如何在我的Mac上找到大文件？

要釋放Mac存儲空間，可使用三種方法查找和處理大文件：1. 使用系統自帶的存儲管理工具，在“關於本機”-“存儲”中查看“大文件”列表；2. 在Finder中設置文件大小和修改時間等條件搜索大文件；3. 利用第三方工具如DaisyDisk、OmniDiskSweeper或GrandPerspective掃描並可視化磁盤佔用情況。每種方法各有優勢，系統工具方便快捷，Finder提供更精確搜索選項，第三方軟件則提供更強分析功能，刪除後記得清空廢紙簍以免殘留佔空間。

如果你're trying to free up space on your Mac, finding and dealing with large files is a good place to start. It's not always obvious where those big files are hiding — they could be old videos, downloads, or even app caches. The good news is, there are several straightforward ways to locate them without needing any technical expertise.

Use the Built-in Storage Management Tool

macOS has a handy feature built right into the system that helps you see what's taking up space.

• Go to Apple menu > About This Mac > Storage , then click Manage .
• From there, you'll see categories like Large Files , Documents , Apps , etc.
• Click on Large Files and macOS will show you a list of the biggest files across your user account, including documents, movies, and application support files.

This method doesn't require any extra software and gives you a clear picture of what's eating up your disk space. Just keep in mind it might not show system files or files from other user accounts.

Search in Finder for Large Files

If you want more control or need to dig deeper, Finder can help too.

• Open a new Finder window and hit Command F to start a search.
• In the search bar, click the button and choose File size from the dropdown.
• Set it to is greater than and type something like 500 MB (you can adjust this number based on your needs).
• You can also add another condition by clicking again and choosing Last opened date or Date last modified to find older large files.

Finder's search can take a few seconds to load all results, especially if you have a lot of files. Once loaded, you can sort by size or kind to make browsing easier.

Try Third-Party Tools for More Control

If you want more powerful features — like scanning your entire drive or visualizing file sizes with charts — third-party tools can help.

Some popular options include:

• DaisyDisk – shows a color-coded map of your disk usage and lets you delete files directly
• OmniDiskSweeper – a free tool from The Omni Group that shows folder sizes and lets you drill down
• GrandPerspective – open-source and visually intuitive, great for seeing which folders are taking up space

These apps typically scan your drive and give you a block diagram where bigger blocks mean larger files or folders. They're especially useful if you're not sure where to look or if the built-in tools don't go deep enough.

Keep in mind that after deleting large files, especially using third-party tools, it's a good idea to empty your Trash regularly — some deleted files still take up space until you do. Also, avoid deleting system or app files unless you know what you're doing.

基本上就這些。
