OI File Manager is an ad-free and open source file manager. It is one of the most popular app in its genre. While OI File Manager may not be the most powerful tool for advanced users who expect root functions, it still offers all the basic functions that you would need from a file manager.
And the best part of course is you don’t need to be rooted to install this on your device. OI file manager can also be used as a file-browser within different apps such as Gmail, KeePassDroid.
Improvements in Recent update
New Light theme and Bookmark button
In addition to some bug fixes, they have improved the user interface to a more Holistic theme. The bookmark button will help in navigating to your favorite folders much faster.
Multiple selection of files and action bar
They have also enabled multiple selection of files, which you can do by long-pressing on any file or folder and then tapping normally on the other files which you want to select.
Selecting a file or folder brings up the action bar which can be accessed by tapping the on-screen menu button on the top right.
Note: The action bar supports devices Android 3.0 and greater.
Search (including Voice) – Best feature in the update
Missing Dark Theme
One thing that I miss is the dark theme from the older version. But that shouldn’t stop you from installing this app on your phone.
Grab it and install from Google Play
