The command 'Command-I' is a keyboard shortcut that displays the info window for a file in macOS. This window provides detailed information about the selected file or folder, such as its size, location, date of creation, permissions, and more. This is a helpful tool for users to quickly access specific metadata associated with their files without needing to open the file itself.

The other options do not align with the function of 'Command-I'. For example, opening a file in an editor is typically done through different commands depending on the application in use. Initializing disk formatting involves a separate procedure entirely and is not related to viewing file information. Lastly, increasing file size is not a function of any command prompt in macOS; rather, file size is determined by the data contained within the file.
