? ?There are
literally millions and millions of files available all over the Internet. With a
simple search command, you can find fonts, programs, games, graphics, sounds,
movies, stationery, and just about anything else that you can imagine. In order
to get these products and files, you must learn how to download. Here are some
of the things that are recommended. Make sure you have an anti-virus program
installed, operational and with up-to-date definitions. This is critical as you
may run across a virus and if so, you could put your entire computer at risk.
Anti-virus software is an inexpensive insurance. ? ?If you are
going to install a program, be sure that you’ve updated your emergency disk and
have a recent backup. This is very important for downloads that change system
information. ? ?Store your downloads in a special directory. Create
a directory called "Distributions," and inside that directory put
subdirectories—one subdirectory for each product. In those subdirectories, save
the setup files, documentation and anything else that you need to install the
program. ? ?Store your downloaded treasures on a drive other than
the C drive. This is to keep your C drive for system files and applications, and
your other drives for data. ? ?Find the files to download. There
are so many sites with files to download that it would be impossible to list
them all in one place. There are literally thousands of sites with just graphics
and clip are files alone, much less programs, games and everything
else. ? ?Some good places to start looking include: ?
?Softseek. com—lots of good shareware and freeware products ?
?download, com—more programs to download ? ?Save the
downloaded file in your download directory. Decompress the downloaded file. A
lot of downloads need to be decompressed. The ". ZIP" file type means the file
is compressed and must be decompressed before it can be used. You can do this
with any number of utilities, including Conversion Plus and Winzip. ?
?Files ending with an ".EXE" must be executed. These files will typically
begin a dialog for installation once you double-click on the file. Install or
use the downloaded files. If you’ve downloaded a program, then install it. For
graphics and sounds and such, use as appropriate. ? ?Clean up. If
you are limited on disk space, you should delete the . ZIP or . EXE file that
you downloaded once you’ve installed the application. You should also clean up
any other miscellaneous files that are left over from the download process.
Delete the files in TEMP directory after doing any kind of installation.
