The emoji are circulating more and more lately. You can use them in almost any application on your computer.
The news is that you can also use them as file and folder names in Windows 10.
To "write" one emoji in a file or folder name, just press the keyboard shortcut while renaming the file or folder and a selection window will open.
All this is possible due to Unicode. Unicode contains "characters for all the writing systems in the world, modern and ancient," according to The Unicode Consortium. Includes emoji and many other symbols.
You will notice that, the emoji in file and folder names are not displayed in color as they are elsewhere in Windows.
