format<\/strong> Volume<\/em> [\/s<\/strong>]<\/p>\n

Parameters<\/h2>\n

Volume<\/em><\/p>\n

Specifies the mount point, volume name, or drive letter (followed by a colon), of the drive you want to format. If you do not specify any of the following command-line options, format<\/strong> uses the volume type to determine the default format for the disk.<\/p>\n

\/fs:<\/strong>FileSystem<\/em><\/p>\n

Specifies the file system to use file allocation table (FAT)<\/a>, FAT32<\/a>, or NTFS<\/a>. Floppy disks can use only the FAT file system.<\/p>\n

\/v:<\/strong>Label<\/em><\/p>\n

Specifies the volume label. If you omit the \/v <\/strong>command-line option or use it without specifying a volume label, format<\/strong> prompts you for the volume label after the formatting is completed. Use the syntax \/v:<\/strong> to prevent the prompt for a volume label. If you format more than one disk by using one format<\/strong> command, all of the disks will be given the same volume label. For more information about disk volume labels, see Related Topics.<\/p>\n

\/a:<\/strong>UnitSize<\/em><\/p>\n

Specifies the allocation unit size to use on FAT, FAT32, or NTFS volumes. If you do not specify UnitSize<\/em>, it is chosen based on volume size. The following table lists valid values for UnitSize<\/em>.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n
Value<\/strong><\/td>\nDescription<\/strong><\/td>\n<\/tr>\n
512<\/strong><\/td>\nCreates 512 bytes per cluster.<\/td>\n<\/tr>\n
1024<\/strong><\/td>\nCreates 1024 bytes per cluster.<\/td>\n<\/tr>\n
2048<\/strong><\/td>\nCreates 2048 bytes per cluster.<\/td>\n<\/tr>\n
4096<\/strong><\/td>\nCreates 4096 bytes per cluster.<\/td>\n<\/tr>\n
8192<\/strong><\/td>\nCreates 8192 bytes per cluster.<\/td>\n<\/tr>\n
16K<\/strong><\/td>\nCreates 16 kilobytes per cluster.<\/td>\n<\/tr>\n
32K<\/strong><\/td>\nCreates 32 kilobytes per cluster.<\/td>\n<\/tr>\n
64K<\/strong><\/td>\nCreates 64 kilobytes per cluster.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

\/q<\/strong><\/p>\n

Performs a quick format. Deletes the file table and the root directory of a previously formatted volume but does not perform a sector by sector scan for bad areas. You should use the \/q<\/strong> command-line option to format only previously formatted volumes that you know are in good condition.<\/p>\n

\/f:<\/strong>Size<\/em><\/p>\n

Specifies the size of the floppy disk to format. When possible, use this command-line option instead of the \/t<\/strong> and \/n<\/strong> command-line options. Windows accepts the following value for size:<\/p>\n

1440 <\/strong>or 1440k <\/strong>or 1440kb <\/strong>or 1.44 <\/strong>or 1.44m <\/strong>or 1.44mb <\/strong>
\n1.44-MB, double-sided, quadruple-density, 3.5-inch disk<\/p>\n

\/t:<\/strong>Tracks<\/em><\/p>\n

Specifies the number of tracks on the disk. When possible, use the \/f<\/strong> command-line option instead of this command-line option. If you use the \/t<\/strong> command-line option, you must also use the \/n<\/strong> command-line option. These two command-line options provide an alternative method of specifying the size of the disk being formatted. You cannot use the \/f<\/strong> command-line option with the \/t<\/strong> command-line option.<\/p>\n

\/n:<\/strong>Sectors<\/em><\/p>\n

Specifies the number of sectors per track. When possible, use the \/f<\/strong> command-line option instead of this command-line option. If you use the \/n<\/strong> command-line option, you must also use the \/t<\/strong> command-line option. These two command-line options provide an alternative method of specifying the size of the disk being formatted. You cannot use the \/f<\/strong> command-line option with the \/n<\/strong> command-line option.<\/p>\n

