So I downloaded some pdfs and a flv file from a computer to the Nexus through a USB cable. The "send to" said Nexus 7. But then I couldn't find it, and it wasn't under downloads? Later I did find the files, but ONLY through my Moon+ reader...even then it was just through clicking around "local files", the pdfs hadn't shown up on my Moon bookshelf. Even the FLV file(from Youtube) showed up, though obviously I can't get it to play. Where should I have looked for these? I don't think I need to look to Moon+ to find my USB downloaded files, especially non-book files, and especially since I may switch from Moon+. So..uh..how do I find these assorted files in the future? Also, as a secondary thing...Moon+ gave me a message saying it doesn't do PDF because I don't have the Pro version...but then in my files I found a red icon that said "pdf reader"...what was that reader a part of, originally?
