I created a new folder by mistake and then immediately deleted the folder. The app crashed and now crashes every time I open the application.
Rebooted phone and it still crashes.
I'm not sure "crashes" is the right term to use as the app appears to still be running if I double click the home button.
I open the application, the file list appears momentarily, and then the application disappears.
If I double click to see open applications, it is still there but if I select it, it shows the file list momentarily and then disappears.
I am using dropbox to hold my files.
