It is a helper program needed by the Fat32.ifs file system driver. The program has several functions. It should be started from the config.sys file, but can also be executed from the command line.

CALL=C:\OS2\FS\Fat32\Cachef32.exe Parameter

• /B:value

  This is the amount of time that the cache-buffer had to be idle before the cache data must be written to disk. The OS/2 Online help says that the BUFFERIDLE time must be smaller than the DISKIDLE time. I think this is wrong!
