At times you may have to split a large file into several smaller pieces. For example, you may want to split a large file into 700MB sections that will fit on CD's, or split a 50MB file into 10MB chunks so you can email them.

In this tutorial we will show you how to split a file into separate pieces using the 7-Zip archive program.

You will need 7-Zip installed for this tutorial, it is a free open sourced archiving software that is available online, and can be downloaded here.

Since the split files will be created in the same folder your original file is in, I recommend creating a new folder and putting the file you are splitting in it.

Splitting a File:

  1. Right click the file you want to split, then roll your mouse over the 7-Zip, then click Add to archive. In my tests I am splitting a testfile.exe that is 625MB.
    selecting 7-zip
  2. The Add to Archive menu will come up, in the Archive format section click the drop-down box and select zip. Then in the Split to volumes, bytes section, enter or choose a size from the drop down menu. In my tests I am entering 20M for 20MB. You can also change the name in the Archive: section, be sure to keep the .zip extension at the end of the file name.
    editing settings for splitting file in 7-zip
  3. Click the OK button. You will see a progress window displaying the status. This will take some time, depending on the size of the file.
    compress the file in 7-zip
    After this completes, you will see the separate files in the same location as the original file.

    Congratulations, now you know how to split a file in to separate pieces using 7-Zip!
