? ?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.

Before you download anything from the Internet, you should first of all ______.

A:make sure that you have installed anti-virus program B:make sure that you have updated your backup C:create a directory to store your downloads D:make sure that you have cleaned up your disk space
