I did erase all from the device main menue after having copied them to my computer, that cleared the remaining files and recovered part of the memory. Then I did reformat from the same menu and recovered the entire memory! ;)

I have the same recorder (Sony ICD B310F) and in playing around with the buttons, I figured out how to ERASE THEM!!!

Go to the file you want to erase
Hold down the menu button (have to do this the entire time ) until you see the word "MODE"
While holding the menu button, press the forward arrow (like FF) and scroll until you see the word "ERASE"
Still holding down the menu button, press the play button.
Your file number will blink along w/ the word "ERASE", press the play button.

You should notice your file numbers decreased by one file. You have successfully erased the file.
