22. Ch 622 The /P and /S Parameters with the DEL Command /P parameter with DEL command verifies prior to each file deletion.

23. Ch 623 The /P and /S Parameters with the DEL Command The /S parameter traverses the directory tree so files do not need to be deleted individually throughout disk structure.

24. Ch 624 The /P and /S Parameters with the DEL Command Again, DEL command syntax: DEL [/P] [/F] [/S] [/Q] [/A [[:] attributes]] names Names refers to [drive:] [path] filename

26. Ch 626 Changing File Names Rename file because: è File contents changed è Want the name for another file è File named incorrectly è You think of a better name

27. Ch 627 Changing File Names COPY command: è Create another file with same contents but a different name è End up with file and copy of file with another name

28. Ch 628 Changing File Names RENAME command: è Changes name of file - contents remain the same è End up with same file with a new name

29. Ch 629 Changing File Names RENAME command has two forms: è RENAME è REN

31. Ch 631 Changing File Names Renaming files: è Two step process in My Computer/Windows Explorer è One step process at command line

32. Ch 632 Activity—Using the REN Command to Rename Files KEY CONCEPTS: è When destination and *.* assumed è REN command vs. COPY command

33. Ch 633 Changing the Names of Subdirectories è Prior to Windows 95, REN command only worked with files. è Windows 95 REN command also used to rename subdirectories.

34. Ch 634 Changing the Names of Subdirectories Partial syntax for renaming subdirectories: REN [drive:] [path] [directoryname1] [directoryname2]

35. Ch 635 Activity—Using REN Command to Rename Subdirectories KEY CONCEPTS: è Command executed if no error message è Can rename subdirectories that are within other subdirectories

36. Ch 636 Using REN with Wildcards Multiple files on the same drive or directory that have a common element can be renamed using REN command with wildcards.

37. Ch 637 Activity—Using REN with Wildcards KEY CONCEPTS: è Compare ???.NEW with *.NEW è Renaming multiple files in same directory with one command

38. Ch 638 Using RENAME on Different Drives & Directories The REN command can be used to rename any file on any drive or directory.

39. Ch 639 Using RENAME on Different Drives & Directories Compare: è REN OLDFILE.EXT NEWFILE.EXT è REN B:OLDFILE.EXT NEWFILE.EXT è REN C:\JUNK\OLDFILE.EXT NEWFILE.EXT

40. Ch 640 Using RENAME on Different Drives & Directories è COPY - end up with two identical files in different locations. è REN - changes name of an existing file in a specific location.

41. Ch 641 Activity—Using Rename on Different Drives KEY CONCEPTS: è OS will not put a drive designator before new file name in REN è REN å Changes names not file contents å Does not move files è DIR vs. TYPE commands
