35. Ch 535 The TYPE Command TYPE command syntax: TYPE [drive:] [path] filename

36. Ch 536 Activity—Displaying Files Using TYPE Command KEY CONCEPTS: è Text files/ASCII files è Recognizing executable code files by file extensions è Support files è Format - how data is arranged

37. Ch 537 Dummy Files Dummy files: è Files without particular meaning è Usually created for test purposes è Usually smaller and are samples

38. Ch 538 Activity—Using the Copy and Type Commands KEY CONCEPTS: è TYPE can use more than one parameter è DIR - displays current files on disks è TYPE - displays contents of one file at a time

39. Ch 539 Making Additional Files on the Same Disk Can have two files with identical contents on same disk: è Including same name - if files kept in different subdirectories è In same subdirectory - if the names of the files are different.
