CHKPATH - A Path File Conflict Detection Utility

Authored by Alan Jay Weiner, Technology 21

version 1.01

As software is installed and upgraded, it is possible for copies of
programs to be placed in more than one directory in the path. In
some cases, these are the same program, and are simply redundant
copies; the only penalty is wasted space. In other cases, they may
be different versions of the same program, with different
capabilities. Or, they may be completely different programs or data
files, which just happen to have the same name.

Many programs search for files (either data files, or additional
program files) along the path. If there are conflicting files in the
path, the wrong file may be used. This is analogous to being dropped
into a city with the wrong map. Consequenses of using the wrong file
vary from none to catastrophic. Often the program will work, but
with intermittant problems. This can be difficult to diagnose; the
software may have worked in the past, when the correct file was being

Reorganizing a disk, or changing the order of directories in the
path can cause a system to go psychotic, if the wrong files are
found. Often the problems will not become apparent until well after
the problem is caused, making diagnosis difficult.

CHKPATH has been created to detect this situation. It checks all
files in all directories in the path, and reports any conflicting
files. It is completely safe to run; it does not attempt to fix
anything, it merely reports the conflict. This protects you in the
event that a file only appears to be a conflict, but is actually

CHKPATH's report is in the form:

There are 13 conflicting files

As CHKPATH checks the path, it will list any files which are in
conflict. A file is considered to be in conflict if it has an
identical name and extension, but is in a different directory. If
the initial file is executable, files are in conflict if they have
the same name and any executable extension, in the same or another

Executable files have an extension of .BAT, .COM, or .EXE. These
files are searched for by DOS, when they are executed from the
command line. CHKPATH will report the file which DOS will execute as
the initial file, and any conflicts.

You should review each set of conflicts and determine which is the
correct file to remain in the path. In most cases, one of the files
should remain, while duplicate instances should be erased. In some
cases, the latest version is not the first file found. In that case,
usually the older files should be removed.
Occasionally, files must remain in conflict. These may be cases such
as DOS 5's "DOSSHELL" files. DOS 5 supplies DOSSHELL.COM which, when
executed, loads the file DOSSHELL.EXE. Since they are both in the
same directory, they rely on the order that DOS looks for files.
However, since they have the same name, and executable-file
extensions, CHKPATH will report them as a conflict.
This can also occur with data files. In the sample report shown,
there are files named README.TXT in both C:\DOS and D:\WINDOWS. In
this particular case, it is unlikely that any other program will refer
to these files, so it is unnecessary to resolve the conflict.
Some data files may be used by programs. If the program searches
the path, it will find the first file listed. For these programs, it
may be necessary to force them to use the required file from the
necessary directory. This is usually possible with a command-line

The concept of Shareware

Often, software is purchased from a store or distributor. The
purchaser must pay for it before they can try it - even to determine
if it is suitable for their purposes. The price includes more than
just the cost of the software. Packaging, printing, shipping,
distributor overhead, and other costs all drive the price up.

Shareware on the other hand, is a concept which bypasses most of
the costs associated with "normal" software. The distribution is
usually by computerized bulletin board ("BBS") or purchased with
other shareware programs on a low-cost disk. It is also permissible
to provide copies of shareware to others. All files supplied must be
distributed with copies, and they may not be modified in any way,
except for compression (ZIP, ARC or other utilities) to reduce
storage requirements, or to archive all the files into a single file.

Shareware is designed to be sold on a "try-before-buy" basis. Once
it is determined that the software works as intended, and suits the
purpose, the user "registers" as a user. This permits the continued
use of the program.

The shareware is a copyrighted program; the authors retain all
rights to the software, while allowing free distribution. As such,
all users are obligated to register if they intend to continue use of
the program. This is true regardless of where the software was
obtained, even if received from a friend who has registered.

Registering as a user

Only you can determine the value of software to you. With this in
mind, the registration fee is based on a sliding scale: if you get
great value from CHKPATH (perhaps finding a conflict that had been
causing, or would have caused problems) you are requested to pay more
than if no benefit was gained.

My recommended registration fee is: (all figures are U.S. dollars)

no benefit, and I hate the programno fee, but please let
me know why you feel as
you do, and what I can
change to improve it

no benefit, and I'm not going tono fee
run it again

peace-of-mind, and I'll never run$1.00

peace-of-mind benefit - no conflicts$3.00
were found, and I'll run CHKPATH
occasionally to check again

a few conflicts found, and saved me$4.00
future headaches

saved me! conflicts found which were$6.00
causing me problems

I'd like to register, and send me$10.00
the source code. (written in C)

If you feel another amount is more appropriate, please select
that amount. If it is $10 or more, you will be sent source code.

If you are running CHKPATH on multiple machines, with multiple
users, a site license is required. The rates area:

2 to 5 machines $15.00
6 to 25 machines $25.00
26 to 50 machines $50.00
over 50 machines $1.00 per machine

All site licenses include source code license. A single copy
of the source code will be issued, and may be used on all machines.
