FILE_ID.DIZ

SysOps could add a common third-party script written in PPL, called "DIZ/2-PCB"[4] that would process, rewrite, verify, and format DIZ files from archives as they were uploaded to a BBS.

The software would extract the archive, examine the contents, compile a report, import the DIZ description file and then format it according to your liking.

During this time, it was usual practice to add additional lines to the description, such as ads exclaiming the source of the uploaded BBS.

Even since the decline of the dial-up bulletin board system, FILE_ID.DIZ files are still utilized by the warez scene in their releases of unlicensed software.

[5] While real-world use among BBSs varied, with the NPD world and even different BBS brands coming up with expanded versions, the official format is: Plain, 7-bit ASCII text, each line no more than 45 characters wide.
