CQvis Directory Backup Extension




DBE Views:Screen-shots of Program DBE.EXE in action





This is the DBE opening screen when you first start up; i.e., when there is no DBCONFIG.CFG file.


When you start DBE, the right pane shows a mnemonic key-help display, and the current pane, showing the selection bar if files are present, is the left one.




Pressing the BackSlash key (or the numeric keypad '5' key (you may need to press Shift-5)) opens the SelectDisk/SelectLevel window, and mnemonic key help is shown in the opposite pane prior to your pressing another key.




The file viewer is shown here with two files loaded (the same file, actually; the lower window is the current one, as the highlighted filename below the file display area shows. The view mode is TextOnly/SplitH. (F1/F6)




Here, the same file is shown in TextOnly/SplitV mode. (F1/F7)




Above, the first (or upper or left) view window is active, as the highlight on the upper filename shows, and the view mode is TextOnly/Full. (F1/F5)




Above is the main display, showing two different directories, F:\PROGBOOK.2 and F:\GM. On the right, the pink blocks show the projected used space on the disk and the highlighted area indicates the amount of space currently used, with the disk size scaled to the length of the display area for this and empty space indicated by blue dots.

In the left pane, two files are tagged with the COPY tag, and the current file has also been buffered, as indicated by the bright white and yellow color of the filename (seen below the window in the status area because the selection bar obscures the color attributes of the file shown in the list).

The free space on the disk is shown in green, the occupied space in red.




Pressing the '?' key produces the status display, as shown above. The top line shows the disk volume label followed by the directory path and filename of the current file. At the bottom, the COPY tag status and the target state (none) are shown; and since the file is buffered, the FinBuf and BEnabled status bits are set (and, thus, highlighted). If a target had been assigned to this file, the target name would appear following the filename on the top line of the display.

Note also the green 'diamond' characters following the filenames CH1A, etc. These signify that the files are on the Selected List.




Here, the current file, CH1B2, has been MOVE tagged, and since it is also a Selected file, the SEL and MoveTag states are indicated in the status area.




Here, the selection bar has been moved down to the file DECOR.TXT and the 'C' key pressed. Since no target was assigned to this file, the target setting option is activated. Note that the current target is F:\GM, which is the destination if you would press 'T' at this point.




Above is shown what would happen if you tried to copy the file into the same directory where it resides, without renaming it. Since they are obviously the same file, you might not need to compare them; but what if you wanted to check to see if a particular disk was being read from properly? You could buffer the file when this display appears, and then press '?' to compare the buffered file (already read from the disk) with the file still on the disk (and press Esc or S to cancel the copy process anyway, before copying). The '?' causes a verify of the source and target files, and you can press 'V' to view the point where they mismatch, if indeed there is a mismatch.




Above, a view is shown after 'B' was pressed in the preceding case to buffer the DECOR.TXT file. Now the copy routine wants to do the copy, and you will note that the file labeled SOURCE is in the F:\GM\BUF buffer directory and ready to be copied to the target.




Above, the copy was allowed to proceed, and the file has thus been copied to the buffer and then rewritten over itself, with the buffered copy replacing the original file. (You may have heard of 'refreshing' the magnetically stored data on a disk every few years; well, this is one way it can be done, and you will be able to verify that it was done correctly at each stage.)




Above, drive A: has been read into the right pane, and the Associate option been used to associate the files on drive A: with other files on drive F:
If you scroll the directory, files having the same name appear in the opposite window, scrolling along with the files in the current window. The Slash key turns this display on and off, and it can also be used to quickly look at target files in the opposite window to which files in the current window have been copied.




Above, the '=' key has opened the DiskStatus display, and the lower portion shows the projected capacity for the two active disks (which are being viewed in the two panes of the main display). Pressing PgDn or the Down cursor key at this point would bring up the display shown following:




In this display, a disk can be selected either by entering the number shown at the left or by moving the selection bar. Exiting with the Right or Left cursor keys places the selected disk in the right or left pane (and the currently selected level from that disk will automatically be displayed there).




Here and below are shown the SelectDisk/SelectLevel window, with two different directories on two different disks shown on the right. Note that three of the disks have the same volume label, but that one has the DiskID FV21H4 and the others have the DiskIDs FWAWRW and FVEKM5, which distinguishes them from each other when it comes to DBE's source and target directory assignments to particular directories.



Above, disk FVEKM5 and its current directory are shown. Note that the files are the same as the files in the preceding display of the root directory of the FWAWRW disk. This means that they would be buffered independently of each other in the buffer directory, and DBE would not get them confused (although it might start ignoring multiple copies of the same file on the SAME disk in the SAME directory after you buffer three or four of them... but why you would want to do this I don't know, unless you're having a really rough time reading data from a damaged disk or something and are trying multiple efforts to get what you can back off it and save it somewhere for the time being.).




Above is shown the file Select option, active, and with the DATE and SIZE qualifiers filled in and with the compare tag value ready to be set when the file to be selected is found. (There is only one file, at least in the current window, which would match these selection criteria; but if you had activated it with Global scope, there could be others in other directories or on other disks, which could match these criteria.)




Above, the windows show two different disks which have been read in drive A:, and the COPY, MOVE, COMP, and DEL tags are shown as set for four files in the left window.




Above, the startup of DBE is shown, with the option to choose the location of the DBSYSCON.FIG file active as shown at the bottom of the screen.

Federal law mandates that published material for which copyright is claimed must bear a copyright notice; and at startup, the program name and current version identifier are shown, followed by the copyright notice.

The term CQvis is the acronym for Chromatic Quiddity Visual Information Services

Note that the copyright year 1992 was the year in which the first version, titled DB2, of this program, was completed.




Above, a number of files have been tagged for COPY, and the magenta triangles pointing to the right indicate that the files have been assigned targets which are currently active; i.e., pressing 'P' or 'G' will immediately cause these source files to be copied to the targets which have been set.

The right window shows, however, that the Associated function is in use, and DBE does not copy these files until the Associated links have been removed (press Alt-A and then Esc to do this).




Above, note the LNK status indicating an Associated file, is shown in the status display. The Process and DestDef bits are set when the file's Target is assigned.




Here, four files have been copied from F:\GM to F:\GMTEMP, as you will note from the top line of the display of the current file's status. The files have the word OK next to them in gray, and in addition the target triangle has been changed to a dot which indicates that it is still assigned but is inactive.

The right pane shows the directory F:\GMTEMP with the new file entries shown in gray to indicate that they are new files or are different from the previously existing files by the same name that were present in the target directory.




Above, the Slash key has been pressed to show the targets next to the source files they were copied from.






Here, the List Files/Targets view mode has been turned on. The file numbers are shown at the left of the filenames, and the target numbers are shown at the left of the targets.




Above, two green triangles have replaced the OKs next to the copied files. What has happened at this point is that the 'V' key has been pressed to cause the source files to be verified against the target copies just made. The green triangles appear when the files compared are identical. If you were having trouble copying files from a source disk, you could assign the source disk as the target after copying them to some other location, and then do a compare (and say you're just curious as to whether you read the files correctly from the source).




Here, the Queue is enabled, as indicated by the parenthesized diamond on the top line. Several files in two directories have been tagged and queued. Pressing ?? shows the following view of the queue numbers in the left window: 


Note that when Queue Start mode is in effect, the queue number of the current file is shown preceding the line 1 filename/target information, and this also signifies that the normal Process/Go operation follows the sequence determined by the queue numbers.
