@GitHub Copilot - Welcome @BanterBoy, I’m your Copilot and I’m here to help you get things done faster. I can identify issues, explain and even improve code.

You can ask generic questions, but what I’m really good at is helping you with your code. For example:

Generate unit tests for my code Explain the selected code Propose a fix for the bugs in my code If you want to learn more about my capabilities and limitations, check out the Copilot documentation.

I’m powered by AI, so surprises and mistakes are possible. Make sure to verify any generated code or suggestions, and share feedback so that we can learn and improve.

@BanterBoy: - Explain what the script does and why it is useful.

#File/folder comparison tool to check a source and destination for missing files/folders
#Reports missing source files, ignores extra files on the destination

Find-MissingFiles.ps1 | Out-File MissingSource.txt

$SourcePath = '\\SERVERNAME\TVShows\Filed'

#Equivalent cmd for 'dir /b /s'
$Source = (Get-ChildItem $SourcePath -Recurse).FullName
$Dest = (Get-ChildItem $DestPath -Recurse).FullName

#1/-1 - Different, 0 - Same

#Cleanup to make the paths appear same
#Basically removing the uncommon source and destination paths portion
for ($i = 0; $i -lt $Source.Count; $i++) {
    $Source[$i] = $Source[$i].Replace($SourcePath, "")

for ($i = 0; $i -lt $Dest.Count; $i++) {
    $Dest[$i] = $Dest[$i].Replace($DestPath, "")

#Loop the Source files
foreach ($fileS in $Source) {
    #Counter for match
    $Found = $false

    #Loop destination files to Compare with each source
    foreach ($fileD in $Dest) {
        #Check Exact Match
        if ($fileD.CompareTo($fileS) -eq 0)
        { $Found = $true }

    #Writeout missing files
    if (-not $Found)
    { "$SourcePath$fileS" }
