- FASTOPEN
- Store location of recently used files for faster access
- See also <CONFIG.SYS> <INSTALL>
-
- COMMAND TYPE: External VERSION: 3.3 and up
-
- DOS locates files by searching each directory in the path each time the
- file is accessed. On fixed disks with complex directory structures, this
- can take a large amount of time. FASTOPEN stores in memory the location of
- directories and recently opened files, and searches this list first when
- opening a file. It is most useful for applications which open and close
- many files.
-
- USE: FASTOPEN [d:[=n][ ... ] [/X]
- or FASTOPEN [d:[=([n],m)][ ... ] [/X]
-
- d: to specify the drive to process. Any fixed disk drive may be used.
- n the number of directories or file entries to remember for the drive
- given as "d". The default is 10. (Range is 10-999.)
- m is the number of file extent entries for the drive named (DOS 4.x only)
- If not present, the feature is not provided.
- /X indicates the the FASTOPEN cache should be placed in expanded (LIM 4.0)
- memory (DOS 4.x only)
-
- Fastopen works only on fixed discs (up to 4) and will not work with networks.
-
- FASTOPEN can be used only once. All drives must be defined the first
- time FASTOPEN is used.
- (DOS 4.x)
- FASTOPEN may be executed at boot time using INSTALL in <CONFIG.SYS>
