* CMFiler -- Version 5.36 *
* *
*******************************
The following features have been added or improved since the printing of
the CMFiler Version 5.35 User's Manual:
Support for VGA 25/43/50-Line Display:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If your VGA monitor is set up in one of the standard display
configurations, CMFiler will recognize it and permit on-the-fly changes
to 25-, 43- or 50-line display through the Shift-O user Options screen,
last line. The selection is recorded as the default for the next
execution of CMFiler. You can also force your VGA into a specific
display with one of the explicit command line arguments @V25, @V43 or
@V50.
Expanded Support for Laptop Displays:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
There are two classes of laptop computers for which CMFiler has not
previously provided adequate support because of their unconventional
(compared to desktops) displays with respect to the high-intensity bit of
the color attribute. The high-intensity bit is the way a monitor gives
you bright white on blue instead of normal white, for example, or bright
yellow instead of brown. The high-intensity bit is crucial to many of
CMFiler's displays.
The first class of these unconventional laptops, of which some Epsons and
Packard-Bells are members, do not respond to or show little effect of the
high-intensity bit. For this case we have devised an alternative color
attribute set, invoked by E (for Epson, the first of these laptops we
contended with) on the next-to-last lline of the Shift-O user Options
menu, or @E on the command line.
The second class responds in inverted sense to the high-intensity bit,
and it is found in Tandy black-and-white LCDs and some color LCDs. For
this case we have added a switch to the Shift-O Options menu above the
monitor type selection.
If you have a laptop that is not giving you an easily readable display,
try various combinations of color sets and positions of the "high-
intensity inverted" switch. If none of these works, please contact
NoVaSoft with the symptoms.
Choice of Sort Algorithm:
~~~~~~~~~~~~~~~~~~~~~~~~~
The user may pick between "bubblesort" and "quicksort" sorting
algorithms, depending on which proves faster in actual use. The original
bubblesort was replaced with quicksort in Ver 5.35a based on a
theoretical gain in sort time , but quicksort's performance has proved
too variable and is in many cases slower than bubblesort. For this
reason, bubblesort was put back in as an alternative sort method. You
may toggle between the two by pressing A in the Ctrl-O Order mode screen.
Quicksort works particularly well in a large directory where the natural
DOS order is nearly the same as the order in which files are being sorted
by CMFiler. One way to reestablish a particular order to a large
subdirectory is to move all the files. Just create a new directory in
the same level as the directory to be reordered, tag and move all the
files to the new directory, delete the old one and rename the new to the
old name. This has the effect of reconstructing the directory table in
the order in which the files are moved.
New Floppy-filling Function:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A new function has been added to fill target floppies in A or B drive
from a source hard disk directory. Floppies must be already formatted,
but need not be completely empty. The function is "smart", in that it
looks first to see if any files tagged for filling from the source
directory already exist on the floppy, updates them only if needed, and
then adds files as tightly as they will fit, untagging files in the
source as they are successfully copied.
Put the first floppy to be filled in A or B, and set up this drive as the
target. Set up the directory with the files to copy as the source, tag
all the files to be used as "fill", and press Shift-I. CMFiler first
asks how much space you want to reserve for growth on each floppy disk,
and then proceeds with filling the first. After each floppy disk is
filled, you may either keep going or escape. You may even suspend the
operation and, as long as you don't disturb any tags on the source
directory, then resume it where you left off.
New Method of Clearing Slack Space During Copy:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The old method of ensuring no sensitive or classified information was
inadvertently carried into the "slack space" of the last sector written
during file copy operations was to clear the DOS input/output buffers
before writing. The location of this buffer structure varies somewhat
among operating systems. CMFiler's ability to find it in networks was
not fully reliable, and DR DOS reacts very badly to this technique.
The new method for clearing the last-sector slack space is system-
independent, uses standard functions only, and actually results in
shorter file copying times. It is always invoked, and the I/O buffer
clearing switch in the Shift-O menu has been redefined as a "wipe-file"
switch below.
Wipe-File Feature:
~~~~~~~~~~~~~~~~~~
A wipe-file option has been added which causes all of the data in any
file being deleted or overwritten during a copy or move to be completely
obliterated before the DOS file delete service is invoked. It is not a
widely recognized fact that the DOS delete service simply changes the
first character in the filename in the directory listing, and resets the
File Allocation Table entries for the clusters previously used by the
file, but otherwise leaves the clusters containing the actual data alone.
Thus, a disk showing no files may actually have a wealth of data, if one
is smart and patient enough to read each cluster and figure out how they
fit together. This option may be exercised with the switch on line 3 of
the Shift-O user Options menu.
CMFiler -- Errata 1-2
Individual Configuration on Networks:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Different users on a network may specify their own .CFG configuration
file through a parameter passed in the environment. The parameter is
called CF-CFG, and should include the complete file specification. For
example, if C:\PROGRAMS is the network common area for programs, and
CMFiler is in this directory as CF.COM and CF.OVY, and U is a user's
logical drive, and the directory SETTINGS is where that user keeps
miscellaneous program configuration data, the batch file:
SET CF-CFG=U:\SETTINGS\CF.CFG
C:\PROGRAMS\CF
will run CMFiler from the common program area, and tell CMFiler to look
on U:\SETTINGS for CF.CFG. (The file CF.CFG is created if it is not
already there.)
Miscellaneous:
~~~~~~~~~~~~~~
1. The trash can is renamed ~TRASH~ to put it at the end of the
alphabetical directory list.
2. The directory size limit has been increased from 1200 to 2400 files,
if sufficient memory is available. The size limit in the tree mode has
been increased from 505 to 1700 directories.
3. In the editor, the Home and End keys now produce the following
sequential effect: go to beginning/end of line, top/bottom of page,
beginning/end of file.
4. Shift-R (Refresh panel from disk) is added for main module, and
reconfigured from Alt-R in tree.
5. The file lists in ZIP, ARJ, LZH, ARC and EXE self-extracting files
may now be seen just by putting the cursor on the file and pressing
Enter. This facility sees the filenames even when compressed files of
different types are packed into a single file.
6. The file date/time facility is expanded to allow mass date/time
setting of tagged files.
7. CMFiler protects antivirus signature/integrity data files. The
default name assumed for the Stiller Research Integrity Master's
integrity data files is updated to the name ZZ##.IM from )(.ID,
consistent with Integrity Master's default naming convention in version
1.24a and later. It may be changed with the command Alt-I (for "IDname
change").
