----------------------- ERASE - Internal DOS Command -------------------------
ERASE removes files from disk on the specified drive in the specified directory.
FORMAT: ERASE [d:][path][filename[.ext]]
REMARKS:
d: - the drive letter of the disk whose files are to be erased. If
omitted, the default drive is assumed.
path - the directory path of the directory whose files are to be erased.
If omitted, the current directory is assumed.
filename - the filename of the file(s) to be erased.
.ext - the filename extension of the file(s) to be erased.
DEL can be used as a short form of ERASE.
If no filename is given, *.* (all files) is assumed.
Global characters (? and *) are allowed in filenames and extensions. Take
care in using these characters since many files can be erased with one ERASE
command.
If you use *.* for the filename to erase all files in a directory or a disk,
DOS will issue the message:
Are you sure(Y/N)
Entering N (and then RETURN) will abort the ERASE command; entering Y
(and then RETURN) will execute the command. This message/prompt warns
you that many files may be erased and gives you a chance to change
your mind.
ERASE will not work for:
Hidden DOS system files.
The "." and ".." files in a subdirectory.
Files marked as read-only (DOS Version 3).
Subdirectories. Use the RMDIR command to remove a subdirectory.
NOTE: The ERASE command does not destroy data. When a file is erased, the
directory entry for the file is altered to indicate that the file is no
longer in use. The disk sectors that contain the file's contents are then
available for reuse. If these sectors have not been reused, it is possible
to retrieve part or all of the erased file. Utility programs that can
restore erased files may be purchased. One such utility program is found in
a package called "The Norton Utilities."
WARNING: Global characters (? and *) are allowed in filenames and extensions.
Take care in using these characters since many files can be erased with one
ERASE command. If no filename is specified, ERASE assumes all files (*.*)
are to be erased.
EXAMPLES:
Erase the file MYFILE in the current directory on the default drive:
ERASE MYFILE
Erase the file MYFILE in current directory on drive B. The default drive is A:
ERASE B:MYFILE
Erase all files in the BUDGET directory on the default drive. BUDGET is a
subdirectory of the root directory:
ERASE \BUDGET
Erase the file MYFILE in the BUDGET directory on the default drive. BUDGET is a
subdirectory of the root directory:
ERASE \BUDGET\MYFILE
Erase all files in the current directory on the default drive:
ERASE *.*
Erase all files in the current directory on the default drive whose filenames
are eight characters long and end in "84." All such files are to be erased
regardless of their filename extensions:
ERASE ??????84.*
