84 Learning the Basics Saving your work 2 Choose the drive and folder where you want your file to be stored. 3 Type a file name, then click Save. HINT: To make another copy of the file you are currently working with, choose Save As from the File menu and give the new file a different name. File names The Windows operating system supports long file names that can contain up to 255 characters, and can include spaces. Some applications still require file names limited to eight characters. You may use all the letters and numbers on the keyboard plus these characters and '. File names are not case-sensitive. Using a file extension Most programs assign an extension to the file name that identifies the file as being created in the program with a particular format. For example, Microsoft Word saves files with a .doc extension. Any file name with an extension of ".doc" is assumed to be a Microsoft Word file. Creating your own extension is usually unwise, since the program is unlikely to recognize a strange extension and may refuse to handle your file correctly. TECHNICAL NOTE: By default, the Windows® operating system does not show file extensions. For information on showing or hiding file extensions, see your Windows® operating system online Help.
