File type configurations

Hi all, i have 2 questions on file management/configurations.

  1. We create android apps for clients and upload .apk files to our OC instance for clients to download/test. But we're seeing that .apk file types are not initiating downloads on mobile browsers. Is there a configuration that needs to be made so that the server/OC recognizes this file type and initiates the download as any other file?

  2. Is there a way to restrict certain file types from being uploaded to OC? For example, i would like to prevent uploads of .exe files. Possible?

Thanks

Hi,

there is either this app:

or the Files Firewall feature in the Enterprise Edition:
