Introduction Hello and thank you for taking the time to read this manual. I hope that you find Disk OrGanizer useful. 1.2. Shareware Disk OrGanizer is not a public domain program. Copies of Disk OrGanizer for personal use are free, but if you find Disk OrGanizer of value, you are encouraged to make a gift ($20 suggested) and become a Disk OrGanizer supporter. You may also register your copy of Disk OrGanizer for $30 and receive a disk and manual along with notification of future versions. A license is required for use of Disk OrGanizer by corporations and institutions, and for its commercial distribution. If you don't support shareware it will go away. 1.3. Purpose A disk that has been in use a while will usually become slower accessing the data and programs that have been stored on it. This is due to two problems: o The disk has become fragmented. o There are deleted entries in directories. Disk OrGanizer will solve these problems and make your disk run like new. If the size of a directory decreases enough after removing the deleted entries Disk OrGanizer can also recover some disk space. Disk OrGanizer has been tested with MS-DOS 2.10, 3.01, 3.10, 3.30, 4.01 and 5.0 on logical drives as large as 600 megabytes. It is believed that Disk OrGanizer will operate on any MS/PC-DOS disk. Disk OrGanizer performs extensive tests before it starts to move data, to make sure that the File Allocation Table (FAT) and directories are in good repair. 1.4. Installation You should BACK UP your hard disk before you run Disk OrGanizer. To install Disk OrGanizer, you need only copy it to a directory on your PATH. You can test Disk OrGanizer by typing the command: DOG [d:] /TEST Disk OrGanizer 1 1. Getting started ---------------------------------------------------------------------- 1.4. Installation d: is an optional drive specifier. (The []'s mean optional and should not be typed.) If no drive is specified the current drive will be used. If Disk OrGanizer reports errors and you have not run Disk OrGanizer before, you should run CHKDSK with the /F switch and repair the disk. If you have not backed up your disk Disk OrGanizer will warn you as to how many files may need to be backed up. PLEASE back up your disks before you run Disk OrGanizer. Disk OrGanizer will also list any files that are open on on the disk that you are organizing. Disk OrGanizer will not be able to move these files nor pack the directories that they are in. If you have used other disk defragment programs before, and have had no problem, it should be safe to run Disk OrGanizer. Disk OrGanizer will move HIDDEN files, most other disk defrag- menters don't move these files. If you have not run any disk defragment programs before you should read the rest of this chapter. 1.5. Background programs Disk OrGanizer reads and writes to the disk directly. If a pro- gram tries to write to the disk while Disk OrGanizer is operating, data may be lost. You should not run Disk OrGanizer on a disk that you know will be written to. Programs that are likely to write to the disk are printer spoolers, multitasking programs like Windows or DesqView, switching programs and net- work programs. If you have FASTOPEN installed on your computer you will need to reboot your computer after you run Disk OrGanizer. Some background programs leave files open all of the time. Disk OrGanizer will not move files that are open and it will not pack a directory that has open files in it. If you do not know if you have these programs on your computer I would suggest that you run Disk OrGanizer from a floppy disk as described in the Quick Start section. Disk OrGanizer 2 1. Getting started ---------------------------------------------------------------------- 1.6. Copy protected programs 1.6. Copy protected programs Disk OrGanizer may make some copy protected software unusable. It is recommended that you remove any copy protected software from your disk before you run Disk OrGanizer, if you can't determine its compatibility with Disk OrGanizer. 1.7. Power failure Disk OrGanizer can recover from a power failure or reboot. If a power failure or inadvertent reboot occurs while Disk OrGanizer is running you should run Disk OrGanizer again as soon as possible. Disk OrGanizer will report any errors that it finds on the disk and ask you if you would like to repair them. If you answer yes to all of the questions Disk OrGanizer will repair the disk and then continue operation as normal. You should not use any third party CHKDSK type programs that recover lost clusters. If you use CHKDSK you should NOT make the lost cluster chains into files. 