\/c<\/strong><\/p>\n

NTFS only. Files created on the new volume will be compressed by default.<\/p>\n

\/x<\/strong><\/p>\n

Causes the volume to dismount, if necessary, before it is formatted. Any open handles to the volume will no longer be valid.<\/p>\n

\/s<\/p>\n

Copies system files to the formatted disk. (Windows 9x only)<\/p>\n

MD\/CD\/RD<\/h1>\n

Mkdir (MD)<\/h1>\n

Creates a directory or subdirectory.<\/p>\n

Syntax<\/h2>\n

mkdir<\/strong> [Drive<\/em>:<\/strong>]Path<\/em><\/p>\n

md<\/strong> [Drive<\/em>:<\/strong>]Path<\/em><\/p>\n

Parameters<\/h2>\n

Drive<\/em>:<\/strong><\/p>\n

Specifies the drive on which you want to create the new directory.<\/p>\n

Path<\/em><\/p>\n

Required. Specifies the name and location of the new directory. The maximum length of any single path is determined by the file system.<\/p>\n

\/?<\/strong><\/p>\n

Displays help at the command prompt.<\/p>\n

Displays the name of or changes the current directory.<\/p>\n

CHDIR (CD)<\/h1>\n

CHDIR [\/D] [drive:][path]<\/p>\n

CHDIR [..]<\/p>\n

CD [\/D] [drive:][path]<\/p>\n

CD [..]<\/p>\n

..\u00a0\u00a0 Specifies that you want to change to the parent directory.<\/p>\n

Type CD drive: to display the current directory in the specified drive.<\/p>\n

Type CD without parameters to display the current drive and directory.<\/p>\n

Use the \/D switch to change current drive in addition to changing current<\/p>\n

directory for a drive.<\/p>\n

If Command Extensions are enabled CHDIR changes as follows:<\/p>\n

The current directory string is converted to use the same case as<\/p>\n

the on disk names.\u00a0 So CD C:\\TEMP would actually set the current<\/p>\n

directory to C:\\Temp if that is the case on disk.<\/p>\n

CHDIR command does not treat spaces as delimiters, so it is possible to<\/p>\n

CD into a subdirectory name that contains a space without surrounding<\/p>\n

the name with quotes.\u00a0 For example:<\/p>\n

cd \\winnt\\profiles\\username\\programs\\start menu<\/p>\n

is the same as:<\/p>\n

cd “\\winnt\\profiles\\username\\programs\\start menu”<\/p>\n

which is what you would have to type if extensions were disabled.<\/p>\n

Rmdir (rd)<\/h1>\n

Removes (that is, deletes) a directory.<\/p>\n

Syntax<\/h2>\n

rmdir <\/strong>[Drive<\/em>:<\/strong>]Path<\/em> [\/s<\/strong>] [\/q<\/strong>]<\/p>\n

rd <\/strong>[Drive<\/em>:<\/strong>]Path<\/em> [\/s<\/strong>] [\/q<\/strong>]<\/p>\n

Parameters<\/h2>\n

[Drive<\/em>:<\/strong>]Path<\/em><\/p>\n

Specifies the location and name of the directory that you want to delete.<\/p>\n

\/s<\/strong><\/p>\n

Removes the specified directory and all subdirectories including any files. Use \/s<\/strong> to remove a tree.<\/p>\n

\/q<\/strong><\/p>\n

Runs rmdir<\/strong> in quiet mode. Deletes directories without confirmation.<\/p>\n

\/?<\/strong><\/p>\n

Displays help at the command prompt.<\/p>\n

\/CLASSIFY or \/C\u00a0 Classifies programs by memory usage. Lists the size of<\/p>\n

programs, provides a summary of memory in use, and lists<\/p>\n

largest memory block available.<\/p>\n

Ping<\/h1>\n

Verifies IP-level connectivity to another TCP\/IP computer by sending Internet Control Message Protocol (ICMP) Echo Request messages. The receipt of corresponding Echo Reply messages are displayed, along with round-trip times. Ping is the primary TCP\/IP command used to troubleshoot connectivity, reachability, and name resolution. Used without parameters, ping<\/strong> displays help.<\/p>\n

