Why Can't You Delete/Empty Files from External Drive on Mac?

Before looking for solutions, it's important to know why your Mac might not want to let go of files saved on an external hard drive.

  • File Permission Issues: Many of the time, files on external drives may not be able to be deleted because they have limited rights. These files may appear on your Mac as "read-only," which means you can't delete them.
  • Corrupted File System: If the file system on the external hard drive is damaged, it can stop file processes from working normally. When you try to remove or move files, this could go wrong.
  • In-use Files: Files that are being used by programs or background processes may not be able to be deleted. The operating system on a Mac keeps current files safe so that you don't lose data or have problems with the system.
  • Drive Format Compatibility: NTFS, exFAT, FAT32, and Mac's native file system (APFS) are just a few file systems that can be used on portable hard drives. Problems with compatibility can make it hard to delete something.
  • Third-party Software Interference: If you install third-party programs or tools, they might get in the way of normal file management, making it impossible to delete files.
