cd A: to A disk root directory of the current directory to
cd A: xx A disk will change the current directory, a subdirectory under the
cd xx .. 98 to return to the parent directory, and then to the parent directory of the 98 sub-
cd .. back to the parent directory
cd 98 into the root directory of the 98 sub-
Fourth, copy [/ y] [/-y] [/ v] [/ B]
copy / y without prompt to overwrite all files
/-y to be prompt for all files (yes or no questions)
/ v to copy after checking
/ B for display by the binary
copy w1.wps con / b wps files can be displayed on the screen without having to enter the state

xcopy [/ p] prompted to create a subdirectory
xcopy [/ s] associated with the copy of the directory. Note: If the destination disk This directory does not exist, and in the target disk terminator
not to [f = file, d = directory]?
create a file on the target disk [Press] or create a subdirectory [press d]? should choose the d key
xcopy [/ v] with more experience
*: (1) xcopy does not copy system and hidden file attributes should be modified re-copy
xcopy [/ y] if there was coverage prompted, / y omitted without target disk if prompted
or sub- directory name, then copied to the current directory
June, del / p
add / p to whether to prompt before removal, such as del
added subdirectory name, all the files in the subdirectories (implied. system. except for read-only file) Full deleted,
plus / p, you can confirm.
seven, undelete [name] / au
without prompt to meet the conditions of all the file recovery (to recover), and set the first letter a -9 a-z / list recoverable file list only, and not restore
undelete / load into memory will undelete
/ unload unloading will undelete memory
/ s [drive] drive for the specified monitoring and management
undelete / sc
will undelete resident memory? and creates a hidden subdirectory on the c drive sentry deleted files
management undelete / ds
corresponding recovery restore undelete command can be used to complete to recover the file name (very complete)
most common undelete *.*
deltree / y [drive: path]
deltree to delete subdirectories and files, although some files are system files or hidden files
it with a wildcard, with a wildcard, it will delete files and subdirectories eligible
such as:? undelete *. dbf / au to the extension and the unload unloading the undelete memory.
/ s [drive] on the specified drive monitoring management.
undelete / sc to undelete memory-resident, and create a hidden directory on the C drive sentry deleted
The file management. accordingly the recovery command can undelete / ds to recover the full file name (very sound).
most commonly used is undelete *.*
eight , deltree / y [drive: path]
deltree to delete subdirectories and files, although some files are system or implied.
it with a wildcard, then it will delete files or eligible subdirectory.
such as: file exists L1,
mulberry handbags, L2 directory, L3 files, L4 subdirectory
deltree L *.* will delete all of the above files and subdirectories, but to confirm before deleting, if not removed,
can enter file, you can use special
special tools. such as NORTON 8.0.
if early use of undelete / s,? can be found in the sentry complete file directory, but the name has
changed.
nine, dos = high [| low [umb | noumb]]
dos = high, umb the dos itself into high memory (high) and can manage the upper memory (umb).
noumb not manage upper memory.
dos = high, and in writing before umb device = himem.sys
to load programs or drivers into the upper memory, you must use dos = umb, can save the majority of conventional memory.
can write anywhere config.sys dos = high, umb
If the display hma not avoiable or load down low is that you can not use high-end memory.
ten, doskey struck the previous record dos command, you can use F7 to show, using .
doskey / restall reload time, the previous undo command.
doskey / history shows all the commands in memory, you can .
doskey dir = cls is hit into the same dir the same as cls.
doskey / macros to display all of the macro definition, use the ;.
doskey dir = dir can be undone on the macro definition.
doskey p = dir $ tdir *. exe / p $ tdir c: t $ tdir c: t $ *
$ t for the the distinction between the command characters, and $ * for the command terminator
doskey / insert (overstrike)? re-enter the command, change the old order is to insert or cover
cover state (default).
XI, emm386.exe
provide extended memory management, so as to use the application to use it as conventional memory.
common usage is in the config.sys in the
device = c: dos himem.sys
device = c: dos emm386.exe ram
d = 64 the number of DMA memory is set to 64K
noems provide access to upper memory, but does not provide access to extended memory.
should be noted that the best in the windows do not use it, because windows itself
the extended memory management procedures. should be used in the windows manager.
second, fc command fc / b dt.dat dt2.dat> b (for binary code comparison)
compare two files, generally used for access to the progress,
designer handbags, changes game store file with the.
0100 should be added to the actual code location, such as: 0000 05E4: 00 67
actual changes with the debug-e 0100 should be added that 0000 06E4: 00 67
followed by the redirection file ;> P : a quick format, only scan the file allocation table and root directory area, only the effective disk formatted.
use should ensure that the format did not increase after the new bad sectors.
/ u parameter: unconditional format of, and does not save the information on the original disk, you can prevent the 160 180 320 360 720 1200 1440 2800
/ n: sector n the format for a single-sided disc with a capacity of 160k 180k
for 4 to 5 inch high density drive can be formatted 360k disks
8-inch high density in the 5 to 8 on the drive sector format.
/ c re-test bad sectors, by default if a sector is marked as test
test, only for tags, use the and did not use the ,],[continue.
/ test only for a test, not for the actual repair work, for the simulation.
/ p side of the test side of the print.
Note: This method does not guarantee repair all the files, in particular format then add the data of the disk over.
restore order after the file stored in the subdir1 .... 2 .... 3 and other subdirectories.
XV interlnk syntax interlnk g = e, it can be serial or parallel communication between the two machines.
e on the server-side drive mapping for the client of the g drive, after the client, all of g's
operations means that access to the server, cancel mapping approach for the interlnk g =
separate input interlnk shows the mapping of all cases.
Note: interlnk interlnk.exe must load the device driver can use .
drive used symbols and config.? sys related to the number set in the lastdrv.exe. You can make a 25-pin end of a
the other end a 9-pin serial cable to achieve the specific connection as follows:
5 - 7 2 - 15
3 - 2 3 - 13
7 - 4 4 - 12
6 - 6 5 - 10
3 - 3 6 - 11

