• Open the Start menu, click on the Windows icon at the bottom left of the taskbar
• Type cmd in the search bar, righ-click on the cmd icon, and select "Run as administrator"
• Once the command prompt has opened, create a new file with the name "name_of_file.extension" of size "size_in_bytes" at the location "path_of_file" by tipping : 

fsutil file createnew [name_of_file.extension] [size_in_bytes] [path_of_file]
