A file extension is a three- or four-letter code that indicates the file format of a given file. For example, the file extension ".doc" indicates that the file is a Microsoft Word document, while the file extension ".jpg" indicates that the file is a JPEG image.
File extensions are important because they tell your computer which program to use in order to open a given file. For example, if you try to open a ".doc" file in Microsoft Word, the program will know how to open it and display its contents. However, if you try to open a ".doc" file in Microsoft Excel, the program will not be able to open it and will instead display an error message.
There are thousands of different file extensions in use today, and new ones are being created all the time. While most file extensions are associated with a specific program, there are some that can be opened with multiple programs. For example, the ".txt" file extension can be opened with a text editor like Microsoft Word or a word processor like Adobe Acrobat.
If you're not sure which program to use to open a given file, you can usually find out by doing a web search for the file extension. For example, a search for ".doc" will return results for Microsoft Word and other programs that can open ".doc" files.
