I have no idea if you're being facecious so I'll humor you.
Warez is a term commonly used for pirated software. Most warez now are packed in multipart archives for easier transmission over the 'net.
.nfo = iNFO file. This text file documents things such as the warez group/members who were involved in cracking/distributing said program. Also may contain release notes and a serial number.
.sfv = CRC verification file. Using the proper program one can compare the CRCs of the downloaded archives with the original CRC checksums in the SFV file, as they often get corrupted.
.r## = where ## is replaced by a number. Files packed by RAR compression, one of the more commonly used compression programs for warez archives, due to its multipart archive handling ability, speed, and reliablilty.
Sometimes also seen as .### files or even .s## if it's a really large archive (from r01-r99 to s01....)
