If multiple or constantly changing users store data on a system, 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 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 for redundant files on your drives, folders, or network shares. It employs MD5 or SHA256 checksums to safely identify files with identical content. You may also search for duplicate files using a combination of file name, file date and size, which is much faster.
In addition, TreeSize enables you to easily delete, archive, or deduplicate the found files. It offers a variety of options to select specific files for deletion or deduplication and leave others untouched. Would you e.g. 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 pattern that check-marks all files matching the given criteria. Once check-marked, you can easily move, delete, or archive all duplicate files, using the option Move Items.
You can run duplicate searches automatically with the comfortable TreeSize task planner in the Professional Edition, and let you email the results.
You want to perform a duplicate search on a regular base or you have very large file systems? Then try SpaceObServer, the database-based disk space manager, which is able to collect MD5 checksums and file metadata using a background agent and stores it in a database, from where it can be retrieved in seconds. Besides identical files it can also find similar folder structures.
