I have looked at related posts and none seem to address my issue. I had my MicroSD card filled to the brim with video files. I deleted these to make room for new movies, but the space was not freed up. The files are gone but the space is not returned. I am using Mac OS X 10.6.3 if that helps any. Any help would be greatly appreciated. I would like to do it without formatting the MicroSD card every time I want to add stuff because I will lose my apps. Thanks in advance.
