Introduction
These files are made by groups that release wazez. Each of the 3 files have a specific purpose. The .nfo & .diz files are included with almost every release that a warez group will make. The .sfv file

.nfo files
.nfo (aka .information) file contains information about a release.

Theses are often called (group name).nfo, (release name).nfo or (short group name)-(short release name).nfo

They contain very usefull information about the file(s) that you have downloaded. They could contain one/all of the following:
- Serial codes
- URL's
- Instuctions for cracks
- Anything else

One of the mose intoresting things about these files is the groups ASCII art logos. Making a good logo is a highly skilled job. These files are also used for the group to release news or information about the group (its members/recruitment/closure/etc).

To view these files, people normally use notepad (just drag it in). I would reccomend using the d*mn NFO Viewer:

.diz files
.diz file contains a short description about a release

These are normally called file_id.diz

They normally contain information about the following:
- Release version
- The group that released it
- The date released
- Protection cracked(?)

Normally most people dont read these, as most (if not all) of the information provided in them is in the .nfo file, but sometimes they do contain more information, or even if there is no .nfo file.

These files also contain a small amount of ASCII art, but just a very small logo.

To view these files, people normally use notepad (just drag it in). I would also reccomend using the d*mn NFO Viewer:

.sfv files
.sfv contains the CRC32 checksums for a (usually large) release of file(s)

Theses are normally called (short group name)-(short release name).sfv

When a group releases a large number of files, you may sometimes get one of the following:
- Incomplete files
- Corrupt files
- Missing files

This is where the .sfv file comes in. Using a sfv file checker, you can make sure all of the files you downloaded are complete, non-corrupt and all there! Just load up the .sfv file in the sfv checker and click verify!

To check the files, I would reccomend using the FlashSFV checker:
