- FILES=xx
-
- xx specifies the maximum number of files (from 1 to 99 (pre DOS 3.2) or
- 255 (DOS 3.2 and later)) that the system can have open at any one time.
- The default value is 8. If you specify a number below 5, DOS will
- allow you to open 5 anyway. The most that any one program can have
- open on most versions of DOS is 20.
-
- After a program opens a file, it can then access the contents of the file.
- If you allow too few files to be open, then the program must close one file
- to open another when it needs to access different files. Each open and close
- takes time, so it is quicker to open several files at once and leave them
- open. The default value of 8 is usually too low, a value of 20 or so works
- better. If FILES is set too low, sometimes redirection (<, >, and >>) will
- not work properly.
