Documents Free (Mobile Office Suite) app review

A very basic app for viewing documents and arranging them in folders. Could not really edit any word documents that were downloaded from my mail. Viewer more than editor. Clean page views and easy to use though if basic functionality is what one is looking for. After arranging all my project related documents in folders for offline viewing, I suddenly found that the app stopped working. The app would shut down as soon as I started it. Tried turning off the ipad and restarting the app but didn't work. Updating it on App Store didn't work either. Had to delete and reinstall. Luckily had all documents backs up. Cloud storage is the advantage available with Documents. Works with Dropbox, Skydrive, etc.
