CCleaner. in CCleaner Bug Reporting Posted June 26, 2006 http://en.wikipedia.org/wiki/Index.dat[/url] Thanks again Tony. 1) Although "y" (nor Y,N,n,A,or a) didn't work for me, the biggest mystery was all the other keys on my keyboard being "dead" when I tried to type anything else.!! 2) A very interesting link and I would still advocate an anti-index.dat attitude. All The Best, Haba. PS. Don't know what happened to the quote.!! 1) Should read " As for your questions, "y" should really work, just like it does in the batch command: "DELTREE /y" Not sure what happened there". 2) Should read "And here's some reading on index.dat files: http://en.wikipedia.org/wiki/Index.dat"
