powershell copy and rename specific folders

Posted on 2009-04-02
Last Modified: 2012-06-27
I am a Powershell newbie and I am trying to make copies of specific folders and rename them to include the date in the same root folder. The are other folders in that folder that contain a previous date.

      1_1_09 Test1
      1_1_09 Test2

I want to achieve this:

      1_1_09 Test1
      1_1_09 Test2
      <current_date> Test1
      <current_date> Test2

How can I accomplish this?

Thank you!

I have found a script that I can modify to do what I need, but I was wondering if there is another solution.

I tweaked my own script a little so it suites your needs. What it does is it looks up all the folder in a specific given directory. It checks if the directory doesn't start with a number. If a result is found it renames the directory.

I assumed that the dateformat was day_month_year. You can edit this by using the "d" for the day, "M" for the month and the "y" for the year.

The script asks for a parameter. Your commandline could look like this:
powershell Myscript.ps1 -folder C:\MyfolderThatHasToBeRenamed

Here is the script

Param($folder = $(Throw "No folder given"))

Function RenameFolder([string]$folder){

	# Generate the lookup array

	$arrNumbers = 1..31

	# Create the dateformat

	$date = Get-Date -format "d_M_yy"


	# Lookup all the folders in the given directory

	$arrFolders = Get-ChildItem $folder | Where {$_.psIsContainer -eq $true} | Sort-Object {$_.FullName} -Descending


	# Loop through the array

	Foreach($item In $arrFolders){

		# Convert the item to a string

		[string]$i = $item

		# Get the first character from teh string

		$sub = $i.Substring(0, 1)


		# If the substring is not in the number array than continue

		If($arrNumbers -notcontains $sub){

			# get the old folder

			$old = $item.FullName

			# create the new folder

			$new = $folder + "\" + $date + " " + $i

			# rename the folder

			Move-Item $old $new





# Test if the given folder exists

If(Test-Path $folder){

	RenameFolders $folder


	Throw "The path to the folder doesn't exist"

Thanks for replying and taking the time to modify your script.
This script will be used to copy VMs and it will be scheduled so I can't have user imput and  I don't need to move the contents, just copy them.  If I'm not mistaking move-item $old $new would move the whole old folder to the new folder.

I have also come up with another  simpler script because I also have other folders that do not start with numbers in the root folder. (I know, I didn't mention that previously)

I will give you points for answering most of the problem and giving me some ideas on how to improve my script.

Thank You!

$date = Get-Date -format "MM_dd_yyyy"

$arrSource = @("test1","test2")

$arrTarget = @("$date copy_of_test1","$date copy_of_test2" )

for ($i=0; $i -le $arrSource.Count-1; $i++)


New-Item $arrTarget[$i] -itemType directory

Copy-Item ("C:\Test\" + $arrSSource[$i] + "\*") $arrTarget[$i]
