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.
