<P>The number of directory entries is not always the same as the number of\
   files which can be saved when large files are used, because every 16K\
   requires an extra directory space.\
<P>The maximum number of files which can be CATed is 140, although any\
   number of files can be DIRed.  This is because the buffer for CATing is\
   only 2K long and although this could be enlarged it could cause\
   compatibility problems with other software.  Therefore it is best to\
   allocate different types of files to different User groups when a large\
   number of files are kept on a disc.  This should also make the disc more\
   organised and easier to use.\
