In-Depth Review & Features
Key Features
- Content-Based Scanning: Compares actual file contents to find exact duplicates, bypassing different file names for higher accuracy.
- Advanced Media Search: Identifies duplicate music using tags (Album, Artist, Bitrate) and detects similar photos even if they are flipped, rotated up to 180 degrees, or converted to other formats.
- Data Protection Mechanism (DPM): Automatically steps in if you accidentally select all files in a group, unchecking and keeping at least one original file to prevent data loss.
- Folder Comparison: Compares source and target folders to identify same, different, or additional files—ideal for checking manual backups.
- File Organizer Add-on: Allows you to restructure your hard disk by moving or copying files into unique folder structures based on creation dates.
- Flexible Action Controls: Choose to permanently delete duplicates, move them to a specific folder, rename them with prefixes/suffixes, or replace them with shortcuts.
- Session Management: Save your scan configurations and session progress to resume large operations later without having to rescan your entire drive.

Frequently Asked Questions
How can I get a valid free license key?
You can get a 100% legal free license key from WinningPC during our limited-time giveaway campaigns.
How does the software ensure I don’t delete important files?
It uses a Data Protection Mechanism that automatically keeps at least one file unchecked in a duplicate group. You can also use the Excluded Files List to ignore specific folders.
Does the scan work if my music files are missing tags?
By default, the program skips music files without tags during a “Music Search.” However, you can change the settings to compare the actual file content instead.
Can I stop a scan halfway and finish it another day?
Yes. The Save Session feature allows you to exit the application and reload your duplicate results later without rescanning your storage.
