Just trying to speed up my computer a bit, and get rid of whatever miscellaeneous stuff I don't need. I used a file recover software, and saw the thousands of files that were still being recognized. I downloaded this tool and ran the erase unused space function to get rid of it. It freed up a gig and a half of space, which is nice. My question is, now when I use the file recover program I still get a lot of files recognized, but now they are 0kb files with "000000000000000..." as their names. Is this how the eraser program is supposed to function, replacing the old files with these new ones?
