Do you know how I can use RoboCopy?
You can get all the command line options and syntax at the command line by typing robocopy /?. The documentation is also online here:
https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/robocopy
But if you're not comfortable at a command line then I recommend using the other program I linked, FastCopy, because it has a point and click interface (it can also be used via the command line) and it preserves Date created by default. Just pick your source and destination and click Execute.