1.8. Quick start If you would like to defragment your disk and get back to work without having to read the rest of this manual the simplest and safest way to run Disk OrGanizer is described here. The first thing to do is to find an old or unused floppy disk. Then format this disk with a copy of the system. FORMAT A: /sys Copy DOG.EXE to the floppy disk. COPY DOG.EXE A: You may need to create or copy CONFIG.SYS on the new disk if you have disk drivers or an EMS memory driver that needs to be installed. Reboot your computer (Ctrl-Alt-Delete) with the new disk in- stalled in the A: drive. DOS will ask you for the date and time. This is because there is no AUTOEXEC.BAT file. Enter the correct date and time. Run Disk OrGanizer on your hard disk. DOG C: /AUTO /CRC /TRUNCATE Disk OrGanizer 3 1. Getting started ---------------------------------------------------------------------- 1.8. Quick start Disk OrGanizer will test the disk (like CHKDSK), give you a report, analyze the disk to determine the best place to have the directories and files on the disk. Tell you how many directories need to have deleted files removed (packed), tell you how many directories can be made shorter (truncated) and tell you the number of clusters that it will have to move to defragment the files and directories on the disk. You will then be asked if it is OK to write to the disk. If you answer no to this question, Disk OrGanizer will quit without ever having written to the disk. If you answer yes, Disk OrGanizer will pack the directories, truncate the directories and then start moving clusters. While Disk OrGanizer is moving clusters you will see the fol- lowing message: X nnnnn - elapsed time 0:00:00 estimated 0:00:00 X is either R)eading, S)orting, C)omputing CRC, W)riting, T)esting CRC, L)inking new clusters or U)pdating FAT and directories. nnnnn is the number of clusters that have been moved. Elapsed time is the amount of time Disk OrGanizer has been moving clusters and estimated is the approximate amount of time it will take to organize the disk. You can quit from Disk OrGanizer at anytime by pressing the es- cape (Esc) key or a ^C. Stopping Disk OrGanizer while it is moving clusters may cause extreme fragmentation, rerun Disk OrGanizer as soon as possible if you abort while it is moving clusters. If you think that Disk OrGanizer has stopped running, press the space bar, you should then hear a beep within a few seconds. When it is done it will check the disk once again, give you a new report and then exit. You should then remove the floppy disk from the A: drive and reboot your computer. You should notice that the programs on your disk load a little faster. If Disk OrGanizer truncated some directories you will also have more free disk space. Disk OrGanizer 4 2. Using Disk OrGanizer ---------------------------------------------------------------------- The purpose of Disk OrGanizer is to speed up the access of files on your disks. There are two things that slow down access of data; deleted files in directories and fragmented files. The actual placement of files on a disk has very little to do with the amount of time it takes to load a file. Most disk defrag- ment programs take a long time to run and this keeps people from running them often. Disk OrGanizer has complex algorithms that allow it to defrag- ment all of the files on a disk while moving very few clusters. Although Disk OrGanizer can control the placement of files and directories on the disk, I would suggest that you refrain from using this feature, as it can greatly increase the number of clusters that Disk OrGanizer will need to move and give you very little benefit. The exception to this are dirctrories that are read often, such as the directories on the PATH, which you may want to move near the File Allocation Table (see the AUTO command.) 2.1. Modes The mode determines how Disk OrGanizer will organize a disk. FILL - mode will defragment files and put them as close to the FAT as possible, FILL will not leave any free space between files. FILL may leave files fragmented around BAD disk sectors and unmovable files. This mode gives you all of the benefits of that you get from other disk defragmenter, but only takes a fraction of the time to run. FAST - mode will defragment all files and attempt to put them in one area of disk space, FAST may leave gaps of free space between files. QUICK - mode is like FAST mode but does not try as hard. DEFRAG - mode will defragment the files on the drive without concern for there placement. The following modes will more than likely cause all of the files and sub-directories on a disk to be moved. DATE - mode will put the files on the disk oldest files first (closest to the FAT). Using this mode once in a while, it can take a long time to run, may decrease the number of clusters that Disk OrGanizer will need to move with the FAST or FILL mode. DIRECTORY - mode will put the files on the disk in the order in finds them in the directories. That is the first file or sub-directory in the root directory will be closest to the FAT (also refered to as LOW) followed by the second file in Disk OrGanizer 5 2. Using Disk OrGanizer ---------------------------------------------------------------------- 2.1. Modes the root, etc. The following modes are for compatibility to older versions. They are of little use. FRAGMENTED - This will put all of the files that are not fragmented on the disk first and will then put the fragmented files on the disk. Using this function will slowly put all of the files that change size away from the FAT. This mode does not work well if you have BAD clusters or system files other than DOS on the disk. PACKED - This leaves the files in the same order as it finds them on the disk, by cluster. 2.2. Switches CRC - will cause Disk OrGanizer to read data after it is written to the disk and test to make sure that it was written correctly. BATCH - tells Disk OrGanizer to suppress all prompts. This is useful for running Disk OrGanizer from a batch file. If this switch is set any error will cause Disk OrGanizer to terminate. NOVERIFY - tells DOS not to verify data written to the disk. (see VERIFY in your DOS manual) This will increase the speed of Disk OrGanizer but will allow data to be lost. This switch should not be used on a floppy disk, but may be used on a hard disk at your own risk. This is for people to whom speed is more important than data integrity. If you have set the CRC switch then Disk Organizer will verify the data and you can include this switch to improve performance. 2.3. Command line syntax The Command line syntax to run Disk OrGanizer from the DOS prompt is: DOG [d:] [orderfile] [/commands] [/mode] [/switches] (The []'s mean optional and should not be typed.) d: is an optional drive specifier if no drive is specified the current drive will be organized. Orderfile is the path and filename of the order file. If this is not included Disk OrGanizer will look for a file called ORDER.DOG in the root directory of the drive being organized and if it does not find that it will look in the environment for Disk OrGanizer 6 2. Using Disk OrGanizer ---------------------------------------------------------------------- 2.3. Command line syntax DOG=d:\path\filename and use that file. If no orderfile is found the DOS NUL device is used. If you have an orderfile and don't wish to use it you can tell Disk OrGanizer to use the NUL file as an orderfile (ie. DOG NUL /AUTO). Commands consist of AUTO and TRUNCATE. Mode tells Disk OrGanizer where to place the files on the drive. You must supply a mode to suppress the shareware sign-on message. The mode can be set on the command line or in an orderfile. Switches allow you to control several options as to how Disk OrGanizer will test the data that is moved and interact with the operator. Switches can be set on the command line or in an orderfile. 2.3.1. Command line commands TRUNCATE - tells Disk OrGanizer to truncate all sub-directories. AUTO - tells Disk OrGanizer to put the directories defined in the PATH environment variable first, followed by the file definded by the COMSPEC environment variable, then all of the other directories. If no other mode has been specified it will then order the rest of the files as if the /FILL mode was set. 2.4. Orderfile syntax The orderfile can be used as a simple configuration file or can be used to tell DOG the exact order that you would like to have your files on a disk. Modes and switches that are given on the command line will override those in the orderfile. You may find it more convenient to run Disk OrGanizer from a batch file than to use the orderfile feature. Again I would like to point out that the placement of files has little affect on the speed at which they can be read. If you use the AUTO command line command you may not end up with what you expected. (See listing 2.1) 2.4.1. Setting the mode To give a mode in the order file enclose it in square brackets ([]). A mode must be given on the command line or in the order file for Disk OrGanizer to run. For a description of the modes see above. A mode given on the command line will override the mode in the ORDER file. Disk OrGanizer 7 2. Using Disk OrGanizer ---------------------------------------------------------------------- 2.4.2. Setting switches ________________________________________________________________ Listing 2-1: A very simple ORDER.DOG file ; The []s must be included. [FILL] ; set the mode ; The AUTO command line command appends [PATH] ; these three orderfile commands [COMSPEC] ; to the end of the orderfile. [ALLDIR] ; ; And to truncate all of the directories [TRUNCATE ALL] ; ________________________________________________________________ 2.4.2. Setting switches Switches can be specified in the orderfile by enclosing them in square brackets ([]). (See the section on switches above.) 