I don't exactly know what this would be under but I downloaded this .rar file and it had some files that ended in .001, .002, to .014. There is also a .sfv file and a .acl file. What do I do with these? Thanks.
Right click on the rar file and simply extract as you normally would (if there is no RAR file right click on the 001 file).
Praetor is right, a .rar file always extracts to multiple .rar files and other files (unless you downloaded the multiple files individually) As Praetor said, extract any 'one' of the multiple .rar files to another folder and the extraction process will automatically unpack all the other files within.
One minor addition/assumption.... just make sure the RAR files are all in one folder before you extract
