the original Notepad, copy it elsewhere but don't move or rename it, because Windows will redirect the File Types to the renamed/moved program).
Another excellent text editor mainly meant for coders is EditPlus (shareware), but it has too many functions to be considered a simple Notepad replacement, so I'd rather
install it as a second text editor.</p>
<p>However, once you have it in your text editor, delete all the lines which aren't part of the UUencoded file (everything above the "begin" line and below the "end" line) and
save it to disk with the name you want. Now you can decode it with Shell Decode Extension or Aladdin Expander. Remember to delete the UUencoded file you saved after
decoding it, for it will be only a waste of space on your hard disk.</p>
<p>If the file you are downloading has been UUencoded and then split in multiple chunks, it may happen that single chunks doesn't have the "begin" and the "end" lines. In this
case, after you have deleted all the useless lines, leaving only the ones that begin with a "M", manually add the begin/end lines, as in the following example:</p>
<blockquote>
<pre>
begin 644 File2
M;2XN+BXN+R\N+B\O+BXN+BXN+R\N+B\O+BXO+RXO+RXN+B\ON+B\O+BXN
M"AM;-#LV2"`@("`@+R`@7`H;6S$[,3%("AM;,CLQ,4@@("`@<("\*&ULS
end</pre>
</blockquote>
<p>If you have several chunks of a large files on your hard disk, now it's time to rejoin them. You can do that with a tool such as MasterSplitter, or manually, from the MS-DOS
command line.
In this case you can use the COPY command like in the following example:</p>
<blockquote>
<p>COPY /B File1+File2+File3+File4+FileN DestFile.ext</p>
</blockquote>
<p>Where DestFile.ext is the name of the destination file name with the appropriate extension (.MPG for MPEG movies, .MP3 for MP3 audio files, .JPG or .GIF for pictures,
and so on...)</p>
<p>The option /B is necessary because you are joining Binary files. If you try to join binary files without the /B option, they will be treated as ASCII (pure text) files, and the
copy process will end as soon as the computer will meet a byte with a value of 0, because it will consider it as an End-Of-File (EOF) marker.</p>
<p>If you have several chuncks and you can't put all of their names in a single MS-DOS command line (there's a limit of 127 characters for a single command line), you'd better
join them in larger chunks first, as in the following example:</p>
<blockquote>
<p>COPY /B File1+File2+File3+File4+File5+File6 File1-6<br>
COPY /B File7+File8+File9+File10+File11+File12 File7-12<br><br>
COPY /B File1-6+File7-12 TheMovie.mpg</p>
</blockquote>
<p>If there are some missing chunks, you can post a message asking to the original poster or to someone else who got all the posts, to post the missing chunks again. It
would be nice to have a second newsgroup dedicated only to reposts (a kind of "subnewsgroup"), to don't bother people that got all the parts of the file.
Before to ask, you can try to open that newsgroup from another NNTP server. Since news posts are passed from a server to another, it may happen that your server didn't
get all the posts, but you could find them in another one which has a better "feed" (it gets posts from more newsservers) and a longer history (it keeps old posts for a longer
time).</p>
<p>However, if you can't get all the chunks but the file you were downloading is an MPEG movie, still you can join the chunks you got, if you have at least the first chunk which
contains the MPEG header information. You'll notice some weird effects when two non contiguos chunks join.
Another interesting peculiarity of MPEG files is that you can view them during the downloading. When you open a message containing a MPEG video, stop it as soon as
the link with its file name appear (on Netscape), then right click on the link and save it to disk, so that the file will be saved directly from the Internet to the disk.
Now you can make a copy of the file (click on the file name, then press CTRL+C followed by CTRL+V) and launch it while the rest of the file is still to be downloaded.
This is useful to see if the video you are downloading is actually what you expect, rather than a video you already have with a different name, spam, or something that could
be inconvenient for you.<br>
To see at least a frame of the MPEG video, you should wait until you got at least the first 35Kb (actually it depends from the width/height, color depth and resolution of the
video), while if you want to have a more precise idea of the first second of animation, you should wait until you got 75/100Kb.
The same peculiarity apply to MP3 audio files and also to JPEG images.</p>
<p>If the file you have downloaded is an executable file, DELETE IT AT ONCE. Never run executable program files downloaded from a newsgroup. They are VERY likely to be
trojans or viruses (especially if the program was posted in a newsgroup in which are expressed unpopular ideas). Even if you trust the sender, you can't be sure if instead is
someone who forged his identity.<br>
A trojan can format your hard disk, work as a hidden server that keeps a "back door" open to intruders, or send your e-mail address and other personal information to
someone else on the Internet, if you are online, or next time you are online.
If for some reason you think you have absolutely to try that file, and you can't download it from somewhere else at least check it with an Antivirus such as McAfee before,
which however is a good thing to do for any executable file you downloaded from the Internet, or more specifically from a website you've never been before.</p>
<h3>HOW TO VIEW A FILE DOWNLOADED FROM A NEWSGROUP</h3>
<p>If the file is compressed, you have to decompress it first.
There are many compression formats but most common one is ZIP that might be associated with other kind of compressions.
However the extension of the file will look like .ZIP, .GZIP, or .TAR.ZIP . WinZip can handle them all, and if you installed the WinZip shell extension you can right click on
the file and choose Extract to... from the context menu.
For more compression types you can try Aladdin Expander, which also handles typical Mac compressed files such as .HQX or .SIT (StuffIt).</p>
<p>Now that you have uncompressed the file, you can open it.</p>
<p>Microsoft Windows MediaPlayer handles almost all the audio/video formats. Be sure to have the latest version installed. Another freeware alternative is TornaPlayer.
If the file is an MP3 you may want to use a better and most specific player as WinAmp.</p>
<p>Pictures in almost any format can be opened with ACD-See (shareware) or IrfanView (freeware). For more (and uncommon) graphic formats you can try a professional
application as Corel Photo-Paint. With PhotoPaint you can also edit pictures to adjust colors, contrast, or sharpness. In this case you should save the file with the same
name, but adding an "r" as a suffix to the file name: is a good rule to don't never change the name of a picture, especially if it's part of a series.</p>
