What's the File Extension?

A File Extension is a suffix added to the end of a filename to indicate the format or type of a file. It is typically composed of a few characters and helps both users and software understand the content and behavior of the file. In the context of the Dummy Type, it represents a placeholder for generating file extensions used for testing and development purposes.

What's considered valid format for File Extension?

Valid file extensions are short, descriptive, and usually consist of letters or numbers. Common examples include '.txt' for text files, '.jpg' for image files, and '.mp3' for audio files.

  • .txt
  • .jpg
  • .mp3
  • .html

What's considered invalid format for File Extension?

Invalid file extension formats can include:

  • Using long or cryptic file extensions (e.g., '.datafile').
  • Using special characters not commonly found in file extensions.
  • Not including a dot before the extension (e.g., 'txt' instead of '.txt').
