PURGE is a utility which allows multiple file purging
at high speed without using scripts or batch files. PURGE will read
in the current directory and allow you to select any or all drawing
files for purging. PURGE can root out those deeply nested blocks
and layers 100% in a SINGLE pass.

-Multiple File Capability
-Do any or all of:
Blocks, Layers, Styles, Dimstyles, Linetypes, Shapes
-High Speed
-Purge files in a SINGLE pass
-Windowed Environment
-Complete Before-and-After Size Reports
-Compatible with Versions 2.5 - 12

Having used AutoCAD in a production environment for 8 years
now, we've seen how much productivity decreases when the user has to:

a) wait increasingly longer to bring drawings up,
b) deal with the confusion involved with a drawing that
has 26 unused blocks, 10 unused layers, etc. and
c) shell out of AutoCAD to figure out a way of "creating"
an extra 50K of disk space to save their work

The only way we have found to deal with this SOMEWHAT effectively is
through the use of script files and performing a massive purge at
the end of each week. This involves writing a script to bring up
every drawing and invoke the AutoCAD purge command SEVERAL times.
This is necessary since the AutoCAD purge command won't always purge
the drawing in a single pass (PURGE does). If you haven't dealt
with script files, don't worry, PURGE will eliminate this. If you
have used this technique, you know what we're talking about.
We use it in an engineering environment everyday and LOVE IT.

Purge 2.22 is designed for users that have a moderate number of
drawing files. If you require the ability to purge large amounts
of drawings and desire batch capabilities, be on the lookout
for PurgeCL. As a registered user, you are entitled to significant
discounts for any future purge products, including PurgeCL. Please
call 1-606-276-5148 for more information (after 2/1/94).

PURGE V2.22 Documentation - Blue Ridge Software, Inc. Page 1


Quick Start:
If you haven't already, use the install program included with
the Purge files. Simply type 'INSTALL' at the DOS prompt and
follow the instructions. Note that if you wish to use Purge from
any directory, the directory that Purge was installed to MUST
appear in your path. Install will do this for you if you choose
this option. Also, your machine must be rebooted for the changes
to the path statement to take effect.

After installation, move to the directory where some drawing
files exist and type 'PURGE' at the DOS prompt. A list of all of
the drawing files in the directory will appear. Set the PURGE
filters (keys 1-6), use the space bar to tag the drawings you
want to purge and hit ENTER. That's it!


If PURGE doesn't come up when you type PURGE at the DOS prompt, try
the following:
- Go to the directory where PURGE was copied.
- Check to see that PURGE is there by executing the directory command.
If not, try installing PURGE to the directory again.
If it is, make sure that this directory is actually in your
path. Type "PATH" at the DOS prompt and check to see if
this directory is contained in the path.

PURGE V2.22 Documentation - Blue Ridge Software, Inc. Page 2


Use the space bar to tag the .DWG files to be purged and
press ENTER. To purge a single file, simply highlight the desired
file with the cursor keys and press ENTER.

Use the number keys 1-6 to toggle whether any or all of Blocks,
Linetypes, Dimstyles, Layers or Shapes/Styles should be purged. If the
'Defaults' option is off, the current layer, linetype and style will not
be purged (whether or not any entities use these current settings). If
'Defaults' is on and no entities use the current default settings, the
current defaults will be changed to the base settings (layer 0, linetype
continuous, style standard) and the default settings will be purged. This
option is included in case you don't want to purge any layers, linetypes
or styles that are not used but are the current defaults.

Press ESC to quit processing at any time. The current drawing file
being processed will not be purged.

- If ESC is pressed while a drawing is being processed, PURGE
will finish purging the current file, then rewrite the
finished file with the .BAK file. Therefore, no changes
will have been made to the file that was being purged.

- Although PURGE uses a highly-optimized and efficient algorithm
for purging, large drawings can take a long time to purge.
Please don't reboot while PURGE is running - if you need to
stop purging in middle of a number of files, hit ESCAPE.
This will avoid any problems with lost or bad drawings.

- .BAK files are generated automatically. There is no option to
not generate backup files. This was decided on to prevent
the losing the original drawing in case there is a power outage
or hard-disk crash while PURGE is running. We suggest that
the purged drawings be tested in AutoCAD before erasing the
.BAK files to verify that an undetectable "brown-out" or
"kicked-disk" did not corrupt the purged drawing. If proper
precautions are observed, PURGE will provide reliable operation

- The purged drawings will retain the date and time of the
original drawing file. We suggest that you use a date change
utility if you would like the purging date reflected on the
new drawing file.

