I don't know what these are. All I've found online is a few posts where
the writers are speculating these usenet index files and the rar
archives with the cryptic names may be an attempt to thwart the people
who send out DMCA takedown demands to usenet indexing sites. This
approach would make the MPAA have to download the file before they could
find out what's in it. This would be a lot slower than looking at
something like doctor.who.s07e10.720p.mkv and knowing instantly what it
is. I guess the could be backup files. I hadn't thought of that.
Encrypt your data in rar files, include lots of par2 files and post your
backup to usenet. A usenet account can be had for $10 or $20 a month
and the backups are good for several years. If the usenet server you
pick goes out of business, sign up with another and get access to your data.
I think I'll download one of these rar files and see if I can find out
what's in it.

Well, they do or must have such - a post can't exist without it.
Excerpt:
Types of newsgroups [edit
<http://en.wikipedia.org/w/index.php?title=Usenet_newsgroup&action=edit§ion=1>]
Newsgroups generally come in either of two types, binary or text.
There is no technical difference between the two, but the naming
differentiation allows users and servers with limited facilities to
minimize network bandwidth usage. Generally, Usenet conventions and
rules are enacted with the primary intention of minimizing the overall
amount of network traffic and resource usage. Typically, the newsgroup
is focused on a particular topic of interest. Some newsgroups allow
the posting of messages on a wide variety of themes, regarding
anything a member chooses to discuss as on-topic
<http://en.wikipedia.org/wiki/On-topic>, while others keep more
strictly to their particular subject, frowning on off-topic
<http://en.wikipedia.org/wiki/Off-topic> postings. The news admin (the
administrator of a news server
<http://en.wikipedia.org/wiki/News_server>) decides how long articles
are kept on his server before being expired (deleted). Different
servers will have different retention times for the same newsgroup;
some may keep articles for as little as one or two weeks, others may
hold them for many months. Some admins keep articles in local or
technical newsgroups around longer than articles in other newsgroups.
Back when the early community was the pioneering computer society, the
common habit seen with many articles was a notice at the end disclosed
if the author was free of, or had a conflict of interest, or had any
financial motive, or axe to grind, in posting about any product or
issue. This is seen much less now, and the reader must read
skeptically, just like in society, besides all the privacy or phishing
<http://en.wikipedia.org/wiki/Phishing> issues.
There are currently well over 110,000 Usenet newsgroups, but only
20,000 or so of those are active.^[/citation needed
<http://en.wikipedia.org/wiki/Wikipedia:Citation_needed>/] Newsgroups
vary in popularity, with some newsgroups only getting a few posts a
month while others get several hundred (and in a few cases a couple of
thousand) messages a day.
Non-Usenet newsgroups are possible and do occur, as private
individuals or organizations set up their own NNTP servers. Examples
include the newsgroupsMicrosoft
<http://en.wikipedia.org/wiki/Microsoft> runs to allow peer-to-peer
support of their products and those at news://news.grc.com.
Binary newsgroups [edit
<http://en.wikipedia.org/w/index.php?title=Usenet_newsgroup&action=edit§ion=2>]
While newsgroups were not created with the intention of distributing
binary files, they have proven to be quite effective for this. Because
of the way they work, a file uploaded once will be spread and can then
be downloaded by an unlimited number of users. More useful is that
every user is drawing on the bandwidth of his or her own news server.
This means that unlike P2P
<http://en.wikipedia.org/wiki/Peer-to-peer> technology, the user's
download speed is under his or her own control, as opposed to under
the willingness of other people to share files. In fact, this is
another benefit of newsgroups: it is usually not expected that users
share. If every user makes uploads then the servers would be flooded;
thus it is acceptable and often encouraged for users to just leech
<http://en.wikipedia.org/wiki/Leech_%28computing%29>.
