Should you have to type in the file extension when saving a file?

Whether you should have to type in the file extension when saving a file depends on the software and operating system being used. Many modern applications automatically append the appropriate file extension based on the chosen file format, making it unnecessary for users to type it manually. However, in some cases, especially with less common formats or certain programming environments, specifying the extension can ensure compatibility and correct file recognition. Overall, user experience and efficiency often dictate that manual entry of the extension is not required.
