AllDup is a free utility developed by Michael Thummerer Software Design (MTSD) to identify and manage duplicate files on Windows systems. It helps users scan their hard drives to find duplicate data and free up storage space. The program supports multiple search criteria, enabling examination based on file name, content, size, and other attributes. AllDup also offers tools to delete, move, copy, or rename duplicate files, and includes preview features for images, text, sound, video, and internet files directly within the program.

Streamlined duplicate detection with flexible search options

At its core, AllDup focuses on scanning for duplicate files across a wide range of file types on Windows. Users can customize their search by selecting criteria such as filename, file extension, size, content, similar images, similar music files, and more.

Features such as filtering, archive searching for formats including ZIP, RAR, 7Z and others, and ignoring specific metadata such as ID3 tags, Exif data, and FLAC metadata allow highly accurate and comprehensive scans. Additionally, the interface is designed to clearly display duplicate groups and provides multiple automatic selection commands to simplify cleanup.

Controlled file management enhances safety and organization

Once duplicates are found, AllDup offers several options for handling them. Users can delete duplicates either permanently or by sending them to the Recycle Bin, create hard links or shortcuts, move duplicates to backup folders, or rename them. Moreover, a built-in preview function and a detailed log file help ensure safe file management and reduce the risk of accidental data loss.

Reliable for managing redundant data on Windows

AllDup provides a clear and effective way to manage duplicate files using multiple search criteria and safe file handling options. Its straightforward interface and preview capability enhance user control and minimize risks when organizing files. Overall, it remains a solid choice for free duplicate file management on Windows environments.
