You have to feel comfortable using File Explorer.
This is one of the most important features in Windows. When you understand how to use this program, you’ll always be able to find Files on your PC. One of it’s main benefits is to create sub-folders under a main Folder, like Pictures. The new sub-folders can be named anything you want. You’ll then be able to move all the pictures related with the sub-folder topic making them easier to find. It also helps keep your Desktop with fewer icons. Your PC slows down exponentially when you monitor is over half full of icons.
