Tree86(tm) is a product of THE ALDRIDGE COMPANY 2500 CityWest Boulevard, Suite 575 Houston, TX 77042 (713) 953-1940 Fax: (713) 953-0806 Copyright DLAC 1992, All rights reserved Tree86 Version 4.01 This file contains late breaking information not contained in the manual. ADDITIONS OR CORRECTIONS TO THE MANUAL USAGE NOTES HELPFUL HINTS ADDITIONS OR CORRECTIONS TO THE MANUAL Files on Tree86 Diskette, page 7 Tree86 uses 366K if you copy every file on the distribution disk to your hard drive. The required files take only 164K of your hard drive. If you want on-line help and the configuration program, total disk space required is 211K. Information about ALT/edit is contained in the EDT.DOC file instead of a file named README.EDT. The file EDTWS.EXE is not on the diskette. (EDT.EXE is the same file). README.BAT runs the viewer and displays the README.T86 file and EDT.DOC. Tree86 V4 is DESQview compatible. The files called Tree86.DVP and Tree86.XPM have been optimized to run in DESQview X and assume that Tree86 is in the C:\Tree86 directory. NOTE: You should avoid JOINING DRIVES when you are running Tree86 under DESQview because DESQview does not control the disk subsystem and may not be able to find itself or the things it needs to operate. Command Line Parameters, page 8 Tree86 uses a new faster method for copying files by reading them into a buffer and then performing the copy from memory. There may be times when this operation slows down performance instead of speeding it up. If this occurs, a command line switch is offered to disable the read-ahead. Use the /r parameter after the Tree86 command at the DOS prompt. Example: Type: Tree86 /r Cursor Movement, page 11 To scroll through all files or directories beginning with a specified letter, press the left [Shift] and right [Shift] simultaneously. Repeat the letter to display the next occurrence. This is a change from previous versions since you can now press [Shift] and type all or part of a name to move the cursor to the directory or filename that matches. The left arrow key moves up the tree to the directory above at the same depth as the cursor. The right arrow moves down the tree in the same way. [Ctrl][Home] moves the cursor to the parent directory in the branch that contains your cursor. It also moves the cursor to the top of a joined drive. [Ctrl][End] moves the cursor to the last directory in the branch that contains the cursor. It also moves the cursor to the bottom of a joined drive. DIRECTORY, Cut & Paste, page 17 If you begin a Cut & Paste from the Directory pulldown menu, and then press [Esc], Tree86 will finish the subdirectory on which it is working, then display the "Canceled" message. Since Tree86 starts the Cut & Paste process from the last subdirectory, you may have two or more subdirectories of the same name in different locations on your disk. You may have to use Cut & Paste again to cause your tree structure to display as you wish. IMPORTANT!! DIRECTORY, Wipe Directory, page 18 This option on the Directory pulldown menu is the same as the Kill function except that the directory structure remains intact. This means that all files in any directory under the cursor in the same tree branch will also be deleted. WARNING: Use this feature carefully. CHANGE, Join If you have joined drives from the Change pulldown menu and your computer hangs without having first unjoined them, the joined drives may not appear as valid drives. If this occurs, unjoin the "missing" drive by typing at the DOS prompt, JOIN [d:] /D where d is the drive letter of the drive that will not display. When you return to Tree86, that drive will be available. If Tree86 displays subdirectories that are not actually available, relog the drive by pressing [C][R] and the drive designator. NOTE: You should avoid using the Join option when you are running Tree86 under DESQview because DESQview does not control the disk subsystem and may not be able to find itself or the things it needs to operate. CHANGE, Set Log Level, page 22 The log level displayed in the Change pulldown menu is the level that will be in effect the next time you change the log level. Because Tree86 keeps directory information in memory, the log level may vary on different drives depending upon when you changed it. For example, if you have already logged drives C and D and then you change the log level to 4 and log drive G, drive G will be displayed 4 deep. When you change back to C or D, the entire subdirectory structure will still display on C or D. Log level 4 is displayed, the next time you access the Change pulldown menu. If you activate log level without changing the number, the current drive changes to level 4. UTILITIES, Backup/Archive, page 28 In addition to specifying your archive utility name to use the optional command line parameter, you must specify any parameters needed by the utility. Then specify the target filename. SEPARATE each item by the underscore _ instead of a space. Now Tree86 will pass the tagged files in sequence to the archive utility. Be sure to tell Tree86 the path to the filename if it is not included in your path statement. EXAMPLE: At DOS if you type LHARC a i:\save from the subdirectory containing LHARC, then on the Tree86 command line, you would type: Tree86 /a:c:\util\arc\lharc_a_i:\save. Other programs: To use this option for other programs to which you want to pass a list of filenames sequentially, you may want to write a batch file. Specify in the batch file %1 for the input from the tagged list of files. By using the batch file option you are not limited to the command line structure (variables listed before target filespec). EXAMPLE 2: To edit a number of tagged files in order to change your address in all of them, you could call up the editor from the Tree86 command line and sequentially edit each file you tagged. You would type: Tree86 /a:EDT EXAMPLE 3: To run a tape backup program with a different command structure, you could write a batch file containing the command structure, then run the batch file from the command line for Tree86. EXAMPLE 4: Run several programs in sequence. Make batch file with the first and only line saying %1. Say you call it RUNTHEM.bat. Now at the Tree86 command line type: Tree86 a:/RUNTHEM. Then tag executable files (being sure the list is in the order you want to run the programs). Use this same concept to run BASIC programs in sequence. For all these examples, tag the applicable