What are file extensions?
File extensions are suffix added to file names to indicate the file type. They are used by operating systems to identify the format and nature of the files. Each file extension has a specific meaning and determines which program should be used to open and manipulate the file.
Why are file extensions important?
File extensions play a key role in organizing and managing files on a computer. They allow the operating system to recognize the file type and automatically associate the appropriate program to open it. This facilitates location and access to files, as well as ensuring that they are opened correctly.
Examples of file extensions
There are numerous file extensions, each corresponding to a specific file type. Here are some common examples:
- .txt : Simple text files;
- .docx : Microsoft Word documents;
- .xlsx : Microsoft Excel spreadsheets
- .JPG or .JPEG : images in JPEG format;
- .mp3 : audio files;
- .mp4 : Video files;

How to change the extension of a file?
In some cases, it may be necessary to change the extension of a file. This can be done manually, renamed the file and replacing the extent with another. However, it is important to be careful in doing so, as changing the extension of a file can make it inaccessible or unusable if the associated program cannot recognize it.
Conclusion
File extensions are essential elements for identifying and managing different file types. They allow the operating system to recognize the file format and associate the appropriate program to open it. Knowing the most common file extensions can help better understand how files are organized and manipulated on a computer.
