I've noticed lately that a lot lately that files I've downloaded to my Droid, mostly PDFs though it's happened to a spreadsheet or two, will be viewable at the time, but corrupted and unable to open when I reentered the apparently to view a given file at a later time. Is this something I'm missing, like not closing the file for example? Would that even make a difference?
Also, how do I delete the files I can't open? I can't find them with Astro, but I don't really know where to look. Is there a way to do so within D2G?
