                         ConCat/Split V3.3.2.0
-------------------------------------------------------------------------

ConCat/Split is a Windows Explorer context menu extension that provides
two complementary facilities:

1. A split facility that lets you easily convert a single large file into
   several smaller ones. You can copy these smaller files onto floppy
   disks, or send them through email facilities that will not cope with
   large files.

2. A file concatenation facility that performs the same operation as the
   command line "copy /b SrcFile1+SrcFile2 [+SrcFileN] DestnFile"
   operation. With ConCat, you can append any number of files and store the
   result as a new file, or overwrite one of the original files.

You can re-read this file after installation by clicking the Start ->
Programs -> JD Design -> ConCat -> Readme menu item.




-------------------------------------------------------------------------
			      Installation
-------------------------------------------------------------------------

Run the ConCat program (ConCat.exe) directly from your web browser (if
you're accessing ConCat from our web site), or download it and run the
program from your hard disk, or the supplied floppy disk (if you've
ordered one with your registration).


Setup will copy files to your computer and then prompt you for your
registration information (which you can skip if you're evaluating it).

The last step of Setup informs you that ConCat is installed and briefly
tells you how to use it. If you are upgrading an existing version, setup
may need to restart Windows.

Installing under NT4, Windows 2000 or Windows XP
------------------------------------------------

You need to run the installation from an account with Administrator 
privileges. Under Windows 2000 or Windows XP, you can use the Run As
facility to run the installation as the administrator.

Currently, the Start Menu, Program sub-folder is created under the user
account who installs the program. This means that if you have to logon as
Administrator in order to install, the menu items are installed only under
the Administrator's Start Menu. To make the menu items available under
your normal user account, open Explorer and move the JD Design sub-folder
from the Administrator Start Menu/Programs folder.

Files Installed by Setup
------------------------

Setup copies the following files to a folder named shellext beneath your
Windows system folder:


ConCat.dll	The ConCat Context Menu DLL
ConCat.txt	This file
ConCat.inf	The Setup Information File

For Windows 9x, this is likely to be the Windows\System\ShellExt folder.
For Windows NT, 2000, or XP, this is likely to be WinNT\System32\ShellExt.


Setup will also add relevant registry entries and Start menu items.





-------------------------------------------------------------------------
			How Do You Use ConCat?
-------------------------------------------------------------------------

1. Split
--------

Select the file that you want to split in an Explorer window. Display the
context menu by clicking with the secondary mouse button, or use the
Explorer window's File menu. Choose the "Split File..." menu item to
display the Split dialog box.

Operation of this dialog box is straightforward. The "size" radio buttons
provide you with pre-set file sizes for common floppy disk sizes, and the
option of a custom size setting.

The destination name shows the range of file names that you will get from
the split operation. You can change the file name (and path) for the
destination files if you use the Change button.

To perform the split operation, press the "Split File" button.

Note: the split operation is non-destructive; it will not delete your
original file.

Operation is fast (depending only on the size of file you are splitting).

2. Concatenate
--------------

Copy the individual files that you have previously split into a folder on 
your hard disk.

Select the files that you want to concatenate in an Explorer window.
Display the context menu by clicking with the secondary mouse button, or
use the Explorer window's File menu. Choose the "Concatenate Files..."
menu item to display the Concatenate dialog box.

Important: The selected order of the files in the Explorer window
determines the order that the files are copied. The first file is always
the one with the focus (dotted rectangle). Here is how you can ensure that
you get the files copied in the correct order:

i.   Select the first file.

ii.  Hold down the shift key and click the last file that you want.

iii. Release the shift key and right click on the first selected item to
     bring up the context menu.

iv.  Choose the "Concatenate Files..." item to display the Concatenate
     Files dialog box.

v.   The order that the files appear in the "Copy" list box, is the order
     that they will be concatenated. Ensure that this is the order that
     you want.

In an unregistered version, the default destination file name is the same
as the first selected file. If you want to alter this, change the "To"
file name before you press the OK button.

When you receive your registration information, enter your registered name
and number into the About dialog box. You can access this dialog from the
Start menu shortcut, or from the ConCat dialog About button.

You must enter the information exactly as it appears. The case, spaces,
and punctuation of the name are significant, and the number is composed of
the characters 0-9, A-F and again, the case of the letters is significant.
If you register the set of utilities, be sure to use the correct
registration number for each product.

You can check that registration has worked by re-displaying the About box
from the main dialog. When the product is successfully registered your
registration name is displayed in the About dialog rather than the entry
fields.


Updates
-------

Any updates to the current version are free to registered users by
downloading the latest version from our web site. Your current
registration number will continue to work with updates.

See the FAQ on our web site for answers to common problems.

Additional Features for Registered Users
-----------------------------------------

1. The ConCat dialog box has the ability to re-order the files you want to 
   join, making it unimportant to select the files in the correct order in 
   the first place. Select the file in the Copy list box and use the up 
   and down buttons as required. The buttons respond to the keyboard 
   accelerators Alt+U & Alt+D.

2. Automatically selects the correct destination filename for files that 
   are split and retain their Split/ConCat naming convention.

3. The ability to automatically create a batch file that will rejoin the 
   files easily on any MS-DOS compatible system that does not have 
   Split/ConCat installed.

4. The last split size is saved between uses.


Removal
-------

Note: Because the Windows INF de-installer cannot currently delete files 
that are loaded in memory, we recommend that you first reboot your 
machine. Then, remove the component without first using it. This will 
ensure that the files are correctly deleted.

Use the Control Panel, Add/Remove Programs item. Select the ConCat item 
(listed as "Concatenate Context Menu Extension (Remove Only)") and click 
the Add/Remove button.

Revision History
----------------

V3.3.2.0  4 Oct 2001
--------------------
Fixed a bug that caused a crash if low disk space occurred when concatenating
files.
Modified the ConCat list display to ensure that the right hand side is
normally visible since the numerical file extension is the most relevant part
of the name to see. Similar for the display of the current file name that's
being concatenated.
In a registered version, the ConCat list is now automatically sorted.
Enhanced the code used in a registered version to remove the digits to form
the original file name.

V3.3.1.0  16 Sept 2001
----------------------
Changes to the concatenate dialog to display the file part number, and to just
show the filename (rather than the full path) in the progress section.
The concatenate file overwrite prompt now displays the file name.
Correction to support numerical output of file sizes in locales that use Indic
grouping of numbers (e.g. 12,34,45,789).

V3.3.0.0  25 Nov 2000
----------------------
Added progress displays to the dialogs to give feedback when manipulating
large files.
Added support for files greater than 4GB. Note that only Windows NT (and
Window 2000) supports files greater 4GB.

V3.2.1.1  15 Sept 2000
----------------------
The file names in the copy batch file now have surrounding quotes to work
with file names that have spaces in them.
Added the option to overwrite any existing files in the split operation.

V3.2.1.0  25 May 2000
---------------------
Fixed a 2GB problem in the split dialog operation. Files > 2GB can now be
split and rejoined correctly.

----------------------
Registered version saves the last used split size.
Display the original file size value in regional number format.
Disabled the Change button for the batch file creation in an unregistered

Modified the About dialog. Changed the registration number field to make
it a little easier to enter the number. Updated the home page URL and
added a mail link.

V3.1.4.0  11 July 1999
----------------------
Modified file handling (yet again). The previous method had problems
splitting files > 800 MB under Windows 9x, and even Windows NT could not
cater for manipulating files where the total size approached 2GB. This
version can now split and join very large files under both Windows 9x
and NT.

V3.1.3.0   3 July 1999
----------------------
Modified to handle very large files.

V3.1.2.1   30 January 1999
