File Extension
A file extension is a suffix added to the end of a filename in a hierarchical file system to denote the file's type (e.g., .txt, .jpg, .exe). It serves the following purposes:
1. File Type Identification:
- The file extension helps the operating system and applications recognize the file type and determine how to open or process it.
- For example, .txt indicates a text file, .jpg is an image, and .exe is an executable file.
2. File Association:
- Each file extension is associated with specific applications that can handle that file type.
- When you double-click a file with a certain extension, the system opens the default associated application.
3. Content Encoding:
- Some file extensions, like .gz and .zip, indicate that the file is compressed or encoded.
- These extensions allow the system to automatically decompress or encode the file when needed.
4. Security:
- File extensions can also provide clues about potential security risks.
- For example, .exe files can contain malicious code, and .vbs files can be used to execute scripts.
Examples:
| File Extension | File Type |
|---|---|
| .txt | Text file |
| .jpg | JPEG image |
| .exe | Executable file |
| .zip | Compressed file |
| .pdf | Portable Document Format file |
| .docx | Microsoft Word document |
| .mp4 | MPEG-4 video file |
| .html | HyperText Markup Language file |
Importance of File Extensions:
File extensions are essential for:
- Efficient file management and organization
- Correct file handling by applications
- Ensuring compatibility and interoperability across different systems
- Detecting potential security threats
