Clean Your Disk Drive of Unnecessary Files and Your Computer’s Performance Will Improve

When it comes to maintaining your computer, you’ve probably heard it all before. “Run Defrag!” “Scan Your Disk for Errors!” Although these two activities are important, there’s  more you can do to extend the life of your computer beyond today’s predicted two-year span. In fact, by following the simple advice below, you can enjoy the use of your computer to up to five years or more – reserving expenses to simple software upgrades rather then complete and costly hardware upgrades.

One of the easiest and least expensive things you can do to extend the life of your computer is to get rid of unnecessary programs, folders, and files. A disk drive that’s clogged with unnecessary and unused files is disk drive that works harder than it has to. Although Window’s defrag system can ease some of the stress that these files place onto the drive, it doesn’t do much to get rid of the problem in the first place. This is because the defrag program simply organizes the files in a system that makes it easier for the computer to access. (Thus cutting down on the work required to find and load them). But this method merely “relieves” the symptoms that these files induce  – it doesn’t attack the cause. These files need to be deleted – not “organized!”

Of course, deleting files can be a scary adventure to most users. Most computer users don’t know which files are safe to delete and which aren’t.

The worst thing anyone could do is snoop around crucial Window directories and haphazardly delete files that don’t look familiar. Doing so could render important programs inoperable, corrupt the Windows operating system, and possibly prevent the computer from even starting. That’s why using special deletion software is so important. Deletion programs will analyze a computer’s operating system and installed programs to determine which files are crucial to computer function versus which files are safe to delete.

You already have such a program on your computer and it’s Windows’ Add/Remove Programs (available from the Control Panel). This software will assist you with deleting programs that you not only no longer want, but additional files that these program use as well (dynamic link libraries, database files, registry references, shortcut icons, etc.).

But sometimes Windows’ Add/Remove Programs isn’t enough. Although this software does a pretty good job of removing unwanted programs, it can leave some files behind even after a complete uninstall – files which become orphan files. And it’s these orphan files that can really clutter up a hard drive and shorten the life of an otherwise, young and robust PC.

Orphans are usually files that contain temporary data created by a program, files created by the user, partial files left over from a computer crash, or any other kind of miscellaneous files created for almost any other reason. The problem is that an uninstall program doesn’t delete the orphan files it leaves behind because they were never part of the program when it was first installed. An uninstall program can remove only the files it placed onto a hard drive during its install routine.

So while Windows’ Add/Remove Programs can remove an entire program, you’ll need to get rid of those pesky little things with a more advance file cleaner like CleanSweep for example. CleanSweep is a unique program that will specifically seek out files that are no longer associated with a program, and then ask if you want to delete them.

The only time that you wouldn’t want to delete an orphan file is if the file were an actual document that you created before deleting a program. If you were to say, uninstall Microsoft Word, all the documents that you created with Word would then turn into orphan files. Or if you were to uninstall a graphics-editing program, all the pictures you made with the program would become orphan files.

The smart thing to do when you don’t want to lose the data that you created with an unwanted program is to:

1.    Save or convert your documents to a format that will work with different program first (that is, a program that you intend to keep)

2.    Archive them onto a floppy disk, flash drive, or CD-ROM

3.    Proceed with a program like CleanSweep. 

Using CleanSweep or any other similar type of utility could delete anywhere from less than a megabyte of hard drive space to over five megabytes and up. That may seem like a small amount of “clog material” to you, but to your computer, it’s a lot less to process!

Working With Computers

In Today’s Society, There’s No Escape

Well, we’ve been warned that this time would come – probably from the earlier eighties on. Yes, computers have finally taken over and if you doubt it, we’re here to convince you - but not because we want to or because we can. We want to convince you that if you don’t take the necessary steps to control that reign, you’re going to be left behind further than you could have ever imagined.

