An ALL-IN-ONE Duplicate File Finder for Windows 10

Where are duplicate files from on Windows 10?

Duplicate files on your disk will take up much available disk space, slowing your computer performance. Duplicate files on a computer can originate from various sources and causes:

Manual copying: Users often manually copy files or folders without realizing the same content already exists in another location. This can happen when people want to back up files or organize data.

File synchronization: File synchronization tools, cloud storage services, or backup software can sometimes create duplicate files if not configured correctly. They might make copies of files during the syncing process.

Software updates: When you update software, sometimes the installer creates backup copies of files to ensure a rollback option is available. These backup copies can become duplicates.

File restore: After a system restore or data recovery process, you might end up with duplicate files if the restoration process isn't careful about file deduplication.

So, it's essential to periodically clean up duplicate files to free up storage space and maintain a more organized and efficient computer system.
