I know CUBA.platform has some integration with File Storage currently but it would be great if there was an integration with FileCloud. Their system offer a lot of additional functionality that is not available from what I can see via the current CUBA integrations at least not without some major development on top.
FileCloud provide Online Editing via Office365, Ransomeware protection, Virus scanning, Local Sync apps, multi-tenancy, 2FA, Custom Branding, Web Access, Mobile Apps, API, Supports Cloud Providers like AWS and Azure etc
The features for a commercial custom branded system are amazing for the price. Since there is already some support in CUBA for file handling it might not be a big stretch to support FileCloud.
