MultiPar is an up-to-date (in development) version that seems portable out of the box (just download the ZIP file). Don't know if it's Stealth or not (though file association is useful).

MultiPar at version
1.2.9.2.
full change log
all downloads
wiki page
MultiPar at
Softpedia
Without system integration (
PAR files association, shell and send to integration)
MultiPar seems to be fully portable- settings saved in INI files inside program folder (
MultiPar.ini and
MultiParShlExt.ini).
MultiPar is an excellent tool and to some extent- unique since all similar programs seem to have been abandoned long time ago. I didn't know it was in the
database- in fact it is still private but I think that it deserves to become public not only because
MultiPar is a well-written program but also because there isn't a single similar utility (which can create and handle
PAR files) in the database.
..
Update
It turned out that
MultiPar.EU is an European unofficial mirror, while the official web-site is
this one. There is also a
forum dedicated to
MultiPar.

Use case
- It seems that the primary use for this program is for saving to long term, offline backups where you don't totally trust the media (e.g. DVDs and tape backup). As the media deteriorates or gets scratched, the PAR data can help recover from minor errors. The program can also verify saved data is unmodified (hashing).
License
- Freeware. Despite so many of the components being open source, the developer of Quick Par is keeping that closed.

MultiPar needs an official forum topic and it should be this one because most posts are about it and not
QuickPar. Comments welcome.
BTW,
QuickPar is still
v0.9.1 and webpage is at
http://www.quickpar.org.uk/.

@Midas
Perhaps this thread should be split into two- the first post for QuickPar and all later ones for MultiPar. About QuickPar- it was abandoned about 8 years ago.
@TP109
Thanks for voting, MultiPar is a unique program- we don't have anything similar in the database and I think that MultiPar deserves to be public.

I did a dramatic entry rewrite. After doing the research to put that text together, I'm pretty sold on the program overall and will probably start using it in concert with large file (50+ megs) distribution.

Off topic
There is a similar program-
PAR Buddy, the
web-site is down, the program is reviewed at
Softpedia but it can't be downloaded from there since the
Softpedia article points at external, no longer available download links. I have
PAR Buddy version
2.80,
x32, does anyone have the
x64 version?

This file-
PARBuddy280_64bit_Setup.exe- has become the holy grail for me, for the first time I fail to find a file I have been looking for, and I exhausted all the resources I could think of. This is a ghost file, I could only find its virtual traces
here and
here. Just because I failed in my quest I decided to ask the community.

Is it that we at TPFC have been misattributing this software and some correction is due or is it in fact a fork of the program, considering Multipar.eu has released
MultiPar v1.2.9.6 (
https://multipar.eu/changelog), while the mentioned author page has a v1.2.8.7 stable (no changelog; official download page at

I can't answer this, as I haven't been using
MultiPar...

I'll switch the entry over to the Japanese page just to be safe. The front-end is closed-source so this isn't a fork situation. As a result, it's important to point to the real author as
gezley suggests.
EDIT: think I figured something out:

Both versions can be found on the .JP site, with 1.2.9.6 listed as the beta version. Just for the time being, I'll link to the beta just because that's what we have now. If anyone thinks we should use the stable version, I have no problem modifying that.
