Astro Android App is a File Manager for the Android OS. It allows you to manage files on your phone without the need for a computer. Operations you can perform: copy, paste, move, delete, open with other apps, create and folders, etc. What’s convenient about Astro File Manager is the ability to select multiple files to perform actions. Another convenient feature is the ability to Search for files. The app also provides details on Android apps such as package name, version, file size, and even app activities.
ASTRO File Manager Android App features the ability to backup Android Apps to SD card… a band-aid for the loud public cry from Android users who want to free up low internal phone memory without Rooting the phone. This means you can backup the installer files (APK) on your SD Card, then you can uninstall the app. Thus freeing up space but removing the app. To reuse the app, you will have to reinstall the app from the backup.
