I am not able to transfer some edited photos to a usb or upload to Facebook (from PSE 10). I have tried saving a copy as a jpeg but this is not working for me either. It says there is no room when in fact there is plenty and the next, non-edited photo I transfer goes just fine.
You might get a little farther if you gave us more explanation of what you're trying to do and exactly what is failing.
Which application are you using (Elements Editor or Elements Organizer)?
What does a USB drive have to do with Facebook?
Where are you transferring the file when you are told that the drive has no more space available?
What does the edited or non-edited status of the file have to do with this? (because a file is just a file, the history should not matter)