PURGE V2.22 Documentation - Blue Ridge Software, Inc. Page 3

- Most users have found that having more than 500 files in a
directory is just about the maximum that they could manage.
Therefore, PURGE only allows 250 .DWG files to be processed
at a time (2 x 250 = 500). We suggest that you break your
files into directories of 250 each if you need to process a
very large amount drawings. HOWEVER, be sure to see Page 9
concerning the release of PurgeCL.

If you receive any of the following messages while in PURGE, please
write down exactly where the error occured and give us a call:
- Floating point Error
- Stack Overflow
- Any AutoCAD-generated error when loading a drawing into AutoCAD

Almost all problems involving these errors are a function of your
unique system configuration. Please contact us immediately for

continue to develop new products. If you find this program
useful and find that you are using PURGE and continue to use
PURGE after a reasonable trial period, you must make a reg-
istration payment of $69.95 + applicable tax to Blue Ridge
Software, Inc. The $69.95 + applicable tax registration
fee will license one copy for use on any one computer at any one
time. You must treat this software just like a book. An example
is that this software may be used by any number of people and may be
freely moved from one computer location to another, so long as there
is no possibility of it being used at one location while it's being
used at another. Just as a book cannot be read by two different
persons at the same time.

Commercial users of PURGE must register and pay for their
copies of PURGE within 30 days of first use or their license
is withdrawn. Site-License arrangements may be made by con-
tacting Blue Ridge Software, Inc.

Anyone distributing PURGE for any kind of remuneration must
first contact Blue Ridge Software, Inc. at the address below for
authorization. This authorization will be automatically granted
to distributors recognized by the (ASP) as adhering to its guidelines
for shareware distributors, and such distributors may begin offering

What Is Shareware?

This file will help you understand what shareware is and how the
"shareware system" works. It was written by the Association of
Shareware Professionals (ASP -- a professional association of
shareware authors) at the request of the Shareware Distribution
Network (SDN -- an association of BBS Sysops providing reliable
distribution of shareware around the world), for the express
purpose of giving BBS users a better understanding of shareware.

You've probably heard the terms "public domain", "freeware",
"shareware", and others like them. Your favorite board probably
has many programs described by one or more of these words.
There's a lot of confusion about and between these terms, but
they actually have specific meanings and implications. Once you
understand them you will have a much easier time navigating the
maze of programs available to you, and understanding what your
obligations are, or aren't, with each type of program.

Let's start with some basic definitions.

"Public domain" has a very specific legal meaning. It means that
the creator of a work (in this case, a piece of software) who had
legal ownership of that work, has given up ownership and
dedicated the work "to the public domain". Once something is in
the public domain, anyone can use it in any way they choose, and
the author has no control over the use and cannot demand payment
for it.

If you find a program which the author has explicitly put into
the public domain you are free to use it however you see fit,
without paying for the right to use it. But use care -- due to
the confusion over the meaning of the words, programs are often
described by others as being "public domain" when in fact they
are shareware or free, copyrighted software. To be sure a
program is public domain you should look for an explicit
statement from the author to that effect.

"Copyrighted" is the opposite of public domain. A copyrighted
program is one where the author has asserted his or her legal
right to control the program's use and distribution by placing
the legally required copyright notices in the program and
documentation. The law gives copyright owners broad rights to
restrict how their work is distributed, and provides for
penalties for those who violate these restrictions.

When you find a program which is copyrighted you must use it in
accordance with the copyright owner's restrictions on
distribution and payment. Usually these are clearly stated in
the program documentation.
PURGE V2.22 Documentation - Blue Ridge Software, Inc. Page 11

Maintaining a copyright does not necessarily imply charging a
fee, so it is perfectly possible and legal to have copyrighted
programs which are distributed free of charge. Such programs are
sometimes termed "freeware", though this term was in fact
trademarked by the late Andrew Flugelman and the legality of its
use by others could be questioned. In any case, the fact that a
program is free does not mean that it is in the public domain --
though this is a common confusion.

"Shareware" is copyrighted software which is distributed by
authors through bulletin boards, on-line services, disk vendors,
and copies passed among friends. It is commercial software which
you are allowed to try out before you pay for it.

