Have you ever wondered what file extensions were and why they can become so annoying when you try to open files? The File Extension Library has all the information you need, from file extension MP4 to file extension dot. The way the library works is once you find the file extension you want to know more about, you can go to its page and learn many things. You will be able to find out what type of a file this extension belongs to, what programs can run these files, and how to fix any errors with the file so you can open it without corruption.
The Extension Library is useful for both the novice and expert techie. So if you want to know more about DWGs and EXEs, check it out.
