Fusion

Smart: When fusioning duplicate files, only one copy is kept physically on the drive. All other locations only point to this physical file.

100% secure

Don’t worry, FileFusion is 100% secure. Users don’t notice the fusion and can use their data as usual. Even if you have uninstalled the program the links stay active.

For all systems

This tool has been developed to work perfectly with all NTFS-based hard drives and all Windows versions starting with Windows 7.

Detailed reports

After fusioning all duplicate files, the user receives a detailed report about the amount of freed storage, the number of all fusioned, duplicate files and more.

Innovative Technology

Over time, duplicate files can accumulate on your computer or other storage devices, wasting valuable disk space. FileFusion duplicate file finder software helps identify and remove these duplicates, freeing up storage space for more important files. FileFusion is an innovative tool that can not be missed on any PC. Sooner or later, each hard disk is full. The clever tool clears up to 71% of disk space even with already cleaned hard disks. For this purpose, FileFusion relies on the new FileFusion technology, which is just awesome. On each PC there are many files, such as images or system files, which are available several times. This happens over time by itself and is also generated by Windows itself. Each file is located on the hard disk, with its own disk space, and is also displayed several times. The innovative FileFusion technology changes this inefficient approach, through the 3-stage process of deduplication.

Find Duplicate Files Automatically

A cluttered storage drive with numerous duplicate files can slow down your computer's performance. By removing duplicates, you can help optimize your system and improve its speed and responsiveness. In the first step, FileFusion starts an analysis of all files that are on the hard disk. FileFusion creates a digital fingerprint for each file and matches these prints with all other files to find duplicate files. Even if an identical file is named differently, FileFusion knows that it already exists in a different location on the hard disk. After FileFusion identifies duplicates, it deletes the disk space on the hard disk and instead creates a hard link that points to the remaining file. You won't notice any difference in your daily computer usage. Instead, there is a lot more space available! FileFusion makes all this automatically in the background. You need nothing more than to enable FileFusion. The hard disk is then analyzed and the cleaning performed automatically. If desired, you can also display a list of duplicates and decide for yourself which of them should be processed by FileFusion.

Free Up 71% Storage Space

Duplicate finder FileFusion helps you keep your files organized and reduce the chances of accidentally working with multiple versions of the same document, which can lead to confusion and errors. You wonder what happens when a file is deleted? Are all the other files deleted as well? Do not worry if a file is deleted, only the FileFusion reference (hardlink) will be deleted. Only when all references are deleted, the file is also permanently deleted on the hard disk. And what happens when a file is edited? In this case, the file stored on the hard drive remains unaffected. If a change is made, the reference is deleted and the edited file is stored as a stand-alone file on the hard disk. FileFusion allows up to 71% more storage space - absolutely secure and without risks.
