File extensions basically let you know what type of information is contained in
a particular file. For example a note pad file has the .txt extension. This
means it is a text file.
Here are
some other examples of file extensions.
-
.exe (An executable file, usually
the file that starts a program.)
-
.pdf (Portable
Document Format, is a file format created by Adobe Systems. Most office
documents come in .pdf file format.)
-
.zip/.rar (These could be any file
but they have been compressed and packed away to a smaller size. When unpacked
or unzipped it will become what it was originally.)
-
.wav/ .mp3 (Music files)
-
.jpg/.gif/.bmp (Picture file
formats)
You will see most of these file extensions on your computer. To show file extensions:
1. Open any folder on your computer.
2. Choose "Tools" - "Folder Options".
3. Click the "View" tab.
4. Uncheck "Hide extensions for known file types".
5. Click "OK" to close the dialog box.
