Как отображать и изменять расширения файлов в Windows 11?

File extensions are the letters that appear at the end of a file name, such as .jpg, .mp4, .pdf, or .docx. They help Windows identify the file type and determine which program should open it. However, in Windows 11, file extensions are hidden by default for many common file types. While this may simplify the interface, it can make it harder to identify files or manage different formats.

Showing file extensions allows users to quickly recognize file types, organize files more efficiently, and avoid opening potentially unsafe files disguised with misleading names. It is also helpful when you need to modify or change file extensions during file conversion or organization.
