBundle for all .aif files, and allows the user to select them. This works fine, but then I removed some of the files from the project and folder, yet they did not disappear.
