  1. Chapter 6 Using DEL, REN, MOVE, and RD /S Ch 6

  2. Overview Will continue to work with internal commands that help manage and manipulate files. Ch 6

  3. Overview Will focus on the following commands: • DEL • REN • MOVE • RD /S Ch 6

  4. Overview Why and how to back up specific files, or an entire disk, so as to not lose important data will be discussed. Ch 6

  5. Eliminating Files with the DEL Command Keep only the files you need on your disk. Ch 6

  6. Eliminating Files with the DEL Command • DEL command used to erase unwanted files. • ERASE command works the same way DEL command works. Ch 6

  7. Eliminating Files with the DEL Command A file deleted at the command line is not physically removed from the disk. Ch 6

  8. Eliminating Files with the DEL Command • It is sometimes possible to recover a file deleted at the command line. • However, when DEL is used the file/s are deleted. Ch 6

  9. Eliminating Files with the DEL Command File deleted from hard drive using My Computer or WindowsExplorer is recoverable. Ch 6

  10. Eliminating Files with the DEL Command Files not recoverable are those deleted from: • Removable disk/s • Floppy disks • Command prompt Ch 6

  11. Eliminating Files with the DEL Command DEL command syntax: DEL [/P] [/F] [/S] [/Q] [/A [[:] attributes]] names Names refers to [drive:] [path] filename Ch 6

  12. Activity—Using the DEL Command KEY CONCEPTS: • Function of DIR • Why drive letter and path not included • DEL does not confirm prior to deletion Ch 6

  13. Deleting Multiple Files DEL can be used to delete multiple files. • Separate (by spaces) files to be deleted. Ch 6

  14. Activity—Using DEL with Multiple Parameters KEY CONCEPTS: • Using DIR • Deleting multiple files with DEL Ch 6

  15. Deleting Files on Other Drives and Directories The DEL command can be used to eliminate files on other drives and subdirectories. Ch 6

  16. Deleting Files on Other Drives and Directories DEL command syntax: DEL names Names refers to designated drives, subdirectories, and names of files you wish to delete. Ch 6

  17. Deleting Files on Other Drives and Directories Order and logic of syntax are important when keying in command. Ch 6

  18. Deleting Files on Other Drives and Directories • Common error: DEL GONE.FIL B: • Should be: DEL B:GONE.FIL Ch 6

  19. Activity—Using the DEL Command with Individual Files KEY CONCEPTS: • Using proper syntax • Use of second backslash • Using COPY gives two identically named files on different drives • DIR - shows file is there • DEL - deletes file Ch 6

  20. Using Wildcards with the DEL Command To delete many files at one time use wildcards with the DEL command. Ch 6

  21. Activity—Using the DEL Command KEY CONCEPTS: • Use DIR prior to global erase • Files deleted with DEL and wildcards not recoverable • Wildcards can be used when files are in subdirectory Ch 6

  22. The /P and /S Parameters with the DEL Command /P parameter with DEL command verifies prior to each file deletion. Ch 6

  23. 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. Ch 6

  24. 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 Ch 6

  25. Activity—Using /P and /S with the DEL Command KEY CONCEPTS: • Use of /P parameter • Use of /S parameter • Use of DIR command • Can use more than one parameter at a time Ch 6

  26. Changing File Names Rename file because: • File contents changed • Want the name for another file • File named incorrectly • You think of a better name Ch 6

  27. Changing File Names COPY command: • Create another file with same contents but a different name • End up with file and copy of file with another name Ch 6

  28. Changing File Names RENAME command: • Changes name of file - contents remain the same • End up with same file with a new name Ch 6

  29. Changing File Names RENAME command has two forms: • RENAME • REN Ch 6

  30. Changing File Names REN/RENAME syntax: REN [drive:] [path] [directoryname1 | filename1] [directoryname2 | filename2] Ch 6

  31. Changing File Names Renaming files: • Two step process in My Computer/Windows Explorer • One step process at command line Ch 6

  32. Activity—Using the REN Command to Rename Files KEY CONCEPTS: • When destination and *.* assumed • REN command vs. COPY command Ch 6

  33. Changing the Names of Subdirectories • Prior to Windows 95, REN command only worked with files. • Windows 95 REN command also used to rename subdirectories. Ch 6

  34. Changing the Names of Subdirectories Partial syntax for renaming subdirectories: REN [drive:] [path] [directoryname1] [directoryname2] Ch 6

  35. Activity—Using REN Command to Rename Subdirectories KEY CONCEPTS: • Command executed if no error message • Can rename subdirectories that are within other subdirectories Ch 6

  36. 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. Ch 6

  37. Activity—Using REN with Wildcards KEY CONCEPTS: • Compare ???.NEW with *.NEW • Renaming multiple files in same directory with one command Ch 6

  38. Using RENAME on Different Drives & Directories The REN command can be used to rename any file on any drive or directory. Ch 6

  39. Using RENAME on Different Drives & Directories Compare: • REN OLDFILE.EXT NEWFILE.EXT • REN B:OLDFILE.EXT NEWFILE.EXT • REN C:\JUNK\OLDFILE.EXT NEWFILE.EXT Ch 6

  40. Using RENAME on Different Drives & Directories • COPY - end up with two identical files in different locations. • REN - changes name of an existing file in a specific location. Ch 6

  41. Activity—Using Rename on Different Drives KEY CONCEPTS: • OS will not put a drive designator before new file name in REN • REN • Changes names not file contents • Does not move files • DIR vs. TYPE commands Ch 6

  42. Moving Files and Renaming Directories Review of commands: • MOVE used to rename a directory • REN/RENAME used to rename files and subdirectories Ch 6

  43. Moving Files and Renaming Directories MOVE command: • Move group of files or subdirectories - cannot change names • Move individual file/subdirectory - can change name of moved file or subdirectory • Move files/directories from one directory to another, from one drive to another Ch 6

  44. Moving Files and Renaming Directories Syntax to move one of more files: MOVE [/Y | /-Y] [drive:] [path] filename1 [,…] destination Ch 6

  45. Moving Files and Renaming Directories Syntax to rename a directory: MOVE [/y | /-y] [drive:] [path] dirname1 dirname2 Ch 6

  46. Activity—Moving Files & Renaming Directories KEY CONCEPTS: • Differences between syntax of MOVE and REN • When do you use MOVE? REN? • Move file in same drive/directory - eliminates first file and replaces contents of second file with contents of first file Ch 6

  47. Activity—Moving Files & Renaming Directories KEY CONCEPTS: • MOVE • Used instead of COPY, REN, DEL • Can act like COPY • Cannot change file names when used with wildcards • Cannot concatenate files • Can move entire subdirectory structure along with files with one command Ch 6

  48. RD /S Revisited Two ways to remove a directory: • RD (two-step process) • RD /S(one-step process) Ch 6

  49. Activity: Using RD and RD /S KEY CONCEPTS: • Using RD command • Using RD /S command Ch 6

  50. Backing Up Your DATA Disk • Always back up all data files. • Backing up application program disks can be tricky, especially copy-protected disks Ch 6
