Executable Program and Documentation
Copyright (C)1990,1991 by Michael Rice



Giflog is a simple, easy to use program to help you manage your
GIF picture file collection. If you are anything like me,
collecting these GIF files has gotten a bit out of hand. At the
this time I have about 125 1.2Mb disks with GIF files on them.
Most of the files sit in one of my floppy boxes and never get
looked at. This can cause quite a problem for the collector. If
I obtain a GIF today how can I remember if I already have it or
not? I certainly don't want to keep multiple copies of the same
file. Giflog helps with this in quite a number of ways. First,
it has a built in CRC (Cyclic Redundancy Check) algorithm that
will help you spot duplicate files. Secondly, it lets you add
comments for each file while cataloging so you can remember what
is in that file at a later date. Thirdly, it has report printing
features to let you know the details of each file such as
filesize, resolution, name, and comment. There are other nifty
little features that make it a nice program to have around. I
hope you'll give it a try. What do you have to lose?


Giflog will create the file GIFLOG.CAT as a default. So the
first time you run Giflog, GIFLOG.CAT will be the name of your
catalog file. You may change this by going to the FILE menu LOAD
option and loading in the filename you desire. You may only load
a filename. Do NOT try to use a full pathname in the LOAD
option. To make this your default go to the OPTIONS menu SAVE

Giflog will also look for the file GIFLOG.CFG. It contains the
Options settings. If this file does not exist, it will use the
default values.

Giflog will always look in two places for GIFLOG.CFG and your
catalog files (normally GIFLOG.CAT). It will first check your
environment for the variable GIFLOG. If this exists it will look
in the directory assigned to the GIFLOG variable. If it doesn't
exist it will look in the directory from which you ran
GIFLOG.EXE. You need to setup in one of the following ways:

1) In your AUTOEXEC.BAT file add the following line:


Where "\GIFLOG\PATH" is the directory you want GIFLOG.CAT and
GIFLOG.CFG to be kept. Don't forget the trailing "\" as it is


essential. After this is done you need to also put GIFLOG.EXE in
a directory that is in your PATH or set your PATH to include
GIFLOG.EXE. You now can run Giflog from any directory in your

2) You may also put GIFLOG.EXE into a directory and specifically
change to that directory before running Giflog. If this is done
GIFLOG.CAT, GIFLOG.CFG, and GIFLOG.EXE will all be in the same
directory. You can put the needed commands into a batch file
(We'll say GIFLOG.BAT) and put this batch file somewhere in your
PATH. You can then run Giflog by typing GIFLOG at any prompt.
With the help of the PUSHDIR and POPDIR utility you can even
return to the directory you started in. Below is a sample batch
file, that I have included with Giflog:


Basic Features:

Giflog is a set of procedures run from an easy-to-use pulldown
menu. The menu options may be selected by either the mouse, the
keyboard, or a combination of both. In general, the left mouse
button will select an option and the right button will remove a
menu. When using the mouse you must unselect a menu with the
right button before moving to another menu. You may remove the
mouse cursor by pressing Alt-M. With the keyboard, you move with
the cursor keys, select with the RETURN key, and unselect with
the ESCAPE key. You may also select an option by pressing the
letter that is highlighted in red. You may hit F1 at any point
to get a brief help message. These aren't meant to be
comprehensive, but may be of some use to those who are a bit

The program was written in C with the Turbo C++ compiler. The
menuing features are from TCU v3.1a (Turbo C Utilities) by Karl
Keyte. I highly recommend this!

File Menu Options:

*Save Catalog:
This saves the current catalog including any new changes made
since the last save. The old catalog is backed up in the file


*Load Catalog:
This loads a catalog file from disk. You can use this to load
GIFLOG.BUP if you just made a mistake, or if you are using
multiple catalog files you can use this to load them. If you
have made changes to the current catalog it will ask you if you
want to save first.

