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.

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, 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 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 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).
