🔧 How to Split a ZIP File on Mac

Let’s say you have a big file name file is Documents.zip and you want to split it into parts of 100MB each:

1. Open Terminal

Go to Launchpad > Terminal (or press Cmd + Space and type "Terminal").

2. Navigate to your ZIP file

Use cd to go to the folder where your zip file is:

ex : cd Volumes/SSDM2

3. Split the file

Use the split command like this:

split -b 100m Documents.zip Documents_part_

• -b 100m = size of each part (change 100m to whatever size you need, like 700m, 50m, etc.).

• file.zip = your original zip file name.

• part_ = prefix for the output files (you’ll get files like part_aa, part_ab, etc.)
