Junk files的意思

"Junk files" is a term used to describe unnecessary or unwanted files that accumulate on a computer over time. These files can include temporary files, cache files, cookies, browsing history, uninstalled program files, and other types of data that are no longer needed or serve no purpose.

Junk files can take up valuable space on your hard drive and can slow down your computer's performance. They can also contain sensitive information that you may not want to keep, such as old emails, temporary internet files, and deleted files that have not been removed from the computer's Recycle Bin.

To remove junk files from your computer, you can use a variety of methods, including using built-in utilities like Disk Cleanup in Windows or Cleanup in macOS, or using third-party software designed to clean and optimize your system. It's important to be careful when removing junk files, however, as some files may be needed by your computer or by certain programs, so be sure to only delete files that you are sure are safe to remove.
