Question.

I have downloaded a research program from the Internet and it came in a rar file. When I open this rar file it has about 50 files that start with:

rzr-rsh.xxx where the xxx is 000 ~ 050

How do I go about getting the exe / setup file for this research program?

Thanks!

Try opening up the first rar file, sometimes the file will show up in there (even though it is split between the other rar files). If that's the case, try extracting it out of there.

File Splitters

File Splitters are applications that split files into smaller pieces. Unlike RAR, they usually don't apply any kind of compression to the file, they just split it. If you split a file named TEST.MPG, you will receive TEST.MPG.000, TEST.MPG.001, TEST.MPG.002, and so on. To reunite the file, you'll usually need a file splitter application (needn't be the one used for splitting), but you can also reunite the parts without a file splitter.

Some file splitters create a .BAT file, that users only have to place into the same directory as the parts and then run it. It will reunite all files automatically. Sometimes such a .BAT file is included with a post, sometimes it isn't. In case you don't see any .BAT file, it's no real problem as you can create such a .BAT file yourself.

Place all files into one directory and create a new .BAT file there (e.g. create RUNME.BAT). Now open this BAT file in an editor (e.g. Notepad). For this example I assume the files are named TEST.MPG.xxx (xxx = a number). The BAT file would look the following way:
copy /b "TEST.MPG.000" "TEST.MPG"
copy /b "TEST.MPG" + "TEST.MPG.001"
copy /b "TEST.MPG" + "TEST.MPG.002"
copy /b "TEST.MPG" + "TEST.MPG.003"
copy /b "TEST.MPG" + "TEST.MPG.004"
copy /b "TEST.MPG" + "TEST.MPG.005"
copy /b "TEST.MPG" + "TEST.MPG.006"

Continue according to this scheme for all parts.
Important: Please notice that the first line differs from all the other lines. Further please notice that the file names are always in quotation marks, which aren't always necessary, but in general it's better to always use them (in case of file names that contain spaces, it IS necessary). Once you run the file, it might take some time so please be patient.

There are two easier ways, which don't always work. If you have to reunite only very little files, you can try to reunite them within a single line:
copy /b "TEST.MPG.000" + "TEST.MPG.001" "TEST.MPG"

But if the line gets too long, it won't work. What the maximum line length is depends on your system and how it is configured. If you saved the files in the correct order (first .000, second.001, third .002, etc.), you may also try the following:
copy /b TEST.MPG.* TEST.MPG

But it only works if you really stored the files in the correct order, as the parts will be reunited in the order you saved them to disc and if that order is wrong, they will be reunited incorrectly. That has something to do with the way how Windows saves files (and once again shows us, why Windows is not a real Operating System, but just some crappy application that pretends to be an Operating System). You should try this last solution anyhow, because if it works, you saved yourself a lot of work and if it doesn't, you can simply delete TEST.MPG and try one of the other two possibilities.

Linux user simply type
cat TEST.MPG.* > TEST.MPG

and it will always work, regardless in which order you saved the files.

Open up .000 with your unrar program.

Man, brings back memories of Junior High School: me carrying around a box with dozens of 3.5" floppies. Took forever to create a set and then reunite it on another machine... but still faster than a transfer from one box to another via dialup.

Almost had an aneurysm burning my first CDR.

I Rember back in the day when usenet acualy was a usefull source of info and not all spam

Nice!

Thank-You everyone; I can now run my research program, and I have a back up copy on CD too!

heck I rember when I got my first 256meg thumb drive and marvled at it's ease of protability. and the real shocker was my first 4gig thumb drive.

well if we're reminiscing about thumb drives now, i remember when i plugged a (very early) 32mb thumb drive into the library computer at my school and the Nazi of a librarian came over and freaked out thinking i was doing all sorts of g4y h4x0r1ngz on her precious dells.

I remember when I DID do g4y h4x0r1ngz on the computers at the library in high school. F8 + dos + delete security software directory = gg. Got busted eventually.

high school computing haxing was easy back in the day...not sure what its like now...just a lot of macs from what i hear..

I rember the mac's at my middle schoole. none of the were locked down and I vividly rember playing with the startup options on one of them a accidentally enabiling the geting started program . neadless to say it promped on reboot to be registered

I kind of doubt that was the result of simple file splitting. 7zip gives those extensions when using its compress and split options, so more than likely it was a split compressed file still, seeing as how opening it with a rar app worked fine. I've never known release groups to use just file splitting techniques on releases, it's always been split archives.
