Keep only the files you need on your disk.
Ch 6 6
Eliminating Files with Eliminating Files with the DEL Commandthe DEL Command
DEL command used to erase unwanted files.
ERASE command works the same way DEL command works.
Ch 6 7

A file deleted at the command line is not physically removed
from the disk.
Ch 6 8
Eliminating Files with Eliminating Files with the DEL Commandthe 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 Eliminating Files with the DEL Commandthe DEL Command
File deleted from hard drive using My Computer or Windows Explorer is
recoverable.
Ch 6 10

DEL command syntax:DEL [/P] [/F] [/S] [/Q] [/A [[:]
attributes]] names
Names refers to [drive:] [path] filename
Ch 6 12
Activity—Using the Activity—Using the DEL CommandDEL 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 FilesDeleting Multiple Files
DEL can be used to delete multiple files.
Separate (by spaces) files to be deleted.
Ch 6 14
Activity—Using DEL with Activity—Using DEL with Multiple ParametersMultiple Parameters
KEY CONCEPTS: Using DIR Deleting multiple files with DEL
Ch 6 15
Deleting Files on Other Deleting Files on Other Drives and DirectoriesDrives and Directories
The DEL command can be used to eliminate files on other drives and subdirectories.
Ch 6 16
Deleting Files on Other Deleting Files on Other Drives and DirectoriesDrives 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 Deleting Files on Other Drives and DirectoriesDrives and Directories
Order and logic of syntax are important when keying in
command.
Ch 6 18
Deleting Files on Other Deleting Files on Other Drives and DirectoriesDrives and Directories
Common error:DEL GONE.FIL B:
Should be: DEL B:GONE.FIL
Ch 6 19
Activity—Using the DEL Activity—Using the DEL Command with Individual Command with Individual
FilesFilesKEY 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 Using Wildcards with the DEL CommandDEL Command
To delete many files at one time use wildcards with the DEL
command.
Ch 6 21
Activity—Using the Activity—Using the DEL CommandDEL 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 The /P and /S Parameters with the DEL Commandwith the DEL Command
/P parameter with DEL command verifies prior to
each file deletion.
Ch 6 23
The /P and /S Parameters The /P and /S Parameters with the DEL Commandwith 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 The /P and /S Parameters with the DEL Commandwith 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 Activity—Using /P and /S with the DEL Commandwith 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 NamesChanging 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 NamesChanging 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 NamesChanging 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 NamesChanging File Names
RENAME command has two forms:
RENAME REN
Ch 6 30
Changing File NamesChanging File Names
REN/RENAME syntax:
REN [drive:] [path]
[directoryname1 | filename1]
[directoryname2 | filename2]
Ch 6 31
Changing File NamesChanging File Names
Renaming files:Two step process in My
Computer/Windows ExplorerOne step process at command line
Ch 6 32
Activity—Using the REN Activity—Using the REN Command to Rename FilesCommand to Rename Files
KEY CONCEPTS: When destination and *.* assumed REN command vs. COPY command
Ch 6 33
Changing the Names Changing the Names of Subdirectoriesof 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 Changing the Names of Subdirectoriesof Subdirectories
Partial syntax for renaming subdirectories:
REN [drive:] [path] [directoryname1] [directoryname2]
Ch 6 35
Activity—Using REN Activity—Using REN Command to Rename Command to Rename
SubdirectoriesSubdirectories
KEY CONCEPTS: Command executed if no error
message Can rename subdirectories that are
within other subdirectories
Ch 6 36
Using REN with Using REN with WildcardsWildcards
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 Activity—Using REN with Wildcardswith Wildcards
KEY CONCEPTS: Compare ???.NEW with *.NEW Renaming multiple files in same
directory with one command
Ch 6 38
Using RENAME on Different Using RENAME on Different Drives & DirectoriesDrives & Directories
The REN command can be used to rename any file on
any drive or directory.
Ch 6 39
Using RENAME on Different Using RENAME on Different Drives & DirectoriesDrives & 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 Using RENAME on Different Drives & DirectoriesDrives & 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 Activity—Using Rename on Different Driveson 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 Moving Files and Renaming DirectoriesRenaming Directories
Review of commands: MOVE used to rename a directory REN/RENAME used to rename files
and subdirectories
Ch 6 43
Moving Files and Moving Files and Renaming DirectoriesRenaming 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 Moving Files and Renaming DirectoriesRenaming Directories
Syntax to move one of more files:
MOVE [/Y | /-Y] [drive:] [path] filename1 [,…] destination
Ch 6 45
Moving Files and Moving Files and Renaming DirectoriesRenaming Directories
Syntax to rename a directory:
MOVE [/y | /-y] [drive:] [path]
dirname1 dirname2
Ch 6 46
Activity—Moving Files & Activity—Moving Files & Renaming DirectoriesRenaming 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 & Activity—Moving Files & Renaming DirectoriesRenaming 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 RevisitedRD /S Revisited
Two ways to remove a directory: RD (two-step process) RD /S (one-step process)
Ch 6 49
Activity: Using RD Activity: Using RD and RD /Sand RD /S
KEY CONCEPTS: Using RD command Using RD /S command

Backing Up Your Backing Up Your DATA DiskDATA Disk
Always back up all data files.
Backing up application program disks can be tricky, especially copy-protected disks
Ch 6 51
Backing Up Your Backing Up Your DATA DiskDATA Disk
Special operating commands and procedures must be used
to back up a hard disk.
Ch 6 52
Backing Up Your Backing Up Your DATA DiskDATA Disk
Three ways to back up data files: DISKCOPY COPY XCOPY
Ch 6 53
Backing Up Your Backing Up Your DATA DiskDATA Disk
Never use the MOVE command for backup
purposes.
Ch 6 54
Backing Up Your Backing Up Your DATA DiskDATA Disk
Develop a regular backup routine. Can use “tape backup”. Use writable CD if available
Message is BACK UP DATA FILES
Ch 6 55
Backing Up Your Backing Up Your DATA DiskDATA Disk
Application programs can usually be reinstalled from
original disks.

Activity—Backing Up with Activity—Backing Up with the DISKCOPY Commandthe DISKCOPY Command
KEY CONCEPTS: How to not accidentally copy hard
drive Use DISKCOPY - get 2 copies of
DATA disk
Ch 6 57
Activity—Backing Up with Activity—Backing Up with the DISKCOPY Commandthe DISKCOPY Command
Backup 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 58
Backing Up Files with the Backing Up Files with the COPY CommandCOPY Command
DISKCOPY: Backs up entire floppy disk Formats new disk
Ch 6 59
Backing Up Files with the Backing Up Files with the COPY CommandCOPY Command
COPY: Used to backup specific files Copy files from one floppy to another Does not format new disk Must not be used to copy all files from
hard disk to floppy
Ch 6 60
Backing Up Files with the Backing Up Files with the COPY CommandCOPY Command
Do regular backups: Back up files that have changed or
are new
