Last night Cyanogen took to Google+ to announce their new file manager. This file manager is now baked into all future CM10 builds starting with nightly builds that are out now.
“The guiding philosophy behind CyanogenMod 10 is that any feature we add in should be seamless in it’s implementation, intuitive in its usage and functional to a large group of users.”
CyanogenMod has implemented this file manager so that users can have complete access to their device without the need to go to 3rd party applications. This app is open-source so you can go get the source code for the application and play with it yourself.
