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

The filesystem looks similar to this

D:\
D:\TopDirec\SubDirec\Project1\Revision1\Reports\
D:\TopDirec\SubDirec\Project2\Revision1\
D:\TopDirec\SubDirec\Project3\Revision1\
  • 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.

Try the -Force parameter:

New-Item -ItemType Directory -Force -Path C:\Path\That\May\Or\May\Not\Exist

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

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