Export text based file list for the difference between 2 directories (Windows version)

The following is a tutorial for exporting a text-based file list showing the difference between 2 directories (e.g. D:\DirA, D:\DirB):

Step 1: Create a text-based file list for both directories

> cd D:\DirA
> dir /s /b /a:-d > file-list-dir-a.txt
> cd D:\DirB
> dir /s /b /a:-d > file-list-dir-b.txt

Step 2: Use WinMerge to get the difference between the 2 file lists:

Note: To display difference only, you need to set "View > Diff Context > 0 Lines".

Step 3: Copy the difference from WinMerge and create a text file to store it.