Computers are everywhere. Take a moment to try and think of a place a business where you didn’t see a computer in use. From the small local corner store to the largest hospital, computers are in every gas station, grocery store, bank, restaurant, beauty shop, and doctor’s office around. From a consumer’s point of view – you may not think that’s much to worry about. But along with computers, we’ve also been infiltrated with a little thing called “self-service.” Today, there are more self-serviced resources than ever and in an effort to synchronize them with headquarter databases, they’re provided via your inescapable computer.

viced through the desktop-clad ATM machine. Gas stations are self-serviced through a menu-clad touch screen kiosk. Most cash registers are Windows XP or Vista machines that send purchase details back to headquarters via the Internet (or a small Intranet). Having your weight, blood pressure, and heart rate measured and recorded is now a digitized process. Even ordering a pizza is now a simple matter of dialing from a wireless cell phone and making a few selections from series of pre-programmed menus!

The important thing to realize here is that this phenomenon isn’t a new convenience – it’s a new requirement. And if you haven't jumped onto the binary wagon, you’re going to face a few problems. For just as this new lifestyle was once predicted, we’re going to predict that “the old ways” will slowly disappear.

We’re going to predict that all paper-based transactions (checks, money orders, etc.) and documentation (think of the old filing cabinet system) will disappear. We’re going to predict that chips will replace everything that was once transported from one location to another through the trusty post office. And we’re going to predict that homes will become less cluttered with stacks of paper and that our natural resources will flourish as a result of it.

This all sounds fine and dandy of course, but if you’re not computer savvy, you’re going to feel a little lost once the choice has past and the revolution is 100% complete. Fortunately, computer systems are designed in a way that even a child can manipulate them. In fact, if you can remember that most systems are designed along the line of menus and the selections of a few options on these menus, you’ll do just fine no matter how many buttons there are to push.

Computers Desktop

 

For example, when you’re faced with an electronic system, look for a main menu. Most main menus display themselves as soon as a device is turned on, so chances are that if you’re standing before a device that shows a bunch of choices to do something, you’re looking at a main menu. The buttons on these main menus of course take you to additional menus, which in turn give you even more choices to make. And all of those choices will eventually bring you to the service that you need. One very important choice you’ll want to keep your eye on is the option to return to the main menu. This way, you can return to the beginning of a system and start over in case you get lost among the way.

Another important choice that you want to keep your eye on is the choice to get help! This option may not be available on every device that you encounter, but when it is available, be sure to use it.

There’s just no way around it. Computers and computerized systems are here to stay. There’s no need to fear them – but you surely can’t avoid them. Just remember the menu system and you’ll soon discover that you can approach and use these things as if you designed them yourself.

Viruses in Computers

What They Are And One Reason Why People Make Them

Over recent years, computers have become synonymous with viruses and viruses don’t show any signs of disappearing any time soon. In recent news, LiveScience.com reported that “Before the month is even done, April has set a record for virus e-mails.”[1] In the past, we would be comfortable in telling new computer users not to worry about viruses and that catching a computer virus is rare. Today, that would be some of the worst advice we could give anyone. As reported in countless news reports, computer viruses are rampant and they’re extremely worrisome. This article will describe what viruses are and then point you in the direction of some rather unique protection and prevention.

In short, a computer virus is a software program designed to destroy or steal data. It attacks computers via distribution – often unknowingly – through email attachments, software downloads, and even some types of advanced web scripting. Viruses that destroy data are known as Trojan horses, viruses that explode their attacks are called bombs, and viruses that duplicate themselves are called worms. Some viruses are a combination of each, however they can be further identified according to where they’re located on a computer.

A virus originating from the boot sector of a computer is a boot-sector virus and this nasty devil does its dirty work the moment a computer is turned on. A virus that attaches itself to (infects) other programs is a file virus and activates the moment that an infected program starts. File viruses may also be referred to as parasitic viruses, however should a virus work from both the boot-sector and from an infected program, the virus is then known as a multipartite virus.

Here are some examples. Banking is self-ser

Why viruses exist remains a mystery, however we had privy access to the mind behind a virus programmer who explained his motivation behind his destructive inclinations. Apparently, this person had a deep grudge against a popular online service which shall remain unnamed. In this hacker’s mind, the online service failed to do a quality job in protecting children from online smut and as retaliation, he created and distributed a virus to as many file libraries of this service as he could. His intentions were to disable the computers of the online service’s users so much that they wouldn’t be able to connect for days. In his mind, the loss of connection meant loss of revenue for the online service.

