1 Using Your Built-In File Manager
Most Android phones (Samsung, Google Pixel, etc.) can do this natively.
Open your file manager app
On Samsung, it's called "My Files." On Google Pixel, it's "Files." Other brands may call it "File Manager" or "Files." Find it in your app drawer.
Navigate to the ZIP file
Usually in the Downloads folder. Tap "Internal storage" → "Download" (or check your recent files).
Tap the ZIP file
Your file manager will show the contents. Tap "Extract" or "Extract All." Choose a destination (or use the default) and tap OK.
Enter password if prompted
If the ZIP is encrypted, you'll be asked for the password. Type or paste it and tap OK.
2 Using ZArchiver (Free App)
Best free option if your built-in file manager can't handle it.
ZArchiver is the most popular and trusted archive app on Android. It handles ZIP, RAR, 7z, TAR, GZ, and dozens of other formats — all for free with no ads.
Install ZArchiver from Google Play
Search "ZArchiver" in the Play Store. It's free.
Open ZArchiver and navigate to your file
Browse to your Downloads folder (or wherever the archive is saved).
Tap the archive file
Choose "Extract here", "Extract to ./", or "Extract to [folder name]".
Enter password if needed
Type the password and tap OK. Your files will be extracted.