*Add Comments:
This allows you to add comments to a specified volume. You can
also add comments by setting the auto-commenting feature on.

*Activate Viewer:
This will try to activate a GIF file viewer. You must have the
pathname/filename and command line options of the viewer set from
the OPTIONS menu. The default is CSHOW.EXE. It is assumed that
CSHOW.EXE is somewhere in your PATH since the full pathname is
not specified. You must also have enough free memory to do this.
This shouldn't be a problem unless you have a huge catalog file.
Some viewers, such as CSHOW, VUIMG, and VPIC, work well with this

*Delete File:
This option allows you to remove only one file from a volume. It
is useful when you find a duplicate file in your catalog. It
asks for a volume and a file and deletes it if the file is in the
catalog. It also updates volume and file information. Use this
when you only want to remove a few files from the catalog, and
the Uncatalog function when you want to remove the whole volume.

*About GIFLOG:
This will display a screen full of information about GIFLOG, such
as where I can be reached, and a few restrictions.

Catalog Menu Options:

This is the heart of the Giflog program. This option will add
GIF files to the database. There are two ways in which
cataloging can work. The first is designed to work mainly on
floppy disks. Giflog will find all the GIFS in the root
directory of a disk, associate them with the disk's volume label,
and store them in the database. All disks cataloged in this way
must have a volume label. If it does not have one, you will be
given the chance to add it. You can set the drive to catalog
from, in the OPTIONS menu. If the files are already in the
catalog it notifies you and adds the files that are new. If the


auto-commenting option is set on, you will then be given a chance
to update or create comments for each file.

Giflog does not check to see that you have a unique volume label.
All disks labelled the same are thought of as one volume. I
suggest using a labelling method that makes duplicates easy to
spot, and makes disks easy to find. I use the label "GIFS xxx"
where xxx is a number which counts up with each new disk.

The other option you have for cataloging is from a subdirectory.
This is useful if you have a small collection which you keep on
your hard drive, or if keep some on floppies and some in
subdirectories. To use this you must set the option in the
OPTIONS menu CATALOG DRIVE option. With this option set, Giflog
will ask you for the full pathname of the subdirectory you want
to catalog. A full pathname starting with a "\" is required.
You may also specify the drive in the pathname, but it will
default to the drive set in the CATALOG DRIVE option. Giflog
will use the innermost directory as the volume. For example in
the path C:\TEMP\GIFS\BIGCOLOR, the volume would be BIGCOLOR.
The same rules apply for volumes with both ways of cataloging.

This will remove a volume from the catalog. This is a drastic
step. It will erase all information including comments. All
information, except comments, can be scanned back in quickly and
automatically; but comments must be re-entered manually. You may
want to uncatalog a disk if you find a duplicate on it using the
SEARCH DUPLICATES option. If you find a duplicate make a note of
it and use the DELETE FILE option. Since this is such a drastic
step, you will be asked to confirm your choice.

Search Menu Options:

This checks through the whole catalog and compares the CRC value
of each file with every other file. If two files have a matching
CRC value, there is a good chance that the files are the same.
These files are reported, so you can delete them if needed. The
CRC calculated is a CRC of only a limited number of bytes of the
file. This allows much faster cataloging and eliminates CRCs
that are different because of a few stray bytes at the end of the
file. I have over 1300 files cataloged and don't have any false
reports at this time.


*Search For File:
This allows you to search for files that begin with a certain
number of characters. For example, searching for "A*" would show
all files that start with "A". Searching for "ALL" would find
any files called "ALL.GIF".

*Search By Comment:
This allows you to find files that are commented. For example,
searching for "NUDE" would find all files in which the word
"NUDE" was added in its comment. The search is case insensitive.

List Menu Options:

*List All:
This will list on the screen the entire catalog, with all fields,
one screen at a time. The number of lines per screen can be set
from the OPTIONS menu.

*List Volumes:
This will list on the screen a summary of all volumes. This
includes the number of files on a volume, bytes free, etc.

