title_body: How do I remove a book from my Sony Reader? I have lots of space left on my Sony Reader (a PRS-T1), but I also have a few books on there that I don't want to read again (or at all). I am trying to figure out how to remove them from the reader using the software that came with it, but I seem to be missing some vital bit of explanation, because I can't seem to take books off of the reader.
  
  Some of the books I want to remove are expired library loans, and some are actual books I have bought and paid for, if that makes any difference. Ideally, I'd like a way to remove multiple titles at once, but if not, one at a time will work too.
upvoted_answer: If you want to remove files from the PRS-T1 you can connect the reader via its USB cable to a computer and have the internal memory available as a USB drive. The TRS-1 shows itself as two USB devices, one named SETTINGS, the other READER.
  The books are normally under READER/BOOKS.
  
  You can just search for, and delete the books with your OS' file browser. 
  
  The device will rebuild the database of available books after disconnecting it from the computer.
  Make sure to properly remove the device, do not just unplug it.
