Deletes a directory along with all of the files and subdirectories that it contains. Normally, it will ask for confirmation of such a drastic action.
deltree [/y] directory
The /y parameter if present tells the deltree command to carry out without first prompting for confirmation.
The deltree command is not included in recent Microsoft Windows operating systems. Deleting a non-empty directory in those versions of Windows where the command is not included, can be achieved by the use of the rmdir command as in the following example:
rmdir /s directory
