OI File Manager

The OpenIntents file manager allows you to browse your SD card, create
directories, rename, move, and delete files. It also acts as an extension to
other applications to display "Open" and "Save" dialogs.

Note that this is included in older versions of Cyanogenmod as a system
application, so you will not be able to upgrade it without first manually
removing (as root) the existing version.

Features:

• Show list of files with thumbnails for images.
• Move, copy, rename, and delete files.
• Create and delete directories (folders).
• Send files by email.
• Acts as an extension to other applications, like GMail, to attach files.
• Support for many file endings and mime types.
• Supports PICK_FILE and PICK_DIRECTORY intents so that other applications can use OI File Manager.
