File Extension Lab
As technology evolves and more software applications are developed, we need to employ a system that makes it easier for us to tell what kind of file we are using or receiving. A file extension does just that!
The file extension gives your operating system the information it needs to choose the correct software program to open the file. Indicating the file format of the information contained within a file, the file extension often gives hints about what kind of information the file contains. Simple and common file extensions include .txt for plain text, .exe for executables, and .mus for music. While you may be familiar with the more common file extensions, thanks to the proliferation of new software programs and operating systems there are many more that may be foreign to you.
We have made discovering file extension types easy and painless! Simply scroll through the list of file extensions below to discover the types of file format that is indicated by the extension.
