My Articulate 360 Storyline file simply disappeared

Hello Shannon, 

I'm really sorry to hear about your project files. As mentioned in my previous response, Storyline 360 doesn't have the capability to search for any existing project files and delete them. The only time Storyline 360 will delete files is when it is publishing to an existing folder. 

For example, in the screenshot below, if you publish a course to the folder 'test', everything inside the folder will be deleted first before the new course files are published. 

This will however, not delete any other file outside the test folder. In the scenario that you reported, there isn't a way for Storyline 360 to delete all existing files in your local drive, and access your network drive to delete the files there as well. There's a high probability that the files may have been moved or deleted by something else. 

Please reach out to your IT staff to see if the files may have been quarantined by your organization's anti-malware applications. Feel free to open a case with our support team here if you need further assistance in identifying what happened to your files.
