Sliding your finger from right to left opens the options menu where you'll find all the available features: file and task managers, system information, and more. Sliding from left to right opens the help menu, where you can check information related to the tab open at that time.
In the Advanced Tools settings you can activate and deactivate advanced features for root devices. You can also change the look of the app (there are three different themes), and the way the app displays ads (there are two modes).
The list of things you can do with Advanced Tools is really long and varied: create folders, delete files, compress documents in ZIP format, uninstall apps, back up APK files, stop apps from launching at startup, and send files through FTP or Bluetooth. You can also get information about parts of your device, such as the screen, processor, memory, etc.
Advanced Tools is an excellent app for managing Android files and apps and finding out every detail about your device.
