IPA currently does not have a method to zip files. Many of our custom IPA flows export and import large data files and being able to zip them would be greatly beneficial for saving space on our external systems. We would recommend adding 2 Execution Modes in the FileAccess node - One for Zipping and one for unzipping.
If you think this would be beneficial for your flows as well, please consider endorsing our Enhancement Request:
