 ABOUT DUPLICATE FILE FINDER

     If you have a hard disk with many subdirectories, you probably have 
 duplicate copies of some of your files or programs in several subdirectories. 
 It is amazing how simple it is to end up with duplicate files.  It is common 
 to copy a file from one subdirectory to another, and even more common to 
 forget to delete the file from the original subdirectory, resulting in 
 unnecessary duplication of files.  When the hard disk (or floppy) starts to 
 get full, the easiest way to make more room is to delete some of these 
 unnecessary files. Even before the disk starts to get full, these extra files 
 slow down the access time because the computer has more files to search 
 through. 

    Finding all the duplicated files can be very time consuming if you try to 
 do it manually.  ^1Duplicate File Finder^0 (DFF) does all the work for you.  It 
 will automatically read all the file names from all the subdirectories of the 
 disk you specify and check for duplication.  You may then view this list and 
 optionally delete unwanted files from the list and from the disk.  DFF can 
 also give you a printout containing an alphabetical listing of the duplicate 
 files. 
 

 RUNNING DUPLICATE FILE FINDER (DFF)

    When you run DFF, you will see its opening title screen followed by the 
 main menu.  Press F1 while at the main menu to obtain onscreen help on using 
 DFF.  Menu options are selected by moving the highlight bar to the desired 
 choice and pressing the <ENTER> key.  The bar is moved by using the UP and 
 DOWN ARROW keys; you may also press the first letter of a menu option to move 
 the highlight bar to it.  As you cursor through the selections, the bottom 
 line on the screen contains a brief explanation of each option.

 MAIN MENU SELECTIONS:

    Analyze Drive     -- Read all file names from specified drive and 
                         locate duplicate files.

    View Duplicates   -- View the list of duplicate files and optionally 
                         delete unwanted ones.

    Output Duplicates -- Output the list of duplicate files to your printer.
   
 
 ^1Analyze Drive

     You will be prompted for the criteria on which to determine duplication.  
 The default is that the files have the same name.  You may further restrict 
 this to same file size and/or same date and time.  See "Selecting Duplication 
 Criteria" below.  You are then prompted for the drive to analyze.  Press a key 
 from "A" to "Z".  You may also press the ESC key to abort this process. If you 
 have entered a valid drive and there is a disk in the drive, all of the files 
 on the disk will be read.  As each subdirectory is searched, its name will be 
 displayed, as well as the number of files processed so far.  A system with a 
 large number of files and/or a slow processor may take a while to analyze, so 
 please be patient.  If you decide you do not want to analyze the specified 
 drive, you may press the ESC key any time during the search phase; a box will 
 pop up asking you if you are sure you want to abort -- answer appropriately.  
 
     Once all the files have been read, the list of duplicates will be 
 constructed.  You will then return to the main menu from which you may view 
 this list (with optional deletion) or print it out.

    NOTE:  If you have analyzed one drive and then analyze another drive in the 
 same session, the duplicate list in memory from the first is destroyed when 
 the new one is constructed.  Therefore, once you have analyzed a drive, be 
 sure to output it if you think you may want to reference it later.


     Selecting Duplication Criteria

         After selecting "Analyze Drive" from the main menu, you are 
     prompted to select the criteria on which to base duplication of files.  
     By default, the program checks for identical file names.  You may also 
     have it check for same file sizes and/or same date and time.  

         The box displays the two optional criteria, followed by an "off" 
     or "on" for each.  To switch a criteria off or on, move the highlight 
     bar to it and press the Space bar.  Once you are satisfied with both 
     criteria settings, press the <ENTER> key.  You may also press the ESC 
     key to return to the main menu, or the F1 key to obtain onscreen help. 


 ^1View Duplicates 
        
       The list of duplicate files is displayed on the screen.  The last row 
 on the screen contains a list of the movement keys and functions available 
 from within the viewer.   Functions include printing the list (F3), selecting 
 a file for deletion (<ENTER>), deleting selected files (F2), onscreen help 
 (F1), and returning to the main menu (ESC).  

     Browsing the List:
 
         You may browse through the list by using the UP and DOWN ARROWS, 
     PAGE UP and PAGE DOWN, and the HOME and END keys.  The ARROW keys 
     scroll the list by one line.  The PAGE keys scroll the list a screen 
     full at a time (approx. 19 lines).  Pressing the HOME key will send 
     the highlight bar to the first file on the screen; if the bar is 
     already at the top, it will move to the first file in the list.  The 
     END key works in a similar manner toward the end of the list. 

     Selecting Files for Deletion:

         To select a file to be deleted, move the highlight bar to the 
     desired file and press the <ENTER> key.  The <ENTER> key acts a toggle 
     between select and deselect.  If a file is already selected, pressing 
     the <ENTER> key will deselect it.  Selected files (and non selected 
     ones) are displayed as follows: 
                                  Color                Monochrome
     Normal Display 
       Not Selected --  Light Gray on Black     Light Gray on Black
       Selected     --  Bright White on Black   Bright White on Black
                
     Highlight Bar   
       Not Selected --  Light Gray on Red       Reverse Video (dk. on lt.)
       Selected     --  Bright White on Red     Blinking Bar
                
         Repeat this procedure for each file you wish to delete.  When you 
     have marked all of the files you want deleted, press the F2 key to 
     start the deletion process. 

     Deleting Files:

         Once you have marked a file or several files for deletion, press 
     the F2 function key while in the viewer.  A box will appear asking you 
     if you wish to confirm each individual file before it is deleted, or 
     if you want to delete all marked files at once.  We recommend that you 
     confirm each file individually; however, you may, of course, choose to 
     do them all "in one fell swoop".  If you have chosen to confirm them, 
     by pressing a "C" at the prompt, each file name and its path will be 
     displayed in the box, and you will be asked whether or not to delete 
     the file.  Answer "Y" or "N".  A "Y" will delete the file; a "N" will 
     not delete it.  If you elected to delete them all, by pressing an "A" 
     at the original prompt, each file and path will be displayed and the 
     file will be deleted without asking you for confirmation.  

        Regardless of the method of deletion you chose, you may abort the 
     file deletion process at any time by pressing the ESC key.  Any 
     remaining selected files will be not be deleted and you will return to 
     the viewer.  If there are no more duplicate files after the deletion 
     process, you will be returned to the main menu from which you may 
     analyze another drive or quit.

     Printing Files:

         Pressing the F3 function key while in the viewer will print the 
     list of duplicate files.  See the "Output Duplicates" section below.


 ^1Output Duplicates
 
       After selecting this option, you are prompted to ready your printer.  
 Ready your printer by turning it on, setting it to "online", and placing 
 paper in it.  At this point you may now press a key to start printing, or 
 press the ESC key to abort printing.  The list of duplicate files will be 
 printed with the file name in the first column, path name in the second, file 
 size in the third, file date in the fourth, and file time in the fifth.  The 
 drive letter is displayed in the first column of the row containing the 
 column labels.  You may press the ESC key during printing if you wish to 
 cancel the print out. 

 
 ^1OPTIONS FOR RUNNING DUPLICATE FILE FINDER 

    DFF can be run from the DOS prompt with the following options: 

    M     Starts the program in monochrome mode. Use this option if 
          you are using a composite monitor, or an LCD.

    C     Starts the program in color mode.  Use this option if you 
          have a color graphics adapter (CGA, VGA, EVGA, etc.).
    
    Examples:

      >dff M               - Run DFF in monochrome mode.
      >dff C               - Run DFF in color mode

    NOTE:  This program automatically detects the type of monitor being used 
           and adjusts accordingly.  However, due to the wide variety of 
           computer hardware on the market, it is possible that the detection 
           may not work properly on all systems.  This is the reason we have 
           provided the options mentioned above.


    To run this program outside ^1Big Blue Disk^0, type: ^1DFF^0.
