In this video I show you exactly how to zip (compress) and unzip files on a Samsung Galaxy, using the built-in My Files app. Zipping a file basically compresses it, which is super handy if you’re trying to save storage space or you need to send a smaller file to someone. I keep it simple and step-by-step so you can follow along on any Galaxy device. First, I open My Files, go into Internal storage, and locate the file (or multiple files) I want to compress. Then I long-press to select it, tap the three dots “More” button in the bottom right, and choose Compress. You can rename the zip if you want, then tap Compress and it creates the .zip file right there in the same folder as the original. I also show you how to unzip: just open the zipped file, tap Extract, confirm Extract again, and your files are unzipped. That’s it—quick, built-in, and no extra apps needed.
