Expert Tips

Quick Start: Finding Exact Duplicates

1. On the Home tab, click New Scan to start with default settings.
2. Navigate to the Scan Criteria tab and ensure Regular Mode is selected.
3. Under Regular Mode, check the Same Content option (using MD5, SHA-1, or byte-to-byte comparison) for the most accurate results.
4. Go to the Scan Location tab and drag the folders or drives you wish to scan into the Folders to Search pane. Avoid scanning Windows system folders.
5. Click Start Scan to begin the process.

Reason To Do This: Starting with a Same Content scan in Regular Mode is the most reliable way to find identical files, regardless of their names or dates. This ensures you’re deleting true duplicates and not just similarly named but different files. Excluding system folders prevents accidental damage to your operating system.

Using the Selection Assistant for Smart Deletion

1. After a scan is complete, go to the Duplicate Files tab to review the results.
2. Utilize the Selection Assistant (often found in the toolbar or right-click menu) to automatically mark files for deletion.
3. Choose a selection rule, such as Mark All but One in Each Group, Select Oldest Files, Select Newest Files, or Select Files Outside a Specific Folder.
4. Review the marked files before proceeding with deletion to ensure you are keeping the desired copies.

Reason To Do This: The Selection Assistant streamlines the tedious task of manually marking duplicates. By applying intelligent rules, you can quickly and safely select files to remove, saving significant time and reducing the risk of deleting important originals.

Protecting Important Files and Folders

1. Before starting a scan, navigate to the Scan Location tab.
2. Identify any critical folders (e.g., Originals or system directories) that you wish to protect from deletion.
3. Use the Exclude or Protected folder options within Duplicate Cleaner to ensure files in these locations are not flagged for removal or are handled with extra caution.
4. Consider moving deleted files to the Recycle Bin or a temporary archive folder first, rather than permanent deletion, for an extra layer of safety.

Reason To Do This: Protecting specific folders and using the Recycle Bin as an intermediary step are crucial safeguards. This prevents accidental deletion of essential system files or your original, irreplaceable documents and media, allowing for recovery if a mistake is made.
