FILE TYPES in Windows Explorer  '98

Lesson 8

Normally, I would not recommend having a beginner do anything with the settings of your CPU. However, you need to know how file types influence the operation.   A File Extension is the ending of a file name like ".doc". This name extension designates the type of file it is.  Windows will then analyze the file extension and go to the register to find what default program this file will run in.  You can open a file by double clicking the selected file in Windows Explorer or in the "Find" mode as well as right click mouse to get to menu then select "Open". Windows will then open the program and then display your file that you clicked to open. It happens so quick that you think the file is the program. It's not!  When you install a program it tries to automatically makes their file extensions the default. To find out which program opens a file type, go to "Start" button, Select "Settings", Select "Folder Options"
When you click on "Folder Options" (above) this window or image will appear.
Notice there are 3 tabs across the top of the form. We are only concerned with tab 3 "File Types" 
Note that Microsoft Word Document is highlighted. At the bottom it indicates the file extension associated with Word documents is "DOC". The application it will run in is "Winword" which is the name of MS Word application.  Any file in Windows with the extension ".doc" will open Winword first and then the file if you use a shortcut to open or double click the file while in "Windows Explorer" or "Find".  You can open this file with other compatible programs but you will need to open the application first and select open and then find the file you want to open while in that application.
   This default setting is established when you install an application. If you want to change the default setting to open a particular application, you change it here with the "Edit" button. Beginners should have an experience person edit the settings or you may get unexpected results.
   Scroll bar will allow you to view default setting of all your applications on your CPU and their associated extensions.
The understanding of file types is necessary to understand how you can convert or transfer data from one program to another that isn't normally compatible by using a computer for speed and efficiency that eliminates manual entry. In Windows 95: Open "Windows Explorer", select "View" menu, select "Options", select "File Types". Similar to above.
We have seen a basic use of the Find utility for Windows Explorer Let's continue with File Types from another perspective.
