Can I use C#/Unity like a batch file (move/find files on the hard drive)?

Just as simple as the title - Can I use C# to find/move/copy or even download files from the internet and place them into a folder? I’m 100% aware I can use a batch file, but I was wondering if it were possible. If you know anything about this, can you please give me examples and/or link(s) to places I can become informed? Thank you.

Not sure what you mean by “like a batch file”, but yes you can move/copy files using the methods in System.IO.