Shareware authors use a variety of licensing restrictions on
their copyrighted works, but most authors who support their
software require you to pay a "registration fee" -- the purchase
price of the software -- if you continue to use the product after
a trial period. Some authors indicate a specific trial period
after which you must pay this fee; others leave the time period
open and rely on you to judge when you have decided to use the
program, and therefore should pay for it. Occasionally a
shareware author requires registration but does not require
payment -- this is so-called "$0 shareware".

The shareware system and the continued availability of quality
shareware products depend on your willingness to register and pay
for the shareware you use. The registration fees you pay allow
authors to support and continue to develop their products.

As a software user you benefit from this system because you get
to try the software and determine whether it meets your needs
before you pay for it. Authors also benefit because we are able
to get our products into your hands with little or no expense for
advertising and promotion. As a result it is not unusual to find
shareware products which rival retail software that costs several
times the amount of the shareware registration fee.

ASP members' shareware meets additional quality standards beyond
ordinary shareware. Our members' programs must be fully
functional (not crippled, demonstration, or out of date
versions); program documentation must be complete and must
clearly state the registration fee and the benefits received when
registering; members must provide free mail or telephone support
for a minimum of three months after registration; and members
must meet other guidelines which help to insure that you as a
user receive good value for your money and are dealt with
professionally. We also provide an Ombudsman program to assist
in resolving disputes between authors and users. For more
information on the ASP or to contact the ASP Ombudsman, write to
ASP, P.O. Box 5786, Bellevue, WA 98006. You can also contact the
Ombudsman on CompuServe via an EasyPlex (electronic mail) message
to 70007,3536.

This program is produced by a member of the Association of
Shareware Professionals (ASP). ASP wants to make sure that the
shareware principle works for you. If you are unable to resolve
a shareware-related problem with an ASP member by contacting the
member directly, ASP may be able to help. The ASP Ombudsman can
help you resolve a dispute or problem with an ASP member, but
does not provide technical support for members' products. Please
write to the ASP Ombudsman at 545 Grover Road, Muskegon, MI

Appendix C - What other AutoCAD utilities does BRS sell?
We market one other program, AC12TO10. AC12TO10 is identical
to PURGE in terms of look and operation except for it's function.
AC12TO10 allows those users that haven't upgraded to Release 11
or 12 to convert Release 11 or 12 drawings to Release 10. As with
PURGE, there are ABSOLUTELY NO DXFS INVOLVED - all processing takes
place at DOS directly on the .DWG files. In a nutshell, if you
have a client who uses only Release 11 or 12, AC11TO10 is a perfect
alternative to upgrading. See Ralph Grabowsky's review in the
Utilities column of the October, 1991 issue of Cadence. Then
look for a shareware copy of AC12TO10 in the ADESK forum on
Compuserve, your favorite BBS or from your local User's Group.
If you can't find it, give us a call at 1-606-276-5148 - we'll send
a copy right away.

A command-line version of Purge will be available after
February 1, 1994. This version, called PurgeCL, will allow
you to perform unattended batch purges from a script file
as well as a simple entry from the command line. PurgeCL
features extensive logging facilities as well as a multitude
of switches to allow for a flexible environment. PurgeCL
has been tested extensively on networks and shown an average
disk space savings of 20% with an average speed of 20Kbytes
per second. If you have any questions on this product or
would like to receive a copy of PurgeCL (after 2/1/94), please
call 1-606-276-5148.

Changes from V2.2:
- Paperspace viewport layer settings are handled correctly now
- Xref layers will be processed correctly
- Corrected minor bug which caused Purge to "hang"
- Memory requirements are much lower now
- Associative dimension updating has been corrected

Changes from V2.0/V2.01:
- The defaults option has been added by request.
- The shell option has been removed.
- Drawing file dates are no longer changed to the current
date, i.e., the original date of the file is preserved
- Single drawings can be purged by simply highlighting
the file name and pressing ENTER. There is no need
to tag a single file if only one drawing is to be purged.
If any files are tagged and a non-tagged file is highlighted
when ENTER is pressed, the highlighted file will NOT be
purged - only the tagged files will be purged.
- Various minor bugs have been removed including:
a) the correct number of drawings purged is reported now
b) the sort by size function now updates the display
