How To Split A Large File Into Several Small Files Using WinRar And HJSplit And How To Merge Them Back

If you ever wanted to upload and share a 350 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.

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:
