Supported file extensions

All files that are uploaded in Openlearning needs to adhere to a mime type and extension whitelist which excludes any executable file types (binaries, scripts, etc.) which could execute malware when downloaded and executed on a user’s computer.

This affects uploads that are done through any of our widgets within the platform, including Text Widget, File Widget, HTML (xAPI) widget, Video widgets.

Here are the current file extensions that are whitelisted in our platform that will be updated accordingly whenever a new file extension is added to the list:
