As storage and file sizes have been increasing, the storage limits on CD and DVD media has not. HJSplit, a free software utility, allows you to quickly and easily split large files into two or more parts for burning to a CD or DVD. Another great use for HJSplit is to split up a large file in two or more parts prior to emailing it as an attachment that may get rejected due to email size limits. Further, HJSplit runs on Windows, Linux, and Mac so if you split a large file in Linux, it can be re-joined on a Windows machine and vise-versa.

If you are using a Windows system, HJSplit is a very small application and does not need to be installed. Simply download the Windows version from here, save the file to your desktop, and extract the file. Typically, you can extract the file by right-clicking on it and choose Extract All…Once the file is extracted, double-click HJSplit.exe and you will see this screen. (pic below)

Split A File

1. Click on the Split button to bring up the File Split window. (pic below)
   
2. Click on Input File and choose the file that you want to split. In the above example my file, largefile.bak, is 17MB and is located in my c:\large file folder. Next, choose your output folder. I chose my folder called c:\hjsplit_output, and have selected to split the file into 1MB parts.
3. Click Start and your file is split into parts as per the above selections and your output folder should look like the example below. Now, you can email, burn, or do as you please with the split files. Note, when burning your split files for backup, I would include the HJSplit.exe file you used to split the files on the CD or DVD.

Joining The Split Files

1. From the main HJSplit screen, click on Join to launch the File Join window. (pic below)
   
2. Click on the Input File button and choose the file ending with 001 of your split file set as per the above example. Your Output folder will automatically default to the same folder as your source split files which is fine for most users. Simply click Start and when the joining process is complete, you should see your file joined back together in output folder. The joined file is now ready to use. (pic below)
