Simplify File Cleanup with Smarter Deduplication

Altova DiffDog is a robust tool for comparing and synchronizing files, databases, and directories, offering a comprehensive solution for efficient data management. It supports a wide range of file types and complex data structures, ensuring precision in comparison and synchronization processes. DiffDog helps streamline data organization, minimize redundancy, and maintain clean, reliable data environments, making it an invaluable asset for managing expanding directories and ensuring data integrity.

The DiffDog 2025 Release 2 update adds deeper control for handling duplicate files across folders and subfolders. Users can now choose to automatically delete all files in a selected folder if identical copies exist elsewhere, retain only the files in a chosen folder by removing their duplicates, or remove all duplicates of a specific file to preserve a single copy. These new actions streamline cleanup tasks, reduce storage waste, and give users confidence when managing redundant files in complex directory structures.