files and press [U]tilities [B]ackup to activate. UTILITIES, Copy/Move Files, page 27 When you have tagged files, then selected Copy or Move from the Utilities pulldown menu, Tree86 displays the amount of space available on the target with the options: yes, no, confirm, overwrite, replace. The replace option is not documented in the manual. If you choose [R] for replace, when there are identical files on the target, Tree86 checks the date of the target file. If it is earlier than the source date, it overwrites the file automatically without prompting. UTILITIES, Backup, page 28 If you have joined drives and then select Backup from the Utilities pulldown menu, you may see the DOS error messages "Invalid drive in search path," "Invalid drive specification," and "COULD NOT ALLOCATE SEGMENT." Cancel Join before performing a backup. NOTE: Xcopy from the Utilities menu can be used in these conditions. Xcopy will copy tagged files to a floppy drive and create the subdirectory structure as it copies the file. A simple Xcopy back from the floppy will restore your files on the hard drive in the same subdirectories. UTILITIES, Resource Memory, page 34 When you select this option from the Utilities pulldown menu, Tree86 uses View86 to display the contents of MAP86. If either View86 or MAP86 is missing, you will see an error message. Tree86 checks for View86 first. Command Buffer in TreeDOS, page 46 You can still erase all previous commands by pressing [Ctrl][F5]. [Ctrl][PgUp] does the same. However, [Ctrl][PgDn] will now delete from the buffer the line showing at the DOS prompt. If no command is displayed, [Ctrl][PgDn] erases the next buffer entry. ERROR MESSAGES, Access Denied, page 62 DOS places a limit on the number of files that can be placed in a root directory. If you see Access denied and can not even make a new directory, this is probably the problem. Delete a file, make a new directory and copy the remaining files into the new directory. ERROR MESSAGES, Access Denied This error displays when attempting to edit a read-only (or system or hidden) file using ALT/edit. Change the file attribute so the read-only attribute is off before trying to edit. Press [Alt][F][Q] to return to Tree86. ERROR MESSAGES, Cannot Paste parent to its subdirectory This message displays when you try to move a subdirectory higher in the directory structure to one subordinate to it. ERROR MESSAGES, Log Level setting is too low If you attempt to Kill or Wipe a directory when the highlighted directory contains other directories that are not displayed, this message appears and Tree86 does not erase the directories. Change the Log Level to see what other directories exist. ERROR MESSAGES, Out of Memory This message displays when you have reached the maximum amount of memory available for performing a function within Tree86. See USAGE NOTES below for suggestions on ways to increase the available memory for performing the task you are trying to do. USAGE NOTES Users of DR DOS 6 may have problems with a few features. Please call regarding the status of a free replacement disk. When you copy files from one subdirectory to a directory on a different drive, the number of bytes and files is not updated on the target tree until you press [Enter]. Earlier versions of Tree86 use [B] on the Find menu for files that have not been backed up. The [B] command now displays files in the branch of the tree beginning at the highlight. Use [N] for "Not" backed up. Earlier versions of Tree86 display the options to select tagged files or file at cursor for Utilities operation in the reverse order. Earlier versions of Tree86 have a different default for altering attributes. When the attribute mask displays, press [C] to change to Change All to use like the old Tree86. When you escape from a packed file copy, the cursor will return to the top file in the list which has not yet been copied. Then, if you want to restart the same list, untag the files above the cursor. Some of the files below the cursor may have already copied and you will see the overwrite message unless you select [O] to overwrite automatically. Be aware that on extremely large drives, there will be a delay to relog the drive when you CHANGE, Log Level or CHANGE, Branch Log. "Out of Memory" If you see an Out of Memory message, there are some ways to obtain more memory for use by Tree86. While the subdirectory limit is 2000, the number of files on which Tree86 will operate is affected by the amount of free lower conventional memory. The amount of free memory divided by 32 equals the number of additional files Tree86 can accommodate. Some methods for freeing up additional memory are: 1. Backfill video memory using QEMM (VIDRAM) or 386max. 2. Remove TSRs (memory resident software) or load them high. 3. Do not use Tree86's zoom mode. 4. Substitute our Cache86 for your disk cache program. Cache86 is the smallest disk cache program available. 5. Remove from memory the drives that have been logged before joining drives. 6. Have expanded memory available. The maximum amount of EMS Tree86 will use is the sum of the amount of your free lower conventional memory (before running Tree86) plus 64k. MAP86 Map86 /e/u reports free memory which includes lower AND upper conventional memory that is unused. This sum can result in MAP86 reporting more free memory than the Total. HELPFUL HINTS One of our users passed along this suggestion for use with removable CD-ROM or other large drives. In conjunction with configuring Tree86 with Instant Log on, he copies the Tree86.DTA file to a file called CD1.DTA, CD2.DTA, etc. Then, he uses a different batch file for each drive when he wants to run Tree86. The batch file first renames the appropriate CD data file to Tree86.dta, and then runs Tree86. This causes the tree structure to appear immediately and eliminates the delay of waiting for Tree86 to relog these drives. To avoid the read-ahead feature in copy and xcopy routines, use the command line switch described above for insertion on page 8. The command line option to run an archive utility program can be used to run any DOS command so long as the modifying parameters are specified first and the target filespec is the last thing on the command line. Example: to send a series of files via FAX or to view several incoming fax files. See above UTILITIES, Backup/Archive. Thank you for using Tree86. We welcome comments and suggestions, and look forward to hearing from you.
