• Content-Based Search. The application compares files using binary content analysis, ensuring that only files with exactly matching content are identified as duplicates, regardless of name or location. This bit-level verification prevents false positives and ensures accuracy in the results.
• Multiple Comparison Criteria. The software allows configuring specific search parameters, including excluding system files, skipping files based on minimum size, or considering modification dates. Users can define specific folders to include or exclude from the analysis.
• Organized Results View. Detected duplicate files are presented in clear groups with detailed information about size, location, and modification date. The interface shows previews for certain file types, making it easier to visually identify content before making deletion decisions.
• Intelligent Duplicate Selection. The algorithm automatically suggests which files to delete based on criteria such as modification date, location, or file attributes. Users can review and modify these selections before proceeding with deletion.
• Safe Deletion with Confirmation. The deletion process includes multiple verification steps to prevent accidental data loss. Options include moving to the Recycle Bin or permanent deletion, with clear warnings when potentially important files are selected.
• Customizable Filters. Users can define specific file types to search for, such as images, documents, audio, or video. Filters allow specifying custom file extensions and size ranges for targeted search approaches.
• Recoverable Space Analysis. The tool calculates and displays the total amount of disk space that can be freed by deleting the identified duplicates. This metric is presented both before and after the file selection process for deletion.
• Automatic Operation Backup. The application generates detailed logs of all actions performed, including information about deleted files and their original locations. These logs allow reviewing past operations and recovering files if necessary.
• Quick and Full Scan Modes. The software offers different analysis levels, from a superficial check to a thorough content comparison. The full mode performs additional verifications for large files or those with partial similarities.
• Windows Explorer Integration. The application includes context menu options that allow starting duplicate searches directly from selected folders in File Explorer. This integration streamlines the workflow for frequent users.
• Scheduled Automated Tasks. The tool allows configuring periodic duplicate file searches that run automatically according to a defined schedule. These scheduled tasks can be executed during periods of low system activity.
• Persistent Exclusion Management. Users can create persistent lists of folders, file types, or specific files that should be ignored in all future scans. These exclusions are maintained across sessions and software updates.
• Metadata Comparison. In addition to content, the application can verify similarities in metadata such as EXIF in images, ID3 in audio, or document properties. This capability allows identifying duplicates that have been renamed but retain identical information.
• Detailed Progress Indicators. During scanning, the interface displays accurate information about elapsed time, estimated remaining time, and the number of files processed. These indicators allow assessing the duration of extensive operations.
• Portable Mode Available. The application offers a version that can be run from removable media without installation on the system. This variant retains all core functionalities without leaving permanent configurations on computers.
