Backup gives me one folder containing every thing. If I used backup, I will not able to access any file or folder on HD_B (which is I do not want this). I am looking access folders and files on HD_A as well on HD_B.
One week later I added another 10 folders and 13 files to HD_A.
How can I add these new folders and files to HD_B as well? (it is obvious I can added them manually, but it is not always easy to remember which folders or files are news ).
Therefore I am looking for a program to do that (not manually) for me, comparing between two HDs (my case HD_A and HD_B) and add the new folders and files to the one that it does not have (my case HD_B) them (only new folders and files)?
Note: Differential Backup is not the one I am looking for.
