How to create batch file for copy command?

Question

I'd like to combine two files together using the copy command as follows. This is simple enough using

copy /b base.txt + file1.txt combined_file1.txt

however the first part of the file (base.txt) will remain constant and the second half will be from a folder full of different file (such as file1.txt, file2.txt, file3.txt etc)

The output file should be the variable filename with combined_ added at the front.

I'd like a batch file that I can place inside the directory of files and have it automatically add base.txt to the front of all the other variable files.

Here is a powershell script that will do it. Just adjust the base path and the combined folder and the files folder.

$baseFilename = "c:\temp\base.txt"
$addonFolderLocation = "c:\temp\files"
$combinedFolderLocation = "c:\temp\combined\"

#Get all files in addon folder location
$addonFilenames = Get-ChildItem $addonFolderLocation

foreach ($addonFilename in $addonFilenames)
{
    cat $baseFilename, $addonFilename.fullname | sc "$combinedFolderLocation combined_ $addonFilename"
}

edit: added combined_ before filename in combined output
