Hi!

I want to make a backup program which loops through all the directories and files on a drive of my computer and checks if the current directory or file exists on another specified drive. If not, it creates the directory or copies the missing files. If a newer version of a file exists it would be updated.
I'm not asking you for a fully coded solution, however I would greatly appreciate if someone could point me in the right direction.
Thanks in advance,
Nina.
