FASTOPEN + Storing Recently Opened Files in Memory
     Stores in memory the location of directories and recently 
opened files so that files can be located quickly.
    VERSION
          PC-DOS 3.3 
    TYPE
          External 
    SYNTAX
	  [d:][path] FASTOPEN pd:[=nnn]
    OPTIONS
	  [d:][path]	 Specifies the drive letter and path that
                         contain the FASTOPEN command file.
	  pd:		 Specifies the drive to process.
	  [=nnn]	 Specifies the number of directories or
                         files to remember for the drive 
			 specified as pd:. If no number is
                         specified, the default of 34 is used. 
                         The range of numbers specified must be 
                         between 10 and 999. In addition, the sum 
			 of all nnn files cannot exceed 999.
     FASTOPEN is used to speed up access of files on hard disks 
with complex directory structures.
    EXAMPLE
	  FASTOPEN C:100
instructs DOS to remember the locations of the last 100 
directories or files that were opened on drive C.  
    MESSAGES
	  Cannot use FASTOPEN for drive x
FASTOPEN can be used only on hard disk drives. It cannot be used 
on floppy drives or on network drives, or on drives that have 
been operated on with the JOIN, SUBST, or ASSIGN command.
	  FASTOPEN already installed
FASTOPEN has already been loaded. No action is required.
	  Same drive specified more than once
Reenter the command, specifying each drive letter once.
	  Too many drive entries
You have specified too many drive letters. Reenter the command 
with fewer drive letters.
	  Too many name entries
You have specified a number greater than 999. Change the number 
to less than 999 and try again.
    NOTES
     FASTOPEN is used only once, and it is usually placed in the 
AUTOEXEC.BAT file.
     The minimum number of directories or file entries that 
FASTOPEN remembers the location of is 10; the maximum is 999. The 
number you assign should be greater than the deepest level of 
subdirectory you are using. If you access more than the number of 
files you specified during a session, the least recently accessed 
file is removed from the list and replaced by the most recently 
accessed file.
