It is faster and easier to work with a group of files than to work with them one at a time. Explain each part of the syntax diagram. The TYPE command allows you to display the contents of a file on the screen. TYPE is the command. If a file has an extension of .EXE, .COM, or .BAT it is executable.
Dummy files are files that contain no especially useful information.
Every file on a disk must have a unique name. Yet, when you make a copy of a file on the same disk, in a different subdirectory, it may have the same file name. While each file must have a unique name on the same drive and subdirectory, files that are in a different subdirectory may have identical names because the path makes those file names unique as the full name of the file includes the path and drive. The most common cause of lost files is when the file is written into the wrong disk or directory, or simply not saved correctly in the first place. In these cases the user will probably find the file eventually.
