I am preparing to sell my LG Ally (I simply prefer a Blackberry). Which files on my SD card must I remove? I'm afraid to delete anything that is necessary. Forgive me if this is a simple question with an obvious answer. Folders on SD card are: agilefusion Android Data DCIM download LOST.DIR media time I deleted my photos out of the media folder but didn't know if I needed to keep the folder itself. The download and data folders are also empty. Thanks for any help you can provide.
