Here is a complete, master list of all major video formats used across computers, phones, broadcasting, and the web, categorized by their primary use: 1.

When you are handling student records, office documents, or large media files, organizing them correctly ensures you can find any file in less than 5 seconds.

You can see these by opening File Explorer (Windows Key + E) and clicking This PC . Local Disk (C:): This is where your computer's Operating System (Windows) and all your installed software live.