There were originally a number of obstacles to the transmission of
binary files over Usenet. First, Usenet was designed with the
transmission of text in mind. Consequently, for a long period of time,
it was impossible to send binary data as it was. So, a workaround,
Uuencode <http://en.wikipedia.org/wiki/Uuencode> (and later on Base64
<http://en.wikipedia.org/wiki/Base64> and yEnc
<http://en.wikipedia.org/wiki/YEnc>), was developed which mapped the
binary data from the files to be transmitted (e.g. sound or video
files) to text characters which would survive transmission over
Usenet. At the receiver's end, the data needed to be decoded by the
user's news client <http://en.wikipedia.org/wiki/News_client>.
Additionally, there was a limit on the size of individual posts such
that large files could not be sent as single posts. To get around
this, Newsreaders were developed which were able to split long files
into several posts. Intelligent newsreaders at the other end could
then automatically group such split files into single files, allowing
the user to easily retrieve the file. These advances have meant that
Usenet is used to send and receive many terabytes
<http://en.wikipedia.org/wiki/Terabytes> of files per day.
There are two main issues that pose problems for transmitting binary
files over newsgroups. The first is completion rates
<http://en.wikipedia.org/wiki/Completion_rate> and the other is
retention rates <http://en.wikipedia.org/wiki/Retention_rate>. The
business of premium news servers
<http://en.wikipedia.org/wiki/News_server> is generated primarily on
their ability to offer superior completion and retention rates, as
well as their ability to offer very fast connections to users.
Completion rates are significant when users wish to download large
files that are split into pieces; if any one piece is missing, it is
impossible to successfully download and reassemble the desired file.
To work around the problem, a redundancy scheme known as PAR
<http://en.wikipedia.org/wiki/Parchive> is commonly used.
A number of websites exist for the purpose of keeping an index of the
files posted to binary newsgroups.
Major NSPs have a retention time of more than 1700 days.^[1]
<http://en.wikipedia.org/wiki/Usenet_newsgroup#cite_note-1> This
results in more than 9 petabytes
<http://en.wikipedia.org/wiki/Petabyte> (9000 terabytes
<http://en.wikipedia.org/wiki/Terabyte>) of storage.^[2]
<http://en.wikipedia.org/wiki/Usenet_newsgroup#cite_note-2>
In part because of such long retention times, as well as growing
Internetupload
<http://en.wikipedia.org/wiki/Uploading_and_downloading>speeds, Usenet
is also used by individual users to storebackup
<http://en.wikipedia.org/wiki/Backup>data in a practice called/Usenet
backup/, or uBackup.^[3]
<http://en.wikipedia.org/wiki/Usenet_newsgroup#cite_note-3> While
commercial providers offer moreeasy to use
<http://en.wikipedia.org/wiki/Ease_of_use>online backup services
<http://en.wikipedia.org/wiki/List_of_online_backup_services>, storing
data on Usenet is free of charge (although access to Usenet itself may
not be). The method requires the user tomanually select, prepare and
upload the data
<http://en.wikipedia.org/wiki/Backup#Data_repository_models>. Because
anyone can potentially download the backup files, the data is
typicallyencrypted <http://en.wikipedia.org/wiki/Encryption>. After
the files are uploaded, the uploader does not have any control over
them; the files are automatically copied to all Usenet providers, so
there will be multiple copies of it spread over different geographical
locations around the world.
Are you sure these are not just backup files?

The poster is always, as far as I can tell
NzbIndexder@followed by the name of the group they're posted
in. Forexample: [email protected]
<mailto:[email protected]>
Then I'll find posts with names like
this:Vv0smCatI4I08qoLd815.part170.rar
I've seen people here give me tips on usenet harvesting so
I'll ask if any of you how I can use these usenet
indexposts? I've read that some usenet indexing sites
havebeen forced to shut down. I'm guessing these files are
anattempt to get around the people who are trying to shutdown
the usenet indexing sites. The names of the rar files give
no clue as to what's in them. If you don't know ahead of
time what's in these files the only way to find out is to
download one, which may be several GB in size.
Does anyone know how to use these files?
Thanks
Derek
