FASTOPEN(DOS) UNIX System V FASTOPEN(DOS)
Name
fastopen - reduce the time needed to open frequently-used
files
Syntax
fastopen [d:[-nn]]
Description
The fastopen command is an MS-DOS kernel extension that
remembers the locations of files on fixed disks. Whenever
fastopen is installed and a file is to be opened, fastopen
is asked for the location of the file. If the location of
the file is known, fastopen returns the location. The file
can then be opened with greatly reduced disk activity. If
fastopen is not installed, the normal file opening method is
used. Every time a file is opened, fastopen records the name
and location of the file.
The fastopen command only works with local, fixed disks. It
can work with up to four fixed disks at a time. The fastopen
command works with the disks corresponding to the drive
specifications included in its command line arguments. The
fastopen command does not work with remote drives.
By default, the last 10 files opened on each disk are
remembered. As few as 10 and as many as 999 files per disk
can be remembered by using an optional argument along with a
drive specification. As an example, the following line will
cause fastopen to track 100 files on drive C:.
c:=100
Approximately 40 bytes of extra memory is needed to record
information on each additional file.
