How to Unzip a file on Andriod: Every Android tablet comes with a file manager app, but they're typically barebones and can't open ZIP files. Thankfully, several apps on the Google Play Store can do it for free. The one we recommend is "Files by Google." Download Files by Google from the Google Play Store on your Android device. Open the app and locate the ZIP file you would like to open. Look for a "Downloads" folder if you downloaded the compressed file. Select the file to bring up the Extracting dialog. Tap the "Extract" button to open the file. (see attached picture named android help 1)  You'll see a progress bar, and then the dialog will tell you the file has been unzipped. Tap "Done" to finish. If you'd like to discard the ZIP file, you can check the "Delete ZIP File" box while closing the pop-up menu. (see attached picture named android help 2)  That's it! The extracted contents from the ZIP file will be placed in the same folder location as the ZIP file itself.   How to Unzip a file on iOS: You can easily unzip and uncompress zip archives directly from the Files app on iPhone and iPad. Open the Files app on iPhone or iPad Navigate to the Zip file you want to open and unzip Tap and hold on the zip archive file name, then choose “Uncompress” from the options in the pop-up menu Wait a moment for the unzipped file contents to appear in the same folder in Files app as the original zip archive Repeat with other zip files you wish to unzip if necessary Small zip files will unzip and uncompress basically instantly in Files app. For large zip files, it may take a moment or two before the zip archive has uncompressed all contents.
