C:\WINDOWS>HELP FORMAT
Formats a disk for use with Windows XP.

FORMAT volume [/FS:file-system] [/V:label] [/Q] [/A:size] [/C] [/X]
FORMAT volume [/V:label] [/Q] [/F:size]
FORMAT volume [/V:label] [/Q] [/T:tracks /N:sectors]
FORMAT volume [/V:label] [/Q]
FORMAT volume [/Q]

 volume          Specifies the drive letter (followed by a colon),
                 mount point, or volume name.
 /FS:filesystem  Specifies the type of the file system (FAT, FAT32, or NTFS).
 /V:label        Specifies the volume label.
 /Q              Performs a quick format.
 /C              NTFS only: Files created on the new volume will be compressed
                 by default.
 /X              Forces the volume to dismount first if necessary.  All opened
                 handles to the volume would no longer be valid.
 /A:size         Overrides the default allocation unit size. Default settings
                 are strongly recommended for general use.
                 NTFS supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K.
                 FAT supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K,
                 (128K, 256K for sector size > 512 bytes).
                 FAT32 supports 512, 1024, 2048, 4096, 8192, 16K, 32K, 64K,
                 (128K, 256K for sector size > 512 bytes).

                 Note that the FAT and FAT32 files systems impose the
                 following restrictions on the number of clusters on a volume:

                 FAT: Number of clusters <= 65526
                 FAT32: 65526 < Number of clusters < 4177918

                 Format will immediately stop processing if it decides that
                 the above requirements cannot be met using the specified
                 cluster size.

                 NTFS compression is not supported for allocation unit sizes
                 above 4096.

 /F:size         Specifies the size of the floppy disk to format (1.44)
 /T:tracks       Specifies the number of tracks per disk side.
 /N:sectors      Specifies the number of sectors per track.



C:\WINDOWS>HELP FTYPE
Displays or modifies file types used in file extension associations

FTYPE [fileType[=[openCommandString]]]

 fileType  Specifies the file type to examine or change
 openCommandString Specifies the open command to use when launching files
                   of this type.

Type FTYPE without parameters to display the current file types that
have open command strings defined.  FTYPE is invoked with just a file
type, it displays the current open command string for that file type.
Specify nothing for the open command string and the FTYPE command will
delete the open command string for the file type.  Within an open
command string %0 or %1 are substituted with the file name being
launched through the assocation.  %* gets all the parameters and %2
gets the 1st parameter, %3 the second, etc.  %~n gets all the remaining
parameters starting with the nth parameter, where n may be between 2 and 9,
inclusive.  For example:

   ASSOC .pl=PerlScript
   FTYPE PerlScript=perl.exe %1 %*

would allow you to invoke a Perl script as follows:

   script.pl 1 2 3

If you want to eliminate the need to type the extensions, then do the
following:

   set PATHEXT=.pl;%PATHEXT%

and the script could be invoked as follows:

   script 1 2 3



C:\WINDOWS>HELP GOTO
Directs cmd.exe to a labeled line in a batch program.

GOTO label

 label   Specifies a text string used in the batch program as a label.

You type a label on a line by itself, beginning with a colon.

If Command Extensions are enabled GOTO changes as follows:

GOTO command now accepts a target label of :EOF which transfers control
to the end of the current batch script file.  This is an easy way to
exit a batch script file without defining a label.  Type CALL /?  for a
description of extensions to the CALL command that make this feature
useful.
