We'll be using the copy command. If you want to get help yourself, you can type copy/?
The copy command consists of two main parts: source and destination, and some optional "switches". The /y switch supresses overwrite confirmation prompts, so we will use it.
Here's an example:
copy "c:\shared files\file.txt" "c:\program files\test" /y
The first part is the source location and file, the second part is the destination folder. You specify a file's complete address, followed by its name and extention, then you specify the destination folder, not a file. The /y switch like I said prevents the computer asking to overwrite files.
It's important that you enclose the addresses in speech marks, or you may get into problems with folder and file names.
Simple write a copy command for each file you need. There are a few tricks when dealing with large ammounts of files. For example,
copy "c:\shared files\*.*" "c:\program files\test" /y
Will copy the entire contents. I hope this helps! Test it works first.
