Astro File ManagerCompany: Metago Inc.
A file manager may not seem like the type of application to get excited about, but Astro File Manager does the job so well that it really is a must-have app for your phone.
For example, it makes it much easier to copy or move lots of files around as it allows you to select multiple files at one time. It also has a handy image viewer and can be used to decompress zip and tar files. On top of this, it acts as a task manager letting you kill background tasks so they don’t drain your phone’s battery.
It can even be used to back-up applications. The free version is ad-supported, but for £2.50 you can upgrade to the ad-free pro version.
Astro File Manger is one of the best utilities that you can download for Android phones.
