If you’ve ever transferred files to a USB drive on your Mac, you may have noticed that some files seem to be hidden from plain view. These hidden files can take up valuable storage space and sometimes cause headaches when trying to manage your data. In this article, we will explore the methods to delete these hidden files from your USB on a Mac, ensuring that your data remains tidy and accessible.
Understanding Hidden Files On Your USB Drive
Before diving into the process of deletion, it’s essential to understand what hidden files are and why they exist on your USB drive. Hidden files are not visible in regular file browsing environments. On a Mac, these files usually store system-related data or user configurations that applications need to run, but they can also accumulate unnecessary junk over time.
The Mac operating system typically hides these files to prevent accidental deletion, which could lead to malfunctions in applications. However, there can be instances when these files become unwanted clutter, prompting the need for removal.
Identifying Hidden Files On Your USB Drive
To manage hidden files effectively, the first step is to identify them. There are various methods to view hidden files on your USB. Here are two easy ways:
- Keyboard Shortcut: Open Finder, navigate to the USB drive, and press Command + Shift + . (period). This will toggle the visibility of hidden files.
- Terminal Command: If you prefer using the Terminal, you can view hidden files by entering the command defaults write com.apple Finder AppleShowAllFiles true, followed by killall Finder. This command will restart Finder and make all hidden files visible.
Once you can see hidden files, it’s crucial to know what to delete and what to keep. As a rule of thumb, avoid deleting hidden files related to system operations unless you are sure they are unnecessary.
How To Delete Hidden Files From Your USB Drive
Now that you have successfully identified the hidden files, you can proceed to delete them. There are several methods to remove these files safely.
Method 1: Using Finder
Deleting hidden files via Finder is straightforward and user-friendly:
-
Show Hidden Files: As mentioned earlier, use the keyboard shortcut Command + Shift + . while in Finder to display the hidden files on your USB drive.

Select the Hidden Files: Navigate through your USB drive to find the hidden files you wish to delete. You will notice these files appear slightly grayed out compared to regular files.
-
Delete Selected Files: Click on the hidden file you want to delete, then press Command + Delete, or right-click on the file and select “Move to Trash.”
-
Empty the Trash: Don’t forget to empty the Trash to permanently remove the files. Right-click on the Trash icon in your Dock and select “Empty Trash.”
Method 2: Using Terminal
If you are comfortable using command-line tools, Terminal is a powerful way to delete hidden files:
