Python Scripting

Implement a file-classification function that normalizes extensions, applies a category mapping, and uses a fallback category for unknown or missing extensions.

Implement destination-path logic that creates a missing category folder and returns the intended destination for a file.

Connect discovery, classification, and destination logic using explicit function parameters and return values instead of global state.

Control script execution with a main function and an if __name__ == "__main__" guard.

Implement a dry-run mode that displays planned source and destination paths without modifying the file system.

Generate a non-overwriting destination path when a file with the same name already exists.

Move a file to its planned destination with shutil when dry-run mode is disabled.

Implement per-file exception handling that records moved, skipped, and failed results while allowing the organizer to continue processing.

Use argparse to accept a source folder and a dry-run option when launching the script from PowerShell or Command Prompt.

Validate the completed organizer in an isolated test folder using normal files, uppercase extensions, extensionless files, nested folders, and duplicate filenames.
