KSplitter Application

 
I wrote the very first version of this application on February 12, 2003. On this page you will find complete details about this application i.e., what is its function, how does it do its job, version history, troubleshooting and known issues etc. At the end of the page I have also provided two download links from where you can download the application as well as the help file. Since this application is a freeware (but not open source) you are free to distribute it to your nears and dears without worrying about the licensing issues. But at the same time you are also hereby being warned that no reverse-engineering tool should be used to decompile (disassemble) the binary provided from this website in any manner (its a punishable crime). At the time of writing, the latest version was v6.0.1.



Anatomy !!

KSplitter splits up a large source file in to N pieces (where N may be arbitrary or chosen by you) and creates a Batch file, which can re-assemble the source file on the destination. The source file, which is splitted, can be of any kind (as long as the test conditions say) ranging from a simple MS Word document, covering HTML files to rather complex MP3, MPEG, EXE and ZIP files. Virtually any file can be splitted by KSplitter.

The purpose of splitting a large file into smaller pieces is to accommodate them on to different floppies and/or other media individually. This is especially useful in some cases. Let us consider a typical one:

Problem: I have a file on machine A named file1.exe, the size of which is 4 MB. Now you want to transfer this file to a machine B. The condition is that machine B neither has a CD drive nor a network connection. Besides this only removable drive available, on B is floppy. How will you make the transfer?

Solution: Split up the file1.exe in to three smaller pieces, having a file size of 1.25 MB each. Now copy these files (file1…1, file2…2 etc.) along with the Batch file (created by KSplitter only, during the split process) on to the different floppies. Carry and copy these files on to the machine B, in a folder. Finally run the Batch file, contained in the folder by double clicking on it. The file1.exe will again be re-assembled on the machine B.

The same logic can be applied on to any media other than floppy (for instance, you can use multiple CDs to copy a large movie’s DVD contents). Besides this you can make the split file and the batch file, available on to your Website on the Internet. So your users will be able to download a split at a time and later they can re-assemble them all by using the single batch file, to create the final application on their machines.


How It Does?



KSplitter splits up a source file in one of the following two ways:

1. Mode-1: By offering you to select the split size (size of each split file).
2. Mode-2: By offering you to select number of split files required.

Either way you choose, the KSplitter does the rest job automatically. However, there is one restriction in the mode-1 i.e., the size of the split can’t be less than 1.25 MB. This restriction was imposed, because for the optimum (not yet fully optimum) use of the floppy disk you must place at least 1.25 MB of contents on it. While using mode-1, KSplitter automatically decides – how many split files are to be generated. But, this restriction has not limited the user to split a file in greater-size (greater than 1.25 MB) pieces. You can, by using mode-2, specify the number of split files required. The KSplitter then, does the mathematics automatically to allocate the file size for each split.

Once KSplitter has finished its job, an appropriate message is generated, so as to show the user that the job was done successfully or not (whichever is the case).


Version History & Known Issues

** Extensive help system, with the facility of <F1> was added (requires help file download from the Internet).

v5.0.0
** The program now automatically checks the destination drive for the available free space and if it is not sufficient to hold the entire split, appropriate messages are shown.
** Possiblity of having the split names, similar to the files previously splitted has been removed. (Thanks to Mr. Rick Wallach again, for pointing out the same.)

** Provision made for going to one-level-up in directory hierarchy, with a click of a button.

v4.0.0
** Provision made for specifying the number of split-files besides the split-size.
** The 1.25 MB restriction has been resolved by means of above mentioned feature.
** Tool tip enhanced and other small bugs fixed.
** Disabled manual path typing (since it is error prone). Only selection is possible.
** About dialog box now contains hyperlinks - directly clickable.

v3.0.0
** This version of KSplitter now allows user to specify the chunk size also.
** A bug in drag-n-drop feature was removed.

Know Issues: (Contents of Troubleshoot.txt)


On some machines when you run the KSplitter, you get an error message, such as: "Failed to load control 'CommonDialog' from comdlg32.ocx. Your version of comdlg32.ocx may be outdated. Make sure that you are using the version of the control, that was provided with your application".

Actually this message pops up on your screen, because you are using an older version of Common Dialog Control than the one which application uses. Hence, you need to have Common Dialog Control 6.0, installed on your machine. If you find the above mentioned error (On Windows-95 or Windows-98 machines) you need to follow the steps mentioned below:

1. Unzip all the files contained to a folder on your machine. The files included in archive are:

a) KSplitter.exe
b) Readme.txt
c) License.txt
d) Date.txt
e) Troubleshoot.txt
f) RegisterComDlg.bat
g) Comdlg32.ocx

2. Now double click on the "RegisterComDlg.bat" file.

3. If you face a success-registration-message, such as: "DllRegisterServer in Comdlg32.ocx succeeded.", you have successfully installed (register) the Common Dialog Control 6 on your machine.

4. You will now not receive the above mentioned error and can start working with KSplitter.

Alternatively you can read the "readme.txt" file's Known Issue section for more details.
