-A QWK packet filename is normally of the form: ''//​ID//​.QWK''​ (or ''//​ID//​.qwk''​),​ where //ID// is the unique ​QWK identifier (up to 8 valid MS-DOS filename characters, starting with an alphabetic character) of the system from where the messages were downloaded (received).+A QWK packet filename is normally of the form: ''//​ID//​.QWK''​ (or ''//​ID//​.qwk''​),​ where //ID// is the unique identifier (up to 8 valid MS-DOS filename characters, starting with an alphabetic character) of the system from where the messages were downloaded (received). This //ID// is commonly referred to as the "BBS ID" or "BOARD ID" in original QWK specifications and in Synchronet, often referred to as the system "​QWK-ID"​ or "​QWKnet ID".
  
 Similarly, a QWK Reply (REP) Packet filename is normally ''//​ID//​.REP''​ (or ''//​ID//​.rep''​) where //ID// is the QWK-ID of the destination system for which the REP packet is to be sent (uploaded). Similarly, a QWK Reply (REP) Packet filename is normally ''//​ID//​.REP''​ (or ''//​ID//​.rep''​) where //ID// is the QWK-ID of the destination system for which the REP packet is to be sent (uploaded).

 +==== VOTING.DAT ====
 +
 +The ''​VOTING.DAT''​ file is a more recent addition to the QWK packet format (introduced with Synchronet v3.17) and it contains information about message-based voting:
 +  * Polls
 +  * Poll-closures
 +  * Ballots (votes on polls)
 +  * Message up/​down-votes
 +
 +Very similar to the ''​HEADERS.DAT''​ file, the ''​VOTING.DAT''​ file is a text file (with CRLF or LF-terminated lines), in [[:​config:​ini_files|.ini file format]]. ​ A vote-message header block is identified in a QWK //header block// with a //Message Status// value of "''​V''"​ (ASCII 86). The vote section of interest is located in the ''​VOTING.DAT''​ file by first locating the section with the corresponding //header block// byte-offset in hexadecimal (e.g. ''​[f00]''​),​ and then immediately following that section label, will be another section that identifies the //type// of vote message and this section will contain the relevant key/value pairs:
 +
 +^ Section ​         ^ Description ​  ^
 +| ''​[poll:<​id>​]'' ​ | A posted poll with unique message-ID, //id// |
 +| ''​[vote:<​id>​]'' ​ | A posted vote with unique message-ID, //id// |
 +| ''​[close:<​id>​]''​ | The closure of previously posted poll |
 +
 +=== Polls ===
 +A ''​VOTING.DAT''​ poll section (''​[poll:<//​id//>​]''​) may contain the following keys/​values:​
 +
 +| Subject ​         | The polling subject/​question/​summary |
 +| Sender ​          | The name of the pollster |
 +| Conference ​      | The conference number on the target system |
 +| MaxVotes ​        | Maximum number of votes per ballot for this poll (between 1 and 16) |
 +| Results ​         | Visibility of voting results (0=voters, 1=open, 2=closed, 3=secret) |
 +| Comment//​n// ​    | Comment line (0+) to display before available answers (optional) |
 +| PollAnswer//​n// ​ | Available answer (0+) to this poll |
 +
 +A poll is closed by a subsequent ''​[close:<​id>​]''​ vote-message-section which may occur at any later point in time (e.g. even in later QWK packets, received weeks or months later) and once discovered should mark the original poll (identified with the //​In-Reply-To//​ key value) as unavailable for new ballot submissions.
 +
 +=== Ballots ===
 +Ballot message sections are identified by a ''​[vote:<//​id//>​]''​ section. There are 2 possible types of ballots:
 +  - Poll Ballots: contain a "​Votes"​ key
 +  - Message Ballots: contain an "​UpVote = true" or a "​DownVote = true" key/value pair
 +
 +Poll ballots are to be applied to the open-poll referenced by the "​In-Reply-To"​ value. If the poll has been closed, then the ballot is ignored. The "​Votes"​ key value is a bit-field (normally in hexadecimal representation with "​0x"​ prefix), indicating which vote options the voter has selected (bit-0 = PollAnswer0,​ bit-1 = PollAnswer1,​ etc.).
 +
 +Message ballots are simply up/​down-votes to be applied to a message'​s popularity score. The message being voted on is referenced by the "​In-Reply-To"​ message-ID value. If the referenced message doesn'​t exist, the vote is ignored. The "​Sender"​ key/value identifies the voter. Messages are never closed to new ballots, but voters should not be allowed to submit more than one ballot per message. ​

-The ''​.NDX''​ (index) files contained in QWK packets are of a notoriously bad format. These files contain byte offsets into the ''​MESSAGES.DAT''​ file, which is fine. But these offsets are stored as 32-bit real numbers in an obsolete "​Microsoft Binary Format"​. Additionally,​ each record ​contain ​a conference number, but that conference number is only 8-bit, limiting its usefulness to only 256 possible message areas.+The ''​.NDX''​ (index) files contained in QWK packets are of a notoriously bad format.

 +==== Conference Names ====
 +
 +The message area (conference) names included in the ''​CONTROL.DAT''​ file are only used for reader information/​display purposes. The conference *numbers* are references used to identify specific message areas between the reader (or QWKnet node) and the host/hub BBS.
 +
 +=== Length ===
 +According to "QWK Mail Packet File Layout"​ (qwklay) by Patrick Y. Lee (version 1.6 - December 19, 1992), the conference names are limited to "13 characters or less".
 +
 +According to "The Mysterious QWK-File Format"​ by Jeffery Foy (April 25, 1991), the conference names are limited to "10 characters or less".
 +
 +According to "QWKE Specifications 1.02" by Peter Rocca, "​conference area names are no longer limited to 13 characters, they are limited to 255 characters now [in QWKE]"​.
