Final answer:
To delete specific file types in a folder, you can use the command line or a file management tool.
Step-by-step explanation:
To delete specific file types in a folder, you can use the command line or a file management tool. If you are using a command line, you can use the 'del' command for Windows or the 'rm' command for Unix-based systems. For example, to delete all text files in a folder, you can use the command 'del *.txt' in Windows or 'rm *.txt' in Unix. If you prefer a file management tool, you can use software like File Explorer in Windows or Finder in macOS, which allows you to search for specific file types and delete them.
