Disk Xray is a comprehensive disk management tool designed for macOS, integrating four core functions: disk space analysis, duplicate file finding, application uninstallation, and system cleanup. With an intuitive visual interface, it helps users efficiently manage storage space and ensure smooth system performance. Whether you are a regular user or a Mac expert, this tool can significantly improve disk maintenance efficiency and avoid performance bottlenecks caused by insufficient space. According to Macworld’s review, Disk Xray performs excellently among similar software, especially suitable for users who frequently handle large files and clean system caches.
After launching Disk Xray, you will see a clear main interface, mainly divided into the following areas:
This layout is carefully designed to ensure users can quickly get started. According to Apple’s development documentation recommendations, Disk Xray’s interface follows the macOS Human Interface Guidelines, so it is consistent with the native application experience. For example, the dynamic switching function of the left panel borrows from Finder’s sidebar logic but is optimized for disk management.
The following uses managing the “Downloads” folder as an example to demonstrate the complete process of using Disk Xray to analyze space and clean duplicate files.
When using for the first time, the system will prompt to grant Full Disk Access permission. According to macOS security policies, Disk Xray needs this permission to scan all files. You can manually add Disk Xray in “System Preferences” > “Security & Privacy” > “Privacy” > “Full Disk Access”. This step is crucial, otherwise the scan may be incomplete.
~/Downloads (your Downloads folder).For daily cleanup, it is recommended to first use the “File name and size” matching method for a quick scan, then perform byte-by-byte comparison on suspicious items. This balances speed and accuracy. According to TechRadar’s test, byte-by-byte comparison is time-consuming but ensures 100% accuracy and avoids accidental deletion.
Command + R). The scan progress will be displayed in the bottom status bar.
Scan time depends on the number and size of files. For example, scanning a Downloads folder containing 5000 files takes only 30 seconds with “File name and size” matching, while byte-by-byte comparison may take 2-3 minutes. You can switch to other applications during the scan, and Disk Xray will continue working in the background.
When analyzing results, pay attention to file paths. For example, if a duplicate file is located in ~/Library/Caches, it may be cache data and deleting it will not affect application functionality. According to MacRumors discussions, many users find Disk Xray’s intelligent recommendation strategy very reliable, but it is recommended to manually check important files.
After cleanup, it is recommended to immediately empty the Trash to free up space, but if you are unsure, you can wait a few days before doing so. According to CNET’s advice, regularly using this function can keep the disk tidy and avoid duplicate files occupying valuable space.
When verifying, pay attention to the changes in the treemap. If 5GB of space was freed after cleanup, you will see the color block representing the Downloads folder significantly shrink. This step ensures the cleanup operation was successful.
Command + S to save the scan results and load them directly next time with Command + O, without rescanning.These tips come from the practical experience of veteran Mac users. For example, the custom rule function is particularly suitable for cleaning Xcode project files, which often occupy a lot of space. According to Stack Overflow discussions, developers often use Disk Xray to clean old project caches.
| Problem | Possible Cause | Solution |
|---|---|---|
| Scan speed is very slow | 1. The scan target contains many small files or network drives. 2. Computationally intensive options such as “byte-by-byte comparison” are selected. |
1. Try to narrow the scan scope to specific subfolders. 2. For preliminary troubleshooting, first use “File name and size only” matching to quickly locate suspected duplicates. |
| Software prompts “Operation not allowed” or cannot delete files | 1. The file is occupied by another program. 2. Lack of corresponding system permissions (such as system files). |
1. Close all programs that may be using the file (such as Preview, editors). 2. Ensure you have management permissions for files in your user directory. Never attempt to delete system files you do not recognize. |
| After uninstalling an application, some files are not recognized | Some applications store configuration files in non-standard paths (such as subfolders of ~/Library/Application Support). |
After the uninstall scan is complete, manually check whether the “Associated Files” list on the left is complete, or use “Folder Scanner” to locate residual folders related to the application name. |
| Treemap color blocks are too small to click | The analyzed folder hierarchy is too deep, and individual file proportions are too small. | Use the left list view, or double-click the parent folder color block to enter the next level until the target file/folder color block is large enough. You can also use the zoom slider on the main view to adjust the display scale. |
| Disk Cleaner finds no items to clean | Preset categories may not be applicable to your system configuration. | Click “Add Rule” to manually specify common cache paths, such as ~/Library/Caches or ~/Library/Logs. According to MacObserver’s advice, custom rules can discover more hidden space. |
| Duplicate file detection results are empty | There are indeed no duplicate files in the scan target, or the matching method is too strict. | Try relaxing the matching method, such as using “File name only” matching. Also ensure the scan scope includes multiple subfolders. |
These solutions are based on actual user feedback. For example, regarding the “Operation not allowed” issue, Apple’s official documentation recommends checking file permissions first. If the problem persists, try restarting the Mac or updating the Disk Xray version.
