If you dual-boot and want to have super-easy access to your "big five" directories (Videos, Pictures, Documents, Music and Downloads) then you can use ln to symbolically link the directories from your Microsoft user account into your Linux user account. Ideally you would mount your Windows partition, then sign out, sign in via TTY (Ctrl + Alt + Fx; Fx being F1-F6, and may require holding down the Fn key depending on your keyboard and / or BIOS settings) and using rm -rf to delete your default directories, to then replace with links.
After you can Ctrl + Alt + F7 to return at your X session, sign in and enjoy not juggling two separate sets of directories for your common files. (They even preserve their default icons!)
Now, should you reinstall and keep your home directory, you'll probably need to use XDG utils to re-assign your common directories so their icons are restored, but eventually you will persevere.
