powershell - Create directory if it does not exist

Question

I am writing a PowerShell script to create several directories if they do not exist.

The filesystem looks similar to this

D:
D:TopDirecSubDirecProject1Revision1Reports
D:TopDirecSubDirecProject2Revision1
D:TopDirecSubDirecProject3Revision1

• Each project folder has multiple revisions.
• Each revision folder needs a Reports folder.
• Some of the "revisions" folders already contain a Reports folder; however, most do not.

I need to write a script that runs daily to create these folders for each directory.

I am able to write the script to create a folder, but creating several folders is problematic.

Answer 1

Try the -Force parameter:

New-Item -ItemType Directory -Force -Path C:PathThatMayOrMayNotExist

You can use Test-Path -PathType Container to check first.

See the New-Item MSDN help article for more details.
