TreeSize Professionalv7.1The powerful disk space management software

Check for duplicate files using the integrated duplicate file search

If a system is used by multiple or constantly changing users, you'll find that files and sometimes even entire file trees have been duplicated over the years. They use up disk space, so removing duplicates (a process called "Deduplication") is a task that should be performed at regular intervals. But how do you find duplicate files?

The TreeSize duplicate file search enables you to look specifically for redundant files on your hard drives, folders, or network shares. It employs MD5 or SHA256 checksums to compare files and find duplicate content.

In addition, TreeSize enables you to easily deduplicate files (i.e. deletete duplicates or replace them). It offers a variety of options to select specific files for deletion and leave others untouched. Would you like to delete all but the newest file of each duplicates group or files from a certain path? TreeSize helps you to to define a custom search pattern that checks all files that match the given criteria. Once selected, you can easily move, delete, or archive all checked duplicate files, using the option Move Checked Files.

You can run duplicate searches automatically with the comfortable TreeSize task planner in the Professional Edition.

You may also compare files by their size, date, and/or name. This is faster but less accurate, since it does not take a file's content into account.

You want to perform duplicate searches for single user accounts? Try SpaceObServer, the database-based disk space manager.
