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. Highlights: -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 2 - WHY USE PURGE? ------------------ 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 3 - INSTALLATION ---------------- 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! Troubleshooting: ---------------- 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 4 - USING PURGE --------------- 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. NOTES: ------ - 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 consistently. - 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. Troubleshooting: ---------------- 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 help. _______________________________________________________________ PURGE V2.22 Documentation - Blue Ridge Software, Inc.

The author disclaims all warranties, expressed or implied, including, without limitation, the warranties of merchantability and of fitness for any purpose. The author assumes no liability for damages, direct or conse- quential, which may result from the use of PURGE." PURGE is a "shareware program" and is provided at no charge to the user for evaluation. Feel free to share it with your friends, but please do not give it away altered or as part of another system. The essence of "user-supported" software is to provide personal computer users with quality software without high prices, and yet to provide incentive for programmers to 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 PURGE immediately (However Blue Ridge Software, Inc. must still be advised so that the distributor can be kept up-to-date with the latest version of PURGE.). You are encouraged to pass a copy of PURGE along to your friends for evaluation. Please encourage them to register their copy if they find that they can use it. All registered users will receive a copy of the latest version of the PURGE system. _______________________________________________________________ PURGE V2.22 Documentation - Blue Ridge Software, Inc. Page 10 APPENDIX A - WHAT IS SHAREWARE?/WHAT IS THE ASP? ------------------------------------------------ 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. _______________________________________________________________ PURGE V2.22 Documentation - Blue Ridge Software, Inc. Page 12 APPENDIX B - THE ASP OMBUDSMAN ------------------------------ 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 49442 or send a CompuServe message via CompuServe Mail to ASP Ombudsman 70007,3536. _______________________________________________________________ PURGE V2.22 Documentation - Blue Ridge Software, Inc. Page 13 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. SOON TO BE RELEASED: -------------------- 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. _______________________________________________________________ PURGE V2.22 Documentation - Blue Ridge Software, Inc.
