TRANSCRIPT

  • Using DEL, REN, MOVE, and RD /S

    Ch 6

  • Overview

    Will continue to work with internal commands that help manage and manipulate files.

    Ch 6

  • Overview

    Will focus on the following commands: DEL REN MOVE RD /S

    Ch 6

  • 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

  • Eliminating Files with the DEL CommandKeep only the files you need on your disk.

    Ch 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

  • Eliminating Files with the DEL Command

    A file deleted at the command line is not physically removed from the disk.

    Ch 6

  • 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

  • Eliminating Files with the DEL CommandFile deleted from hard drive using My Computer or Windows Explorer is recoverable.

    Ch 6

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

    Ch 6

  • Eliminating Files with the DEL CommandDEL command syntax:DEL [/P] [/F] [/S] [/Q] [/A [[:] attributes]] names

    Names refers to [drive:] [path] filename

    Ch 6

  • ActivityUsing the DEL CommandKEY CONCEPTS: Function of DIR Why drive letter and path not included DEL does not confirm prior to deletion

    Ch 6

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

    Ch 6

  • ActivityUsing DEL with Multiple ParametersKEY CONCEPTS: Using DIR Deleting multiple files with DEL

    Ch 6

  • Deleting Files on Other Drives and Directories

    The DEL command can be used to eliminate files on other drives and subdirectories.

    Ch 6

  • 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

  • Deleting Files on Other Drives and Directories

    Order and logic of syntax are important when keying in command.

    Ch 6

  • Deleting Files on Other Drives and Directories

    Common error:DEL GONE.FIL B:

    Should be: DEL B:GONE.FIL

    Ch 6

  • ActivityUsing the DEL Command with Individual FilesKEY CONCEPTS:Using proper syntaxUse of second backslashUsing COPY gives two identically named files on different drivesDIR - shows file is thereDEL - deletes file

    Ch 6

  • Using Wildcards with the DEL Command

    To delete many files at one time use wildcards with the DEL command.

    Ch 6

  • ActivityUsing the DEL CommandKEY CONCEPTS:Use DIR prior to global eraseFiles deleted with DEL and wildcards not recoverableWildcards can be used when files are in subdirectory

    Ch 6

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

    Ch 6

  • 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

  • The /P and /S Parameters with the DEL CommandAgain, DEL command syntax:DEL [/P] [/F] [/S] [/Q] [/A [[:] attributes]] names

    Names refers to [drive:] [path] filename

    Ch 6

  • ActivityUsing /P and /S with the DEL CommandKEY CONCEPTS:Use of /P parameterUse of /S parameterUse of DIR commandCan use more than one parameter at a time

    Ch 6

  • Changing File NamesRename file because: File contents changed Want the name for another file File named incorrectly You think of a better name

    Ch 6

  • Changing File NamesCOPY command:Create another file with same contents but a different nameEnd up with file and copy of file with another name

    Ch 6

  • Changing File NamesRENAME command:Changes name of file - contents remain the sameEnd up with same file with a new name

    Ch 6

  • Changing File NamesRENAME command has two forms: RENAME REN

    Ch 6

  • Changing File Names

    REN/RENAME syntax:

    REN [drive:] [path] [directoryname1 | filename1] [directoryname2 | filename2]

    Ch 6

  • Changing File Names

    Renaming files:Two step process in My Computer/Windows ExplorerOne step process at command line

    Ch 6

  • ActivityUsing the REN Command to Rename Files

    KEY CONCEPTS: When destination and *.* assumed REN command vs. COPY command

    Ch 6

  • 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

  • Changing the Names of Subdirectories

    Partial syntax for renaming subdirectories:

    REN [drive:] [path] [directoryname1] [directoryname2]

    Ch 6

  • ActivityUsing REN Command to Rename SubdirectoriesKEY CONCEPTS:Command executed if no error message Can rename subdirectories that are within other subdirectories

    Ch 6

  • 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

  • ActivityUsing REN with WildcardsKEY CONCEPTS:Compare ???.NEW with *.NEWRenaming multiple files in same directory with one command

    Ch 6

  • Using RENAME on Different Drives & Directories

    The REN command can be used to rename any file on any drive or directory.

    Ch 6

  • Using RENAME on Different Drives & DirectoriesCompare:REN OLDFILE.EXT NEWFILE.EXT

    REN B:OLDFILE.EXT NEWFILE.EXT

    REN C:\JUNK\OLDFILE.EXT NEWFILE.EXT

    Ch 6

  • 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

  • ActivityUsing Rename on Different DrivesKEY CONCEPTS:OS will not put a drive designator before new file name in RENREN Changes names not file contents Does not move filesDIR vs. TYPE commands

    Ch 6

  • Moving Files and Renaming Directories

    Review of commands:MOVE used to rename a directoryREN/RENAME used to rename files and subdirectories

    Ch 6

  • Moving Files and Renaming DirectoriesMOVE command:Move group of files or subdirectories - cannot change namesMove 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

  • Moving Files and Renaming Directories

    Syntax to move one of more files:

    MOVE [/Y | /-Y] [drive:] [path] filename1 [,] destination

    Ch 6

  • Moving Files and Renaming DirectoriesSyntax to rename a directory:

    MOVE [/y | /-y] [drive:] [path]dirname1 dirname2

    Ch 6

  • ActivityMoving Files & Renaming DirectoriesKEY CONCEPTS:Differences between syntax of MOVE and RENWhen 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

  • ActivityMoving Files & Renaming DirectoriesKEY CONCEPTS: MOVE Used instead of COPY, REN, DELCan act like COPYCannot change file names when used with wildcardsCannot concatenate filesCan move entire subdirectory structure along with files with one command

    Ch 6

  • RD /S RevisitedTwo ways to remove a directory: RD (two-step process) RD /S (one-step process)

    Ch 6

  • Activity: Using RD and RD /SKEY CONCEPTS: Using RD command Using RD /S command

    Ch 6

  • 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

  • Backing Up Your DATA Disk

    Special operating commands and procedures must be used to back up a hard disk.

    Ch 6

  • Backing Up Your DATA Disk

    Three ways to back up data files: DISKCOPY COPY XCOPY

    Ch 6

  • Backing Up Your DATA DiskNever use the MOVE command for backup purposes.

    Ch 6

  • Backing Up Your DATA DiskDevelop a regular backup routine. Can use tape backup. Use writable CD if availableMessage is BACK UP DATA FILES

    Ch 6

  • Backing Up Your DATA DiskApplication programs can usually be reinstalled from original disks.

    Ch 6

  • ActivityBacking Up with the DISKCOPY CommandKEY CONCEPTS:How to not accidentally copy hard driveUse DISKCOPY - get 2 copies of DATA disk

    Ch 6

  • ActivityBacking Up with the DISKCOPY CommandBackup disk Keep current Have two or more Check backup disk regularly Some organizations need to recreate records Need archival backup Need transaction history

    Ch 6

  • Backing Up Files with the COPY CommandDISKCOPY: Backs up entire floppy disk Formats new disk

    Ch 6

  • Backing Up Files with the COPY CommandCOPY:Used to backup specific filesCopy files from one floppy to anotherDoes not format new diskMust not be used to copy all files from hard disk to floppy

    Ch 6

  • Backing Up Files with the COPY CommandDo regular backups:Back up files that have changed or are new

    Ch 6
