Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

                                  FASTOPEN
 
Starts the Fastopen program, which improves performance on computers with
large directories. Fastopen decreases the amount of time that MS-DOS takes
to open frequently used files. Do not use this command when Windows is
running.
 
Fastopen tracks the location of files on a hard disk and stores the
information in memory for fast access.
 
Syntax
 
    FASTOPEN drive:[[=]n] [drive:[[n][...]] [/X]
 
In your CONFIG.SYS file, use the following syntax:
 
    INSTALL=[[dos-drive:]dos-path]FASTOPEN.EXE drive:[[=]n]
    [drive:[[=]n][...]] [/X]
 
Warning:  To avoid losing data, do not run a defragmentation program such as
          Microsoft Defragmenter while FASTOPEN.EXE is loaded.
 
Parameters
 
[dos-drive:]dos-path
    Specifies the location of FASTOPEN.EXE.
 
drive:
    Specifies a hard disk drive for which you want Fastopen to track the
    opening of files.
 
n
    Specifies the number of files Fastopen can work with at the same time.
    Valid values for n are in the range 10 through 999. The default value is
    48.
 
Switch
 
/X
    Creates the name cache in expanded memory instead of in conventional
    memory. The name cache is an area of memory in which MS-DOS stores
    (caches) the locations and names of the files that you open. This cache
    conforms to version 4.0 of the Lotus/Intel/Microsoft Expanded Memory
    Specification (LIM EMS).
