As the help file says,

This filter is used to join two files together as columns side by side. If File A represents each file from the Files to Process list, and File B is the file being added side by side, then each line of File B gets added to the right hand end of each line from File A.

Now I happen to come across such a situation:

Each line of File B needs to be added to the LEFT hand end of each line from File A. While the content of File A can be various, the content of File B is constant. Is there any simple way to do this in a batch?

Thanks a lot!

Not easily, other than by swapping file A and B.

For a more general solution, you could use the script filter.
