Re: What in the heck is a PAR viewer?
Probably some geeky command-line compression format for files like RAR, ACE, and the like.I want to depart this world the same way I arrived; screaming and covered in someone else's blood

Re: What in the heck is a PAR viewer?
The reason I ask, is that people post full music CDs on newsgroups, and along with the MP3 files, there are always a bunch of files that have extensions like par2 and yenc. I wondered what those files are.

PAR files are PARity files. They're extras that allow you to rebuild the set you downloaded if some were damaged or incomplete. QuickPar is the tool you want (it's free).Catapultam habeo. Nisi pecuniam omnem mihi dabis, ad caput tuum saxum immane mittam!

Re: What in the heck is a PAR viewer?
So if the mp3s are all good, then I don't need the PAR stuff?

Re: What in the heck is a PAR viewer?
Oh yeah. I had forgotten about the parity files in newsgroups. Had you mentioned that earlier.... [img]/images/graemlins/laugh.gif[/img]
yenc is definitely a compression format. I've seen it mentioned in my Porn searches [img]/images/graemlins/laugh.gif[/img]
Not surprisingly, people are divided on the issue of using RAR compression or Y-Encoding (yenc), with seemingly bitterly opposed camps - there's always a fuckin anti-Microsoft bitch in the crowd that feels he has to make one that isn't compatable with Outlook Express [img]/images/graemlins/laugh.gif[/img]I want to depart this world the same way I arrived; screaming and covered in someone else's blood

Well, I don't have the ability to open either of those type of files, and if I don't need them, I'm not going to bother downloading and installing a program that reads them.

Actually, RAR and Yenc have nothing to do with each other. RAR is just compression like winzip. Yenc is binary/text conversion.
For newsgroups, large files could be chopped up into smaller pieces so that (pre highspeed era) if you lost your connect, you could restart at the last rar you were disconnected on as opposed to losing connect mid download of a large file (requiring you to start from the beginning again. In the process of files becoming larger, more pieces were being used, and the likelyhood of any one or number of rar parts being corrupted increased, resulting in an unusable complete set of rars.
Par came into play that would, using the entire original set of rars, create some extra data files that could be posted along with rars and used to recreate any missing rar piece. This was to reduce the number of repost requests and bandwidth wasting because everyones news-server may have corrupted different pieces all together, so one par could fix everyones bad rar, even if the piece I had that was bad wasn't the same piece that was bad for someone else.
On Yenc, specifically for newsgroups, all binary files are converted to text, as the usenet is only text. UUencode was always used to do the conversion to and from, but this results in massive overhead. A 5Mb mp3 would wind up being like 8 or 9Mb worth of download in text format before being converted back to binary. And the more posts made, and limited space alotted per newsgroup for this data, would push previously posted files off to oblivion all too soon.
Yenc reduced the conversion overhead significantly so now that same 5Mb mp3 now is only a 5.5Mb download. The result, more files available at one time on a newsgroup, and for longer periods of time.
And Outlook was never made to be used for binary newsgroup access. It works exactly as it was meant to in text only groups.
Get Agent/Free Agent for binaries.
What I don't get is with the the law/MPAA/etc.. chasing P2P/torrents/Napster/WinMX etc when My ISP makes available a guaranteed resource for any file/software/movie/game/etc with full d/l speed, no having to share/upload.
