Find all you need to know about the most common types of files on the internet. Our free Windows tutorials demystify zip, pdf and other types of files
Common types of files in Windows and on the internet When you are working and communicating with friends, family and colleagues you are likely to come across several types of file. Windows can handle many types of files without any additional software and almost all others with additional software. The table below shows you some of the most common types of file and what to do with them:-
* Microsoft word documents can usually be opened with Wordpad, the free word processor built into Windows. However certain Microsoft word documents which use advanced features may not open correctly with Wordpad. As you can see, windows is well equipped to deal with most common types of files. These tutorials will focus on some of the more unusual types of files and how to work with them. Pitfall – Hidden file extensions! One of my least favourite features of Windows is its unhelpful “Hide file extensions” option. A file extension is the three or more letters following the dot on the end of a file name. For example, the file extension of “myfiles.zip” is “.zip”. We covered the “hide file extension of known file types” option in other free Windows tutorials, specifically
Windows XP basics tutorial 6.
Windows Vista users may wish to watch this video too, since understanding the concept of “hidden file extensions” is important. Basically, Windows has the option of hiding the file extension part of a file name. For example, a zip file on your computer may be named “myfiles.zip”. If you have the “ Hide file extensions” option turned on, Windows explorer will show this file as “myfiles”. We are not sure exactly why the designers of Windows made it this way, our best guess was it was an attempt to make things appear less complicated for beginners. 
Above – Windows shows us a file called myfiles.zip, below – exactly the same file and folder but with the “hide file extensions of known file types” option turned on. These files are 100% identical, don't get caught out if you use this option! 
Look at the picture below, with the “hide file extensions” option turned on, it looks as though we can have files with the same name in the same folder! Look closely though and you can see the icons are different. The actual names of these files are myfiles.zip, myfiles.txt and myfiles.bmp, but again Windows is hiding those file extensions from us! 
Now you understand this somewhat confusing state of affairs, you have mastered one of the most common pitfalls when working with files in Windows. This one still catches us out from time to time, so beware! What are Zip files? When transporting a large number of files across the internet, by e-mail the web or any other means, it is not usually convenient to send them one by one. More experienced computer users usually prefer to use Zip files. A Zip file acts like a container, or perhaps a suitcase, letting you put lots of smaller files inside it. Furthermore, Zip files use a special software technique called “compression” which shrinks the size of the files you store to minimise the time it takes to transmit them across the internet. Unlike your holiday suitcase though, squashing more things inside a zip file won't ever cause damage to them. Windows XP and Windows Vista can both open Zip files automatically, just double click on a Zip file to inspect its contents. You may have already been working with Zip files without even knowing it, since clicking on a Zip file simply displays its contents in a Windows Explorer window. Wouldn't it be great to create our own Zip files, to send files and photographs to our friends across the internet? With 7-Zip you can do all that and more, and for free! Check out our free Windows tutorials on 7-Zip:- PC acrobatics?! – What are pdf/Acrobat files? Nothing to do with acrobatics, Adobe Acrobat/pdf files are very common on the internet and in business. In the days before fast, powerful multimedia computers were commonplace, chances are you would buy a computer program from a store and receive a printed instruction manual. Nowadays more and more companies are saving money by including manuals in pdf format. Pdf files are also used for forms and receipts and sometimes also letters and business correspondence. Unlike web pages or word processor documents, pdf files are designed to look identical on any machine that can open them and in the case of instruction manuals or other documents, identical to the paper hard-copy they are based on. While Windows cannot open pdf files without extra software, the required software is free to download and easy to install. Visit this page to download Acrobat Reader and then install it to start viewing pdf documents on your PC.
