+.SYNOPSIS
+    Scans a directory and its subdirectories to find duplicate files based on content.
+
+.DESCRIPTION
+    This script recursively searches through a specified directory, calculates the SHA256 hash
+    for each file, and then groups files by their hash. It reports any groups of files
+    that have identical hashes, as these are content-based duplicates.
+
+.EXAMPLE
+    .\Find-Duplicates.ps1
+    (After setting the $targetDirectory variable inside the script)
+#>
+
+# --- CONFIGURATION ---
+# Set the directory you want to scan for duplicates.
+# IMPORTANT: Replace "C:\Path\To\Your\Directory" with the actual path.
+$targetDirectory = "C:\Path\To\Your\Directory"
+
+# --- SCRIPT ---
+
+# Check if the target directory exists
+if (-not (Test-Path -Path $targetDirectory -PathType Container)) {

+# 2. Calculate the SHA256 hash for each file.
