I have an 8gb SD card which it seems like out of no where got full. Thinking it was normal, I deleted a lot of MP3s and cleared all of my pictures (that's all I keep on the card) and got it to where I had 6gb of free space. Come today and I couldn't even download a small PDF because it says there's no more room. I just checked my pictures and they're a couple hundred MBs while the MP3s are still 2gbs. What's the best way of seeing what is taking up the space without having to plug the phone in to the comp and check the properties of every folder on the card?
