I changed the folder options for to show the file extensions and the file was leotard.gz.crz -so I change it to leotard.gz and windows confirms with t message that im changing the files extension -now the file appears in properties as leotard.gz. So I figure I got it but then I open it in winzip and it still (I dont know how)has it as leotard.crz and it still won't extract -have you used winzip to do this-maybe it only works in powerzip???