Syntax<\/h2>\n

ping<\/strong> [-t<\/strong>] [-a<\/strong>] [-n<\/strong> Count<\/em>] [-l <\/strong>Size<\/em>] [-f<\/strong>] [-i<\/strong> TTL<\/em>] [-v<\/strong> TOS<\/em>] [-r<\/strong> Count<\/em>] [-s<\/strong> Count<\/em>] [{-j<\/strong> HostList<\/em> | -k <\/strong>HostList<\/em>}] [-w<\/strong> Timeout<\/em>] [-R<\/strong>] [-S SrcAddr<\/em><\/strong>] [-4<\/strong>] [-6<\/strong>] TargetName<\/em><\/p>\n

Parameters<\/h2>\n

-t<\/strong><\/p>\n

Specifies that ping continue sending Echo Request messages to the destination until interrupted. To interrupt and display statistics, press CTRL+BREAK. To interrupt and quit ping, press CTRL+C.<\/p>\n

-a<\/strong><\/p>\n

Specifies that reverse name resolution is performed on the destination IP address. If this is successful, ping displays the corresponding host name.<\/p>\n

-n<\/strong> Count<\/em><\/p>\n

Specifies the number of Echo Request messages sent. The default is 4.<\/p>\n

-l <\/strong>Size<\/em><\/p>\n

The Echo Request message cannot be fragmented by routers in the path to the destination. This parameter is useful for troubleshooting path Maximum Transmission Unit (PMTU) problems.<\/p>\n

-i <\/strong>TTL<\/em><\/p>\n

Specifies the value of the TTL field in the IP header for Echo Request messages sent. The default is the default TTL value for the host. The maximum TTL<\/em> is 255.<\/p>\n

-v<\/strong> TOS<\/em><\/p>\n

Specifies the value of the Type of Service (TOS) field in the IP header for Echo Request messages sent (available on IPv4 only). The default is 0. TOS<\/em> is specified as a decimal value from 0 through 255.<\/p>\n

-r<\/strong> Count<\/em><\/p>\n

Specifies that the Record Route option in the IP header is used to record the path taken by the Echo Request message and corresponding Echo Reply message (available on IPv4 only). Each hop in the path uses an entry in the Record Route option. If possible, specify a Count<\/em> that is equal to or greater than the number of hops between the source and destination. The Count<\/em> must be a minimum of 1 and a maximum of 9.<\/p>\n

-s<\/strong> Count<\/em><\/p>\n

Specifies that the Internet Timestamp option in the IP header is used to record the time of arrival for the Echo Request message and corresponding Echo Reply message for each hop. The Count<\/em> must be a minimum of 1 and a maximum of 4. This is required for link-local destination addresses.<\/p>\n

-j<\/strong> HostList<\/em><\/p>\n

Specifies that the Echo Request messages use the Loose Source Route option in the IP header with the set of intermediate destinations specified in HostList<\/em> (available on IPv4 only). With loose source routing, successive intermediate destinations can be separated by one or multiple routers. The maximum number of addresses or names in the host list is 9. The host list is a series of IP addresses (in dotted decimal notation) separated by spaces.<\/p>\n

-k<\/strong> HostList<\/em><\/p>\n

Specifies that the Echo Request messages use the Strict Source Route option in the IP header with the set of intermediate destinations specified in HostList<\/em> (available on IPv4 only). With strict source routing, the next intermediate destination must be directly reachable (it must be a neighbor on an interface of the router). The maximum number of addresses or names in the host list is 9. The host list is a series of IP addresses (in dotted decimal notation) separated by spaces.<\/p>\n

-w<\/strong> Timeout<\/em><\/p>\n

Specifies the amount of time, in milliseconds, to wait for the Echo Reply message that corresponds to a given Echo Request message to be received. If the Echo Reply message is not received within the time-out, the “Request timed out” error message is displayed. The default time-out is 4000 (4 seconds).<\/p>\n

-R<\/strong><\/p>\n

Specifies that the round-trip path is traced (available on IPv6 only).<\/p>\n

-S<\/strong> SrcAddr<\/em><\/p>\n
