Powershell scripting: Moving files from main folder to specific subfolders


I am new to powershell and scripting and as my first task need to accomplish the following:

1. I have a main folder c:\test\

2. The folder has a list of configuration files for multiple applications.
•      c:\test\con_companyname_appname1_config1.txt
•      c:\test\con_companyname_appname1_config2.txt
•      c:\test\con_companyname_appname2_config1.txt
•      c:\test\con_companyname_appname2_config2.txt
•      c:\test\con_companyname_appname3_config1.txt
•      c:\test\con_companyname_appname3_config2.txt
•      etc

5.  There are over 40-50 such appnames with corresponding config files.

4.  What the script needs to do is :

a. Create subfolders for each appname: example
•      c:\test\appname1
•      c:\test\appname2
•      c:\test\appname3
•      etc
              b: Then move the corresponding config files for each  ‘appname’ to the respective appnames subfolder.

I started learning PowerShell recently and what I have so far is:

$fileNames = Get-ChildItem | where {!$_.PsIsContainer} | Select-Object Name

ForEach($fileName in $fileNames) {
$fileName = [string]$fileName
$elements = $fileName.Split("_")
$appNames = $elements[2]
mkdir $appNames

This successfully creates the subfolders by appname under c:\test.
•      c:\test\appname1
•      c:\test\appname2
•      c:\test\appname3
•      etc

But I am not sure on how to move the corresponding configuration files for each appname to the respective subfolders.

5. So the final results should look like this:

•      c:\test\appname1
•      c:\test\appname2
•      c:\test\appname3

I would appreciate your help tremendously with helping me complete this script.

Here is a function that will move the files.  I have used the -Force switch on the Move-Item to force overwriting any existing files that may be read only.  If you want to prevent overwriting files it would be necessary to remove the -Force switch and add a test before the move:

function Move-ConfigFiles
    if (Test-Path $BaseFolder)
        $filesToProcess = Get-ChildItem $BaseFolder |  Where-Object {!$_.PsIsContainer} | Select-Object Name
        foreach ($fileName in $filesToProcess)
            [string]$fileName = $fileName.Name
            $appName = ($fileName).Split("_")[2]
            $appFolder = Join-Path -path $BaseFolder -ChildPath $appName
            if (!(Test-Path $appFolder))
                New-Item -path $BaseFolder -name $appName -type directory | Out-Null
            Move-Item -Path (Join-Path -Path $BaseFolder -ChildPath $fileName) -Destination $appFolder -Force
        Write-Warning "Unable to locate folder $BaseFolder"

Move-ConfigFiles C:\test
