Disk Xray is a comprehensive disk management tool designed specifically for macOS. It integrates disk usage statistics analysis, duplicate file and folder finding, and system cleanup into one, aiming to help users efficiently manage storage space and optimize system performance.
Core Design Philosophy: Throughout all operations, Disk Xray provides extremely high security and reliability, ensuring users can safely recover even after accidentally deleting files.
Disk Xray primarily performs four core functional modules that together form a complete disk maintenance solution:
Reasons to choose Disk Xray include:
This module allows users to thoroughly uninstall any application. It precisely locates and deletes all configuration files, cache files, and auxiliary files related to the target application, ensuring the hard drive is not cluttered with redundant data and achieving a “clean uninstall.”
This is a visual disk space analysis tool. Whether for the entire hard drive or a specific subfolder, it provides a detailed categorized report of storage space usage. Users can drill down level by level to quickly identify folders that take up a lot of space and the files within them.
Helps users free up valuable disk space by finding and safely deleting duplicate files and folders, sometimes recovering several GB of capacity. The scan reveals copies of the same documents, photos, or other files scattered across the disk. All suspected duplicate files undergo strict byte-by-byte comparison to ensure 100% matching accuracy.
Improves computer speed by cleaning temporary files from the system. Its cleaning scope includes not only obvious areas like the “Trash” and “Downloads” folders but also many areas users may not know where to start, such as:
Additionally, the tool can scan and locate all large files on the disk. Users can flexibly set cleaning rules based on file age (e.g., one week, one month, or one year).

Installing Disk Xray for Mac v4.4 is very simple. Please follow the steps below to ensure the software is successfully activated and running.
Download the DMG image file of Disk Xray v4.4 from the link provided on this page. After downloading, double-click the DMG file to mount it. A disk icon named “Disk Xray” will appear on your desktop.
In the installation window that opens, you will see the Disk Xray application icon and a shortcut pointing to the “Applications” folder. Use your mouse to drag the Disk Xray icon directly onto the “Applications” folder icon on the right. The system will automatically perform the copy operation, completing the basic installation.
After installation, go to the “Applications” folder, find and double-click the Disk Xray icon. Since this is an application downloaded from the internet, macOS may display a security prompt. At this point, click “Cancel,” then go to “System Settings” > “Privacy & Security,” and find the “Open Anyway” button at the bottom of the page and click to confirm.
After the software launches, an activation window will pop up. Copy and paste the activation code or serial number provided with the installation package into the corresponding input field, and click the “Activate” button. After a few seconds, you will see an “Activation Successful” message. You can now use all features of Disk Xray for free.
Below are common questions and answers from users while using Disk Xray, hoping to help you quickly resolve any confusion.
Fully compatible. Disk Xray v4.4 has been natively optimized for Apple Silicon chips (including M1, M2, and M3 series). It also supports Intel-based Macs, ensuring smooth operation on all mainstream Mac hardware.
Very safe. The software performs strict byte-by-byte comparison before deleting files to ensure matching accuracy. Additionally, all files marked for deletion are first moved to the “Trash,” giving you room to undo. You can carefully preview the location and content of each file before final confirmation of deletion.
Scanning time depends on your hard drive capacity and the number of files. If your disk is over 1TB and contains many small files, the first scan may take 10-30 minutes. If the software appears frozen, please be patient, or try restarting the software and selecting only a specific folder for a smaller scan.
First, check whether the activation code you entered is complete, paying attention to case and hyphens. If it still shows as invalid after confirmation, the activation code may have been used on another device. Please contact us (contact information is at the bottom of this page), and we will provide you with a new valid activation code.
Manually dragging the application icon to the Trash only deletes the application itself but leaves behind a large number of configuration files, caches, and preference files. Disk Xray’s “Deep Uninstall” feature precisely locates and deletes all these hidden associated files, truly achieving a “clean uninstall” and freeing up more space.
No. Disk Xray uses a one-time purchase license. The activation code you purchased for v4.4 can be used permanently for all minor version updates within this major version. If a major version update like v5.0 is released in the future, an upgrade fee may be required.
Generally not. What is cleaned is useless cache, such as browser history and application crash logs. After this data is regenerated, application performance will not be affected. On the contrary, after cleaning up this redundant data, the overall system response speed will improve. It is recommended to clean once a month.
This is macOS’s security protection mechanism. Please follow Step 3 in the “Installation Tutorial”: first click “Cancel,” then go to “System Settings” > “Privacy & Security,” find and click “Open Anyway” at the bottom of the page to launch the software normally.
