Move and Manipulate files across directories - Powershell - windows

Question

I am trying to move a list of files from one directory to another. The catch is, When the items are moved to the new directory, I want to automatically organize them.
Ex..
I have a folder of thousands of filenames.
All filenames are relative to a user's userID. Some users have multiple files in this folder, so it appends a number onto the end of the name. I.E. susy.txt, susy1.txt, susy2.txt, carl.txt, carl1.txt, etc...
What I am trying to do is create a specific folder (in the new directory) for each user that has multiple files, and move all associated files into that folder. So I notice there are multiple susy documents. So I want to create a folder named Susy and place susy.txt, susy1.txt, and susy2.txt into it... And so on for all files.
Is it even possible to do this as a batch file, if so can someone point me in the correct direction on doing this? I have a small amount of knowledge in writing batch scripts, and would like to take this as an opportunity to learn more.
This is very similar to a question I have asked earlier. File and Folder Manipulation in Powershell. I am very thankful for the responses I received, they helped me greatly. The answer from Adi Inbar was exactly what I needed, at the time. However, I was forced to make a modification, which I have tried myself.
Adi Inbar's Answer
Get-ChildItem | ?{$_.Name -match '(\D+)\d*\.txt'} | %{
md $matches[1] -ea SilentlyContinue
Move-Item $_ $matches[1]
}
Short sweet and too the point, exactly what I needed. However it only works for for files that are going to be organized but stay in the same parent folder.
This is what I have attempted:
Get-ChildItem –path "P:\My Documents\Org Test\Test1" | Where{$_.Name -match '(\D+)\d*\.txt'} | Foreach{
md P:\'My Documents'\'Org Test'\Test2\$matches[1] -ea SilentlyContinue
Move-Item $_ P:\'My Documents'\'Org Test'\Test2\$matches[1]
}
To my knowledge and basic understanding this should work... But I am getting an error saying Move-Item : Cannot create a file when that file already exists.
At P:\My Documents\Org Test\Test.ps1:3 char:3
+ Move-Item -Path P:\'My Documents'\'Org Test'\Test1\$_ -destination P:\'M ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : WriteError: (P:\My Documents...t1\Johnny123.txt:FileInfo) [Move-Item], I
+ FullyQualifiedErrorId : MoveFileInfoItemIOError,Microsoft.PowerShell.Commands.MoveItemCommand
I am sure that it is on the tip of my tongue, but I cannot get it. I have very basic powershell scripting experience and just need a quick fix.
EDIT:
I have been able to "resolve" my issue by using this script:
Get-ChildItem –path P:\'My Documents'\'PST Org Script'\Test1 | Foreach-Object{
move-item -Path $_.fullname -Destination "P:\My Documents\PST Org Script\Test2" -ea SilentlyContinue }
cd P:\'My Documents'\'PST Org Script'\Test2
Get-ChildItem | ?{$_.Name -match '(\D+)\d*\.txt'} | %{
md $matches[1] -ea SilentlyContinue
Move-Item $_ $matches[1]
}
I am curious. I feel like this can be done in the 3 lines of code I have above. This seems like a little redundant. But what do I know.
Thanks

Answer 1

Try this:
$srcPath = 'P:\My Documents\PST Org Script\Test1'
$dstPath = 'P:\My Documents\PST Org Script\Test2'
Get-ChildItem $srcPath | Where {$_.Name -match '(\D+)\d*\.txt'} |
Foreach {$targetDir = Join-Path $dstPath $matches[1]
md $targetDir -ea 0
Move-Item $_ $targetDir -WhatIf}

Answer 2

I have been able to resolve my issue using this:
Get-ChildItem –path P:\'My Documents'\'PST Org Script'\Test1 | Foreach-Object{
move-item -Path $_.fullname -Destination "P:\My Documents\PST Org Script\Test2" -ea SilentlyContinue }
cd P:\'My Documents'\'PST Org Script'\Test2
Get-ChildItem | ?{$_.Name -match '(\D+)\d*\.txt'} | %{
md $matches[1] -ea SilentlyContinue
Move-Item $_ $matches[1]
}
However I feel, there is a shorter, simpler way of doing this via some variation of the method I entered earlier in my original question.
