What MT manager can do with root access,

• As your experience on root if we modified a system part that most important your phone will automatically be rebooted before completing the process. But MT manager will help you to complete the process without auto rebooting.
• Also, it has a greater searching function that supports searching files easily on whole over the root partition of your phone. This is the very awesome function that I found with MT manager.
• Permission manager – It will help you to change the file folder permissions of your root partition.
• System and sdcard R/W access enabler with root
• Other than these special functions and features it has so many other options that come with normal root file manager applications.
