SD card nearly full, but can't figure out why

[Vance14]

I did a factory reset so I could use my daughter's old DINC for my son. I thought this would wipe out the SD card as well, but I guess it didn't since it still the folders for her old apps (using Astro File to view the card). The card is showing nearly full, but I am having trouble finding where all the data is so that I can delete it. I have gone through all the folders and I just don't find anything. No pictures, videos, app data, etc.

Where should I be looking?

You could reformat the SD card in the phone settings under Storage. As long as you're sure that there is nothing on it you want. You may want to plug the phone into a PC first and copy everything off just in case.
