Just need a batch script that will move one folder and all its contents into another folder.
Essentially this
C:\Folder1 to C:\Folder2\Folder 1
You can use windows native command:
MOVE [/Y | /-Y] [drive:][path]dirname1 dirname2
You can use move /?
call for more details.
So, in you case , the command would be:
move C:\Folder1 C:\Folder2\
If Folder2 doesn't exist, Folder1 will be renamed Folder2.
