yep. an sfv file is a file used to do a crc check against a group of files, verifying their integrity.
(crc - cyclic redundancy check)
(sfv - Simple File Verification)
an sfv is similar to a cue file for example, in that it's just text and you do not need to change any extensions to view it, simply right-click and open with notepad.
anyways, on to the files themselves...
the .001 etc, are .rar volumes. their extensions can vary, from simple sequential numbers as you have, to part#.rar to .r01..
anyways, you need winrar. once you have it, navigate to the folder containing these .001 etc files (when you unpacked the .tar it should have separated them into cd1, etc...but whatever. point is, you have 3 separate 'batches' of rar 'volumes' to extract)
click on the first .001 file, and then click 'extract' in winrar.
do that for all 3 cds. (pay attn to where they get extracted).
these 3 cds likely consist of image files in some format (most commonly bin/cue) you will need a burning program such as nero to burn these. if you need more info on burning cd images, of course post again.
oh, and to take a screenshot, click your 'prtscn' (print screen) button on your keyboard...now it's in your clipboard. open mspaint or photoshop, and paste your clipboard contents into a new file.
there's your screenie
oh, and this is going to computer forum
