# Path to the current directory
$baseFolder = Get-Location

# Path to the JPG folder
$jpgFolder = Join-Path $baseFolder "JPG"

# Path to the RAW folder

# Iterate through all .jpg files in the JPG folder
foreach ($jpgFile in Get-ChildItem "$jpgFolder\*.jpg") {
    # Extract the file name without extension

    # Check if a .dng file with the same name (excluding the file path) exists in the RAW folder
    $rawDngFile = Get-ChildItem "$rawFolder\*\*.dng" | Where-Object { $_.BaseName -eq $jpgFileName }

    if ($rawDngFile) {

        $rawSubFolder = $rawDngFile.Directory.FullName.Replace($rawFolder, "")
        
        # Create paths for the destination folders

Example input

Base Folder
├── JPG
│   ├── image1.jpg
│   ├── image2.jpg
│   └── image3.jpg
└── RAW
    ├── SubFolder1
    │   └── image1.dng
    └── SubFolder2
        └── image3.dng

Example output

Base Folder
├── JPG
│   ├── SubFolder1
│   │   └── image1.jpg
│   ├── SubFolder2
│   │   └── image3.jpg
│   └── image2.jpg  (remains here as there is no matching .dng file)
└── RAW
    ├── SubFolder1
    │   └── image1.dng
    └── SubFolder2
        └── image3.dng
