if your sending to this site then you probably have the first tool to get into any filr and microsoft gave it to you. it is a litel thing called edit.com in your dos folder.and you will start to learn what is in a .cr2, or .rsr or px3 file. it is the base look see program of them all.the other things, go to the utility section in free stuff or equiv depending the site and grab what you need. thats what its there for. if your in a third world countrey then go see the consulat and bug them for a while and you might get one (a program) that is better than buy.
