Create folder with current date as name in powershell

$folderName = (Get-Date).tostring("dd-MM-yyyy-hh-mm-ss") 
New-Item -ItemType Directory -Path "E:\parent" -Name $FolderName

It is creating folder with name 11-06-2020-07-29-41 under E:\parent

Yes.

New-Item -ItemType Directory -Path ".\$((Get-Date).ToShortDateString())"

or as alroc suggested in order to get the same formatting no matter the culture.

New-Item -ItemType Directory -Path ".\$((Get-Date).ToString('yyyy-MM-dd'))"

Don't use ToShortDateString() as @notjustme wrote; its formatting is dependent upon locale and your date format settings in the Regional & Language control panel. For example, on my PC right now, that would produce the following directory name:

C:\Users\me\09\18\2014

Explicitly set the format of the date string instead.

New-Item -ItemType Directory -Path ".\$((Get-Date).ToString('yyyy-MM-dd'))"
