Compares the subfolder names inside two parent folders. For every subfolder name that exists in BOTH parents, all files inside the subfolder under SOURCE_PARENT are moved into the matching subfolder under DEST_PARENT.

Usage:

  python move_matching_folders.py "C:\path\to\Source" "C:\path\to\Dest"

Optional flags:

1. -dry-run Show what WOULD be moved, without moving anything.
2. -recursive Also move files from sub-subfolders (keeps folder structure).
3. -overwrite Overwrite a file in destination if same filename exists.

(default: skip and keep both — renames with a suffix)

Example:

  python move_matching_folders.py "D:\Old\Clients" "D:\New\Clients" --dry-run
