I have a 4gb SDHC memory card and all of a sudden it shows that it is 95% full (only about 50 mg left). I've gone up and down the directory deleting almost everything I can except my music which is less than 1 gig. I've checked every single folder but cannot account for almost 3 gigs! And I cannot free up anymore space on it to download podcasts etc like I used to.

Any ideas????
