This guide will detail its core interface, complete workflow, and practical tips. Whether you are a Mac novice or an experienced digital organizer, this tool can help you easily tackle the trouble of insufficient disk space. Below, we break down its features step by step to ensure you can use it right away.

I. Core Interface and Workspace Overview

After launching the software, the main interface is divided into the following functional areas:

1. Top Toolbar: Contains core action buttons such as “Add Scan Location”, “Start Scan”, “Smart Select”, “Delete”, “Merge Folders”, etc. These buttons follow the native macOS style and respond quickly, so you hardly feel interrupted during the cleaning process.
2. Left Navigation Panel:
   • Scan Location List: Displays added folders, drives, or photo libraries to be scanned. You can drag new folders into the list at any time, offering great flexibility.
   • Results Filter: After scanning, you can filter results by categories such as “All Duplicates”, “Duplicate Files”, “Similar Photos”, “Similar Audio”, “Similar Folders”, etc. This filter is very practical and helps you quickly focus on specific types of duplicate content.
   • Skip List: Manage files, folders, or file extensions you do not want scanned. For example, you can add system cache directories or large game files to avoid accidental scanning.
3. Central Main Workspace:
   • Before Scanning: Displays added scan locations and readiness status. You can confirm the scan scope at this time to avoid missing important directories.
   • During Scanning: Displays a dynamic progress bar, number of files scanned, and duplicates found. You can pause or stop at any time during scanning without affecting other operations.
   • After Scanning: Displays all found duplicates in a grouped list. Each group contains an “original” and multiple “copies”, with clear display of file path, size, modification date, etc. Grouping logic is based on content hash values to ensure accuracy.
4. Right Preview and Information Panel:
   • File Preview: Select any file to preview its content here (supports images, text, etc.). The preview supports zooming and full screen, making it easy to quickly confirm whether a file is important.
   • Detailed Information: Displays the full path, size, creation date, and other metadata of the selected file. This information is helpful for determining file origin.
   • Action Panel: Provides quick actions for the currently selected file or group, such as “Mark as Original”, “Show in Finder”, “Delete Permanently”, etc. The button layout is intuitive, reducing the risk of misoperation.
5. Bottom Status Bar: Displays scan statistics such as number of duplicate groups found, total files, and reclaimable space. This status bar updates in real time, giving you a clear view of cleaning results.

II. Complete Workflow: From Scanning to Cleaning

1. Create/Start a Scan Task

Step 1: Add Scan Locations

• Method: Click the + button in the top toolbar, or go to menu bar “File” > “Add Location”.
• Location: In the pop-up Finder window, select one or more folders, entire drives, or the “Photos” library. Supports adding external hard drives and network drives. If you have multiple external storage devices, you can add them all at once and the software will scan them in parallel.
• Shortcut: Cmd + O

Step 2: Configure Scan Options (Optional)

• Click “Settings” (gear icon) at the bottom of the left panel to adjust scan precision, whether to include hidden files, whether to exclude system files, etc. It is recommended to keep default settings for first use and fine-tune later based on actual needs.

Step 3: Start Scanning

• Method: Click the large “Scan” button in the top toolbar.
• Shortcut: Cmd + R
• After scanning starts, the central workspace displays dynamic progress. You can click the “Stop” button at any time to pause scanning. Scan speed depends on the number of files and disk type; SSDs are usually much faster than HDDs.

2. Review and Select Duplicates

After scanning is complete, all duplicates are listed by group.

Step 4: Browse and Preview Results

• Use the “Results Filter” on the left to switch between different types of results (e.g., duplicate files, similar photos).
• Click any group to expand and view all duplicate files within. Select an individual file to preview its content in the right panel.
• Quick Look: After selecting a file, press Space to use macOS Quick Look. This feature is especially suitable for quickly confirming image or document content.

Step 5: Select Copies to Delete

• Manual Selection: In each duplicate group, one file is marked as “original” by default (usually the earliest created or highest path priority). You can manually check the checkboxes of copies you wish to delete. Hold Shift or Cmd for multi-selection.
• Smart Auto-Selection:
  • Click the “Smart Select” button in the toolbar, and the software will automatically check suggested copies to delete based on your rules (e.g., “Always keep the earliest file”, “Always delete copies in Downloads folder”).
  • In “Settings” > “Auto Selection”, you can pre-configure folder priority rules for “Always Select” and “Never Select”. For example, you can set the “Documents” folder to “Always Keep” and the “Downloads” folder to “Always Delete”.
• Similar Photos/Audio Handling: For “Similar Photos” groups, the software displays similar images side by side. Click the “heart” icon below each image to mark it as the best to keep, and other images in the group will be automatically checked for deletion. This feature is especially suitable for cleaning duplicate photos imported from phones.

3. Process Selected Duplicates

Step 6: Execute Delete or Move Operations

• Delete to Trash: After confirming all copies to delete are checked, click the “Delete” button in the toolbar and select “Move to Trash”. This allows you to recover files before emptying the Trash.
• Delete Permanently: Click the “Delete” button and select “Delete Permanently”. This operation is irreversible, please use with caution. It is recommended only when you are certain.
• Move to Specified Folder: Click the dropdown arrow next to the “Delete” button and select “Move to Folder…” to move selected copies to a specified folder for archiving instead of deleting directly. This feature is suitable when you want to keep a backup but do not want it taking up space on the main drive.
• Shortcut: Delete to Trash Cmd + Delete

Step 7: Merge Folders

• Select “Similar Folders” view on the left, and the software will list pairs of folders with highly overlapping content.
• Select a pair of folders and click “Merge Folders” in the toolbar. You can choose:
  • Merge into New Folder: Merge all files from both folders into a brand new folder.
  • Move Unique Files: Move or copy files from folder B that do not exist in folder A into folder A. This is the most commonly used organization method, avoiding duplicate backups.

4. Completion and Export

Step 8: View Report and Recover (Optional)

• After deletion is complete, the software displays a confirmation list summarizing deleted files and freed space.
• If you accidentally delete something, you can immediately click “Undo” in the confirmation dialog, or later recover from Trash via menu bar “File” > “Restore Last Deleted Items”. It is recommended to review the confirmation list before emptying the Trash.

III. Advanced Tips for Common Features

1. Precisely Locate Large Duplicates: After scanning, click the “Size” column header in the results list to sort by file size in descending order. Prioritizing these large files is the most effective way to free up space. For example, a 5GB video file duplicated, cleaning it yields immediate results.
2. Use “Skip List” to Protect Important Files: Add folders containing important data (such as financial documents, project source code) or specific file extensions (such as .dmg) to the skip list to ensure they are never scanned or accidentally deleted. Configure once, effective long-term.
3. Set “Priority Folders” for Automatic Decisions: In “Settings” > “Auto Selection”, set the “Documents” folder to “Always Keep” and the “Downloads” folder to “Always Delete”. Then when using “Smart Select”, the software will automatically keep copies in “Documents” and delete copies in “Downloads”. This greatly improves cleaning efficiency.
4. Merge Folders to Organize Project Data: If you have multiple versions of project folders scattered on the desktop and in documents, use the “Similar Folders” feature to find them, then select “Move Unique Files” to consolidate all scattered files into one main folder, avoiding omissions. This is especially useful when organizing design drafts or code repositories.
5. Quickly Scan “Recent” Items: When adding scan locations, you can use macOS “Recents” items (such as “Recent Downloads”, “Recent Documents”) for quick targeted scanning. This is very efficient for cleaning temporary files or recently downloaded duplicate content.
