Where does Android expect a user to store their data? My SD card is a jumble of directories created by all the apps that have ever been in my phone. I have no idea what most of them are for. Why isn't there some kind of directory structure in use here? /AppData /UserData /SDCard/AppData /SDCard/AppData/MyBackupPro /SDCard/UserData /SDCard/UserData/AppStorage /SDCard/UserData/AppStorage/MyBackupPro /SDCard/UserData/Music /SDCard/UserData/Ringtones /SDCard/UserData/Downloads ...etc I try to keep my personal stuff (music, wallpaper, photos) all under a "MyData" directoryon the SDCard, but then some apps can't find it - such as the album art downloader that I'm trying to run now.
