I am using OneDrive to store all my photos, documents, some portable software, PowerShell scripts, and many other things.
I was quite happy with it (especially the Smart File features where I can see and manage all my files on my small tablet) until I realized that my files were not synchronized any more. I then opened Task Manager trying to monitor the OneDrive Sync Engine (named SkyDrive.exe) and saw it kept crashing shortly after being launched.