*Files on Volume:
This will list on the screen all files on a particular specified

Print Menu Options:

All print options allow you to print to STDPRN or a FILE. You
are prompted for this information each time. Both these options
are governed by the number of lines per printer page. This can
be set from the OPTIONS menu. You can also choose to print in
single sheet mode, from the OPTIONS menu.

*Full Report:
This will print all information, one file per line. This
includes name, filesize, resolution, volume, and comment.


*Universal Report:
This will print only name, filesize, and resolution. It is
printed one file per line. This report will contain only the
information that is file related, leaving out information
pertaining to your individual system. This might be useful for
making a trading list.

*2 Column Report:
This will print name, filesize, and volume; 2 files per line.

*4 Column Report:
This will print name, filesize, and volume; 4 files per line.
This will require either a 132 column printer or putting your
printer into condensed mode.

Options Menu:

*Printer Lines:
Allows you to specify the number of lines to be printed on one
page. The default is 55.

*Screen Lines:
Allows you to specify the number of lines to be printed on one
screen before a pause. The default is 24.

Allows you to either comment after every catalog (ON) or only
when chosen explicitly from the menu (OFF).

*Catalog Drive:
This allows you to set the drive to catalog from. The default is
drive A:. It also allows you to toggle between sub-directory
mode and floppy root directory mode.

*Viewer Path:
This allows you to specify the GIF viewer path and filename. You
may also add up to three command line parameters.

*Save Configuration:
This allows you to save to GIFLOG.CFG any changes you have made
to the options.


*Set Single Sheet:
This allows you to tell Giflog to wait after each printer sheet
so you can add a sheet of paper to your printer.

Quit Menu:

This will exit GIFLOG after saving any changes to the catalog
file. You may also exit GIFLOG by hitting the ESCAPE key when
there are no pulldown menus showing. Hitting ESCAPE with a
pulldown menu showing will hide the menu. If you want to exit
the program without saving you can hit Ctrl-C or Ctrl-Break.

Technical Information:

I am providing this information in case your catalog is somehow
corrupted. With the following information you may be able to
salvage your file with a editor. Some unpredictable events may
cause errors. Things like corrupt GIF file may cause data file
errors. If your data file is getting corrupted somehow, let me
know about it. The program has very little error checking and it
assumes you will give it the right data.
This is the format of the GIFLOG.CAT file:

{Number of volumes} {Number of files}
Volume entry 1
Volume entry N
File entry 1
File entry N

Volume entry:

{Volume Name}
{Zero byte}
{Volume Index number}
{Files in Volume}
{Bytes free}
{Bytes Used}


File entry:

{File Name}
{Index number}

If there is no comment a "/" is put in the comment field.


I cannot and will not take any liability for the use or misuse of
this program. By using Giflog you automatically agree to this. I
use this program everyday and have not found anything dangerous in
it. This is just a precaution on my part.


By all means pass this program around. All I ask in return is:

1) Do not remove my name or copyright.
2) Distribute the program with all the original files.
3) Contact me by one of the below means, so I know who
is using the program. This is the only way I can
contact you with bug fixes, updates, and
improvements. I would also like your comments and

If you feel this program is useful and you use it regularly send
me some GIF files. My mailboxes (both email and US Mail) are
always open for quality GIFs of any content. Or you may want to
send me a list of your favorite FTP sites.

v1.0 - Initial Release



The previous version didn't seem to work on all machines. The
problem seemed to occur on older machines with older BIOS dates.
Most of the trouble is on 8086 level machines, but the problem
did occur on at least one 80286 level machine. I think this
problem is corrected in v1.1. I have tested it on a true IBM XT
and AT and it has no problems. If Giflog locks up your machine,
or doesn't work as it should please contact me with a complete
list of your hardware. In this list try to include processor,
graphics display, BIOS version and date, DOS version, and any
TSRs that you have installed.
