.nfo

In the Warez scene, .nfo (short for info) is a file name extension for a text file (sometimes called an NFO file) that accompanies and describes a release of pirated software or media. The file contains information such as title, authorship, year and license information. For software, it might contain installation notes. This information is delivered for publishing through digital media to make it searchable on the web as well as within local catalogues and libraries. This type of file is also often found in a demoscene production, where the respective group includes it for credits, contact details, and the software requirements. This type of file has been described as the press release of the warez scene. Info files were ubiquitous, and sometimes required, during the era of the Bulletin Board System (BBS). The file was a stamp of authenticity, explicitly explaining what group released the software and described what modifications (or cracks) were applied if any. Once a software was packaged with an info file and then released, it was then officially owned by that group and no other group could ethically re-release that particular package. A typical warez info file was elaborate and highly decorated, and usually included a large ASCII art logo along with software release and extended warez group information. The most important information is which group, which cracker and which member actually tested and packaged. The designers of these info files, who worked closely or within the warez groups, frequently incorporated extended ASCII characters from the character set code page 437 in the file. As of 2019, info files can still be found in many ZIP archives. In modern-day warez info files, a large ASCII art logo is frequently shown at the top, followed by textual information below.