2.4.3. Order file Commands The area of the disk close to the FAT is called the LOW area and the area away from the FAT is called the HIGH area. Any file that is not named anywhere in the ORDER.DOG file is said to FLOAT. In making this file you should name as few files as possible. The following three commands are a shorthand for file and directory names. PATH - is the same as listing all of the directories in the PATH environment variable that are on the drive being organized. COMSPEC - The filename given in the COMSPEC environment variable is used if it points to the drive being organized. ALLDIRECTORIES - Is the same as listing all of the directories on the drive. The following commands tell where to place named files. LOW - tells Disk OrGanizer to place the files described by fol- lowing filenames close to the FAT. This also affects the FREE command. (see below) HIGH - tells Disk OrGanizer to place files described by follow- ing filenames away from the FAT. This also affects the FREE command. Disk OrGanizer 8 2. Using Disk OrGanizer ---------------------------------------------------------------------- 2.4.3. Order file Commands ________________________________________________________________ Listing 2-2: Sample ORDER.DOG file ; [DEFRAGMENT] ; if no mode is given on the command ; line use DEFRAGMENT [FORCE] ; \COPYPRO.SYS ; I don't want this file to move [FLOAT] [TRUNCATE] ; \DIR_A\ ; Truncate sub-directory DIR_A, but let ; it FLOAT. ; [LOW] ; Set move files LOW. \DOS\ ; Truncate sub-directory DOS, and put it ; next to the FAT. [ENDTRUNCATE] \COMMAND.COM ; COMMAND.COM will be placed after \\DOS. [FREE 500] ; leave some room ; [HIGH] ; set move files HIGH. \AUTOEXEC.BAT ; As this file is used only once, on ; reboot, we can move it away from the ; FAT. \CONFIG.SYS ; another seldom used file. \ORDER.DOG ; This file will be place just in front ; of CONFIG.SYS ________________________________________________________________ FORCE - tells Disk OrGanizer not to move the files that follow. If you are going to FORCE file you should do it before you place files LOW or HIGH. FLOAT - tells Disk OrGanizer to ignore the files that follow. This is used if you wish to TRUNCATE a sub-directory but don't want to put it LOW, HIGH or FORCE. NOTE: in future releases this may be used this to allow SYSTEM files to be moved. These commands control whether named directories will be truncated. TRUNCATE - sub-directories named between TRUNCATE and ENDTRUNCATE will have there size changed so that they will use as little space as possible. ENDTRUNCATE - see TRUNCATE above. The following command will force clusters to be left free. Disk OrGanizer 9 2. Using Disk OrGanizer ---------------------------------------------------------------------- 2.4.3. Order file Commands FREE nnnn - tells Disk OrGanizer to leave nnnn (a number) clusters of free space after the last file named in the order file if files are being placed LOW or before the file if files are being placed HIGH. Disk OrGanizer ignores this command if there isn't enough free disk space. The nnnn may be replaced with an asterisk (*) if you want all available free clusters in a location. 2.4.4. File identifiers A file identifier is a string that starts with a backslash (\), has zero or more sub-directory names, separated by backslashes (the Path) and ends with a filename or sub-directory name. A file identifier ending with a sub-directory name can be followed by an optional backslash. It is important to understand that a sub-directory is a file with a special format and that Disk OrGanizer treats sub- directories just like files in the orderfile except that sub- directories can be TRUNCATED. You must always include the full path of a file or sub- directory. Wildcards may be used in filenames. But please note that in- cluding a large number of files in the ORDER file can greatly increase the amount of time it take Disk OrGanizer to organize a disk. 2.4.5. Comments A comment starts with a semicolon and ends with a carriage return. Disk OrGanizer 10 3. Licensing and support. ---------------------------------------------------------------------- 3.1.
