Meet the command prompt - the MD command

This command has a twin, MKDIR. Their function is to create a new directory (folder). The command creates all the directories that do not exist.

This command can be use to create a directory structure some levels deep. for example

md folder1\folder2\folder3
The above command will create three folders. the folder named folder1 will be created in the current directory. In folder1, there will be another folder named folder2. This folder will also contain the third folder, folder3.

This command has quite some "power". Look at the post on how to create an undeletable folder.
