We've had good success saving our Articulate Studio-related files to shared Dropbox folders to make collaboration easier. We usually keep the files in Dropbox up until it's time to import audio (due to storage issues) -- then we usually pull them onto a local drive to finish up development.
We're considering a move to Google Drive since our institution now supports it. We're wondering if anyone has used Google Drive for storing development files for collaboration? If so, any issues we should be aware of?