25 - 25
25-pin 25-pin
sixteen,
gucci handbags, interlnk.exe and intersvr.exe
interlnk.exe redirected drive or print for the customer interface, the request to another server, or printer driver
.
syntax: config.sys add:
device = c: dos interlnk.exe [drive: n] [/ noprinter] [com] [lpt]
ten VII, memmaker [/ batch] [session] [/ swap: drive]
to optimize memory use memmaker configuration? and write autoexec.bat and config.sys in the configuration.
in the process, several times to restart the machine.
eighth, memitem memcolor memdefault submenu in the menu options include
autoexec.bat as follows: config.sys the following:
path c: dos; c: ucdos [menu]
doskey menucolor = 15,1 (15, foreground color, background color, 1)
mouse mouse menuitem = base_config, this is a base
goto% config% -> select the item menuitem = cced_config, this is a cced
option prompts
: base_config menudefault = base_config, 5
goto exit -> out of default base_config, delay time 5 seconds
: cced_config [common]
c: dos smartdrv.exe / l device = c: dos himem.sys
goto exit contains the common parts of the
: exit - > end [base_config]
device = c: dos emm386.exe ram
dos = high, umb
[cced_config]
device = c: dos smartdrv.exe / double_buffer
include = base_config
can contain base_config set in the computer configuration requirements under different conditions to choose.
nineteenth, mscdex.exe drive to provide literacy program
mscdex / d: drive [/ D: drive] [/ e] [/ k] [/ s] [/ l: letter]
typical: config.sys in the device = c: cdrom cdrom.sys / d: mscd000
autoexec.bat in the c: dos mscdex / d: mscd000 / l: g
equipped with an optical drive, symbol g
parameter / d: drive1 as CD-ROM drive identification number, to be consistent with the symbols in config.sys can have multiple
/ d: mscd000 / d: mscd001
/ e: drive using the extended memory to load the driver.
/ s: to drive the ms_net or windows is set to share the drive
/ V is displayed when loading the memory.
/ L: letter assigned to the CD-ROM drive
/ m: number Specifies the number of buffers
It should be noted:? If smartdrv.exe accelerate the literacy drive, should autoexec.
bat will mscdex.? exe prior written smartdrv.exe, smartdrv.exe can significantly increase the use of
on literacy drive.
twenty, msd msd can use
use of the overall configuration and check the computer system information
include:? drive parameters parameters of the computer cpu, memory size parameters,
miu miu handbags, display type, string. parallel port, so as to
and occupancy of each IRQ, thus can analyze the new equipment is in conflict with the original equipment.
can also analyze the memory in to stay proceedings to determine whether the virus in memory, there are marked $ t equals the current date current time $ d $ p Current drive symbol
$ $ $ number prompt $ n is greater than the current drive number $ g $ b $ l less-than display $ E $ h withheld prompt display in number.
twenty-two, ramdrive.sys using memory as a virtual disk to use
should be noted that all data in memory, it is timely to save to your hard drive, or power-down or crash
will be lost after all the data, the advantage of running speed, but can not be used in windows.
Example: config.sys: device = c: dos ramdrive . sys / size [/ e | a]
size as the number of bytes in units of k, namely the establishment of the virtual disk size.
/ e or / a is to use extended memory to create a virtual disk, ? add parameters on the premise that you must load the device memory management
himem.sys and emm386.exe.
twenty-three, subst a drive with a child directory junctions
such as: will A: l1 l2 subdirectory disk request is mapped to S, then enter
subst s: a: l1 l2 to
such use dir s:?, etc. command shows that the a: l1 l2 subdirectory, any other copy del can be used as
subst s: d to cancel this mapping.
subst can be used to display various connection conditions
Note:? can subst a: c: a to create a reading and writing for the A disk.
install the software for some, it? must use the A drive to install, you can use the software to be installed first All copy to C: a sub-
directory, then enter the subst a: c: a, then go to A:, the software can be installed.
twenty Fourth,
tory burch handbags, mem / c / m / p / d of conventional memory display program
/ c show all the occupancy of the memory-resident programs, conventional memory into conventional memory footprint and uppermemory
high and show the total occupation conditions (conventional high-end extended memory retention)
/ p page display, page temporarily
/ m, add the module name, such as: / m msdos dos system memory usage display.
/ d of conventional high side to be more cases of extended memory retention table shows
the analysis, we can see that the memory footprint is reasonable, and various procedures is normal load, resulting in the use of this base
basis for a variety of memory management optimization tools memmaker while some programs can analyze the causes crash
, if the local display memory
twenty-five ,>>due to the required input or output redirection
as: dir *. bat / b> p case can be dir *. bat file name output to a file in the p.

twenty VI, move command
move [y /-y] filename1 filename2
move the file to a file 2 1
such as: move c: dos *.* c: cced
to dos all files under all subdirectories to move to the cced subdirectory
/ y |-y parameter in the target directory does not exist need to create,
paul smith bags, whether prompted
can use this command to modify subdirectory name, such as the move dos cced
dos directory name will be changed to cced
twenty-seven, append some special data file specified storage location, such as user.dat pe2.pro and some non-*.
exe *. com *. bat file
Format: append [:] to terminate the pre-existing conditions specified directory append Displays
append [path] append c: user, etc.
twenty-eight,
call in a batch command to call another batch file
