You can do a lot of things faster using dos commands in Windows. For example, if you want to move all files from a directory to another with subfolders, you can use the following code:

robocopy C:\BaseDirectory D:\TargetDirectory *.* /E /XD D:\TargetDirectory /move

This code uses robocopy which is included on windows7 and over systems by default.
If you don’t have robocopy on your system, you can try using xcopy command too.
