comp c:\reports \\sales\backup\april 

Answer 2

The easiest way would probably be downloading diff for Windows: http://gnuwin32.sourceforge.net/packages/diffutils.htm
You could also do something like:

dir directory1 > dir1
dir directory2 > dir2
comp dir1 dir2

Also, some versions of Windows comes with windiff, however that is a GUI tool

In Windows 10 you can run diff command in bash by Enabling the Linux Bash Shell
