download as file_name.mpg.000, file_name.mpg.001,
etc. How do I view these files?

These file extensions you mention indicate that they are sections
of a larger file named abc.mpg (to use your example). These
sections differ from multi-part binaries where not all the parts
appear and are therefor not downloadable decoded. What you are
downloading *is* 'decoded' but it(they) is(are) still only a portion(s)
of the larger file(s).
They have been 'split' into sections by a program called
"Master Splitter" (MAC version is 'ChunkJoiner' I believe)...
The analogy I've used in the past to describe what these are is to
picture yourself baking a loaf of bread. While all you have is still
flour, water, yeast, and a bread pan,. the loaf (or file) is 'encoded'.
When the bread bakes (or the file downloads) it is 'decoded'.
When the "Master Splitter" program is used it, in effect 'splits' the
loaf of bread (or file) into 'slices' (or sections) of the baked
(decoded) file. A file_name.mpg.000 file (normally about 38 bytes)
is the 'bread pan' that all the ingredients (file sections) are 'baked'
(decoded or re-joined) into. Any section could simply be renamed:
file_name-chapter01.mpg, and so on OR be 're-joined' into the
original larger file again in one of two ways:
[assume that our file had 12 sections plus a 000 and a BAT file]:
Sometimes, a poster will also post a file_name.mpg.BAT file
that contains coding similar to the following:
@Echo Off
Echo.
Echo Creating file_name.mpg from the 12 original pieces.

Echo This may take a while...

Echo.

This BAT file and the commands inside tell your computer to
rejoin all the 'slices' (sections) back into a single larger
file named: file_name.mpg
Some people are a bit leary about downloading 'executable'
file extensions in newsgroups or from otherwise unknown
sources (which is perfectly understandable), so there is a
second method (considerably 'safer' for the downloader) to
rejoin these files. That is to download and install:
Master Splitter 3.5h (latest public version) at either of these:
http://pcworld.com/downloads/file_description/0,fid,5132,00.asp
http://ftp.pcworld.com/pub/new/utilities/file_management/mspt35h.zip
or TomaSoft's *very latest* version: 4.1 i (WinXP-compatible)
on their site at: http://www.tomasoft.com/mswin95.htm
or directly as: http://www.tomasoft.com/mspt32install.exe
or if you prefer a ZIP file: http://www.tomasoft.com/mspt32.zip
By using the 'Master Splitter' program to rejoin the sections,
you only need:
file_name.mpg.000 and all the subsequent numbered sections,
but not the (potentially risky) BAT file.

MAC USERS, PLEASE NOTE:
MAC-related answers in Part III assume that you have QuickTime3 installed.
If you don't, download (Keyword: Apple) and install it ASAP
-- it will save you many headaches!!
QT3 runs on any 68020, 68030, 68040, and PowerPC (PPC) Mac using OS 7 and
above. PPCs need a minimum of 16 megs of RAM; the others need a minimum
of 8 megs of RAM. Of course, the more RAM, the better.
When you download QT3, you will also get a new version of MoviePlayer,
PictureViewer, and the QT Plug-in for use with your browser.
You will need a decoder -- shareware decoders such as UULite and uucdPPC
(for a PowerPC) are available in AOL's software files (click on the
floppy-with-a-magnifying-glass icon in your Toolbar or got to
Keyword: File Search, to MAC library and search for
the word decoder); another good decoder can be found at:
http://www.concentric.net/~Columbin/
You will also need some picture viewing software, such as JPEGViewer (which
also handles GIF and some other formats), GIFConverter (which also handles
JPEG, PICT, and TIFF formats), and GraphicConverter (which handles GIF, PICT,
BMP, JPEG, and some other formats).
Most of these are available in AOL's software files. (BTW, if you use ANY
shareware, PLEASE send the developers a check -- it helps feed them and
inspires them to keep up the good work!).
