I have got all the parts for RAR except one. I have already used all
the PAR2 files.
The missing part of my RAR set is #38 out of 49. The extracted file
will be an AVI.
Is there a way to extract the first 37 parts, join them together and
create the first part of an AVI file?

Yes, unpack RAR with WinRAR http://www.rarsoft.com when WinRAR displays
an error window don't click it away. Use VLC media player
http://www.videolan.org to open and play the not complete unpacked
..avi. VLC media player can play the .avi while still in use by WinRAR
most other media players can't do this and generate an error.

PAR can recover one lost fragment AIUI , RAR also has error correction
but I don't think it can replace an entitre missing volume.
I don't understand why people split files once with RAR and again with
par/yenc
there should be some way to extract the partial conteny you have

If you post a file it will get splitted into parts no matter what.
Furthermore, parts will go missing, so the best option is to post
using a protocol that can decode a file with missing parts, such as
yenc, and to use error recovery encoding, such as par.
I agree that rar (or zip) is unneeded for single files.
Par, however, is extremely useful.

That's only if you use solid mode. If you don't use solid mode, an

Depends on the media file.  Some files have padding because they
didn't have enough data to meet the minimum bitrate requirement, and
are padded to meet that requirement. A lot of older files (MSV1, etc.)
are also quite sub-optimal. So it depends on the file.

Shame if its one file
zips can be recovered RAR cannot.
Simple fact is that makes it dumb to use rar at all. No ifs buts or
maybe's are needed.

your response is complete nonesense by the way.

no rars no pars no splitters no yencs - no problems.

soome file formats use redundant coding so that recovery is possible.

You must be new to Usenet. Parts go missing all the time, and have for
the last two decades.

Right. So considering that rar *does* this, and zip *doesn't*, what
was your point again?

You seem to be (falsely) assuming that there is some kind of
forward error correction on a per-post basis.
Parity archives work on sets of files as a whole, so splitting
has no influence whatsoever.

) rar doen't recover from missing parts, only from small-scale data

And zip doesn't recover from missing parts either, nor does it recover
from small-scale data corruption.
So, could you explain what you mean by 'zips can be recovered' ?
Furthermore, the newest versions of rar *can* include recovery data
for whole missing parts.
