Introduction

This is a simple but useful utility developed using C# which runs under Microsoft .NET Framework v2.0 or higher. This tool helps in splitting huge files into many small parts and merge them at any time and use it. This is a technique of separating the file bytes into a specified size.

Using the demo

To use the demo application, open "SplitFile.exe" from the demo link above. Click File --> New Project, and then save the project at any location at your wish. This project file can be used to resume the splitting process in future, if interrupted in between. Then, click the Browse button to select the source file (the huge file which has to be split). Now, a new panel will be visible at the bottom which shows the total size of the source file in bytes, and the remaining size indicates the remaining size to be split, which is updated after adding or removing each file.

In the above window, click on the Browse button to add the part name and location. And then, enter the size of the new part, and then click Add Part button so that the part will be added to the list and the remaining size will be updated. Do this step continuously till the remaining size is 0. Increase the buffer size to increase the speed of the process. Then, click on the Start button to start splitting the file. This process does not damage the source file.

Note: Select the checkbox Create Merge file to Join parts to create a batch file to merge the split parts. The batch file will be created at the same location as that of the project file, containing the name of the project file as prefix. While merging the file using "Merger.bat", all the parts and the batch file must be placed in the same folder.

Using the source code

The description of the source is given line by line wherever necessary as comments.

Points of interest

This tool can be used to split any types of file (e.g., video, audio, graphics, images, executables [*.exe], text files, etc.).

The process can be stopped at any time, and can be resumed whenever needed.

To resume the stopped process in future, just drag and drop the project file to the icon at the desktop, or open the application, click File --> Open Project, and then select the project file (*.sp), and click the Start button.

While the splitting process is running, the Close button will not exit the application; instead, it will be minimized to the tray so that accidentally exiting the application will be avoided.

When you resume the project in future, if the source file has been moved or changed, then the application will prompt to select the old source file so that the parts will always be the same as that of the source file.
