Version 2025 of Altova DiffDog was announced on October 22, 2024. Learn about all the new features below and update to the latest version.
In addition to comparing files, databases, and directories, DiffDog 2025 can now search through a folder and its subfolders to identify duplicate files, i.e., those with the same filename and contents. Users can see the location of duplicates to make decisions about which file(s) to save.
This functionality makes DiffDog even more useful for maintaining folders and directories that have grown over time, helping to save storage space, eliminate redundant resources, and improve overall data integrity.
Learn about all the additional capabilities you’ll get by upgrading from an older version to DiffDog 2025.
