If you ever wanted to upload and share a 650 MB file with your friends using an online file sharing service but
you want to upload the file in smaller chunks. How can you split a big
file into multiple chunks and upload it to the file sharing service?
WinRar and HJSplit are the best applications to not only split big files
in to several chunks but also to compress them while splitting.
Here are two methods to split a large file into several small files:
Method 1: Using WinRar
To start splitting, Right Click on the file that you want to split, choose the option Add to archive.
WinRar automatically assigns a name for the new archive it is going
to create. If you don’t want a default name, you can change it as
appropriate.
Under the option Split to volumes, either
enter the desired maximum size of each file chunk or choose an
appropriate size from the available drop down option. In my case I
entered 5 MB for each chunk of file.
Click Ok and wait for few seconds. WinRar compress the source file and splits it in to several files.
Method 2: Using HJSplit
To start splitting the file using HJSplit, Click on the Split tab on the main window .
Now provide HJSplit with your Input(Locate to your file which you want to split) and Output(Locate to where you want your split files to be placed) destinations and enter the desired maximum size of each chunk of file.
Now click the start button and wait for a while till the file splits into smaller chunks.
How To Merge/ Join Files Using HJSplit
With HJSplit you can not only split files, but also join the split
parts back together again. To start Joining you files, follow these
simple steps.
After clicking on the ‘Join’ button in the main HJSplit screen, you will see the following screen:
Make sure the set of split parts (set of files ending in .001, .002,
.003, etc.) to be joined all reside inside the same directory. Click on
the button ‘Input file’, in the screen directly above, which will open the dialog shown directly below:
Note that only the first file in the set of split parts (the .001 file) is visible
in this dialog. Note that it is important that all split parts are in
the same folder. When the other files which belong to the set of split
parts (.002, .003, .004, etc.) are in the same folder, HJSplit will
automatically find them during joining.
After pressing Open, the name and path of the file you just selected will appear in the input file box, please see below:
Now press the Start button to merge all the files into one file.