Although the malicious code that this person generated may have worked for a small percentage of users, sufficed to say, the online service continued on and still exists today. Despite his motivation or intention, his efforts were null.

We wouldn’t be surprised to learn if other motivations behind spreading viruses were similar to this person’s, but that doesn’t justify the damage that viruses do. Innocent people become pawns for the evil plans of others who’ve convinced themselves they’re doing the “right” thing.

To protect a computer from getting a virus, or clean a virus from a computer system once infected requires the use of an antivirus utility. But may be something else we can do. Perhaps we could make an effort to educate the people who want put viruses into the public about ways to display dissatisfaction with a service or product that don’t involve harming innocent parties. In doing so, we just might reduce the number of virus news stories and protect our own investments at the same time.

File of Computers What’s That File?

An Introduction to File Extensions

In an effort to be “user-friendly,” Windows (and perhaps some other operating systems) hides the most important part of a file name from new computer users: the extension. Okay – we’re assuming that the reasoning behind hiding extensions is a “user-friendly” one because we just can’t come up with any other reason for hiding them. No harm could ever come from seeing an extension, but plenty could be learned from it. Fortunately you have this article to guide you through some of the most common extensions that you’ll run into.

But before you can see file extensions, you need to turn them on. From Windows Explorer, click on the “Tools” menu, and select “File Options.” Click the “View” tab and then uncheck the box next to “Hide file extensions for known file types.” Click “OK” and you’ll notice that the files in Windows Explorer show a dot and group of three letters after their names. That dot and group of three letters is known as an “extension,” and the extension explains what kind of file it is.

A file could be a plain text file, an image, a sound, a video, or program. But without seeing the extension, you wouldn’t know it unless you double-clicked on it. The following list defines some of the most common extensions that you’ll find on your computer.

• .au – This extension indicates a sound file. Most sound players will load up and play this kind of file.
• .art - This extension indicates an image file that was compressed with AOL (America Online) technology. Both Internet Explorer and the AOL service software can display this kind of file, however if you don’t have AOL installed on your system, Internet Explorer will display it.
• .avi - This extension indicates a video file playable by most multimedia viewers including Microsoft’s Media Player.
• .bmp - This extension indicates another image file that might have originated from Windows Paint program.
• .dll - This extension indicates a Dynamic Link Library which may contain additional programming code for software. Many different programs often share Dynamic Link Libraries and you’ll find a bunch of them in the Windows/System directory (but don’t ever delete them)!
• .exe - This extension indicates a program or an application like Microsoft Word, Internet Explorer, or Outlook Express. Use extreme caution when downloading .exe files from the Internet since malicious programmers like to hide viruses in these types of files.
• .gif - This extension indicates another image file and it stands for “Graphics Interchange Format.” .Gif files are often smaller than .bmp files (described earlier) and they’re commonly found on Internet web pages.
• .jpg - This extension indicates yet another image file and it stands for “Joint Photographers Experts Group.“ Like the .gif file, it’s commonly found on Internet web pages, however it’s much smaller than both the .gif image and the .bmp image.
• .mid - This extension indicates a sound file created with a Musical Instrument Digital Interface. Windows Media Player will open and run these files, however they don’t sound like normal .wav or .mp3 files (described later). .Mid files are designed to product synthetic sounds using a computer’s sound card.
• .mp3 - This extension indicates a sound file that authentically reproduces voice and/or music. Windows Media Player will open and run this kind of file.
• .scr  - This extension indicates a screen saver file.
• .sit - This extension indicates a Macintosh archive StuffIt file. They will not open on a Windows system without a special utility.
• .ttf  - This extension indicates a font especially designed for use on a Windows system. It stands for “True Type Font.
• .txt - This extension indicates a plain text file that can be opened with Notepad.
• .wav  - This extension indicates a sound file that like the .mp3 file, can be opened with Windows Media Player or Windows Sound Recorder. .Wav files are much larger than .mp3 files.
• .zip - This extension indicates a Windows archive WinZip file. They will not open on a Macintosh system without a special utility.
