How to copy a file to another folder while a process is using it

Question

How do I copy any file that is being used to another process to a specified folder, without affecting / corrupting what that process is doing?

Context: I'm making a program that will copy a project folder each X minutes to 2 cloud servers and 1 hard-drive, while that project is still open.

As mentioned in the post below:

The important part is the FileShare.ReadWrite when opening the FileStream

.

In short, make sure that you specify the correct access parameters while opening the file.
