We've been following Enterproid since they first debuted their Divide app for Android at CTIA in October. So when we heard the company was announcing major additions to the software here at Mobile World Congress we made sure to stop by their booth to take a look. As a quick refresher, Enterproid's Divide app is one of a growing number of Android-based software solutions geared toward separating a user's personal and work files on their smartphone or tablet.

Divide Extensions ups the ante with Divide Files and a new calling feature. Divide Files provides users with a way to access their sensitive work files on their phone, email them and edit them without them ever touching the phone's memory. Instead, all files saved in Divide Files is stored in the cloud, or more accurately, on your employer's servers. During our time with the new software we explored the Divide File system and even prepared an email with a file attachment that we pulled from Divide Files.

The feature is the answer to one of the biggest problems employers face as they allow employees to use their own devices on the job, which is the possibility that a smartphone with sensitive files will go missing, be stolen or an employee will leave their position with a company and keep the files for their own gain. With such files saved on a secure server however, employers can rest a little easier.

Also introduced with Divide Extensions is a new dialer system. The feature allows users to place phone calls from the Divide side of their phone and choose whether they want the call to originate from their smartphone or from their office phone. The system essentially extends your office phone's call management settings to your smartphone, ensuring that your privacy is protected.

When we called a number and chose for the call to originate from a nearby desk phone, the called I.D. for the phone we dialed displayed the number for the desk phone. We were also able to place a call on the demo smartphone and push it to the office phone, a nice addition for when you need to make a call on your way into the office. You can also send calls back from your office phone to your cell phone so you don't have to hang up on someone when you leave the office.
