=====================UPDATE DOC ============================
************************************************************
** WHAT'S NEW in this latest version of DIET ver1.20 ****
************************************************************
[1] You can compress device drivers!
Devise Drivers compression -D option.
From this version on, you can compress device drivers, too.
Device driver is a file with '.SYS' extensions usually, and
is used with a line 'device?????.sys' in your config.sys
DIET checks whether a file is a device driver by the
leading FF FF block of the file. There are some device driver
without this block. You have to use -I option together with
-D option.
This is a good news for the people in countries where you
need extra display.sys and code switching tables.
[2] You can COPY dieted files COMPRESSED or DECOMPRESSING!
Copy DIETED files may cause extra time. COMMAND.COM will
decompress the file and then copy to the directory; then TSR DIET
will recompress the file again. You can use -C option to copy files
as compressed as they are. If DIET finds newer file(s) with same
name(s), then DIET will skip the files(s).
When you store compressed files of Floppy disks, and use them
on a RAMDISK, you may use this method to restore files compressed.
<Example 1.> To copy all the files on the current directory c:\
to Floppy Disk A:
DIET -CA:\ C:\*.*
~~~~~~~~~~~~~~~~~~~
When you keep files compressed on floppies and use them on a RAMDISK
in decompressed shape. You may copy file(s) with resotoring to the
original size(s).
<Example 2.> To copy compressed files on Floppy disk in drive A:,
to a RAMDRIVE C:\ in the original size for faster execution.
DIET -RA -CC:\ A:\*.*
[3] REMOVE or KILL temporary files when you wish!
Kill temporary Files when you quit, with -K option.
Resident part of DIET opens a temporary file whenever a
compressed file is opened in read-mode. The temporary file
is erased whenever the program closes the file. However,
there are programs which open and close a file frequently,
e.g. a Help Message file, creating and erasing temporarily.
This type of file is very much time consuming for TSR DIET.
The option -K should be used when you compress a file with
DIET. This is a new option, from this version DIET ver.1.20.
You must remember you need a fairy large amount of space for
your temporary file. The temporary file is erased when
the program terminates.
You can check whether your file is compressed with -K option
or not with -H option.
[4] New Display for -L option.
DIET -L --------- list dieted and undieted files!
In the following list, filenames headed with an asterisk *, show
their names in reverse color.
*TAIL.EXE *UUDECODE.EXE *UUENCODE.EXE *EMACS.EXE EMACS.HLP
*BDIFF.EXE BDIFF.DOC *BUPDATE.EXE *CSH.COM LHA.EXE
*LOG.EXE SETUPE.EXE CFREQ.EXE REV.EXE SORT.MAN
You will know how much of your files are compressed with DIET
by this display. Visual and helpful.
