Just want to move the card contents to the internal storage. I see that the internal storage shows as sdcard and the sd card shows as ext. I'm sure it's something easy.
Haven't hooked up the fone to a computer for mass storage but if you can mount both or use a reader for your d1 card to just copy, that might be as simple as drag and drop.
Just copy the things you want......pics, mp3s, etc....and don't copy the things like backups (useless), ROMS (useless), app directories, etc.... .android_secure, android, lost.dir, etc...
The built in Files apps should be sufficient to move your pictures, music files and such.
