Permanent access to WorkDocs for external parties

Hi, I want to create a permanent link with acess to a WorkDocs folder to anyone (inc. external parties : selling partners/vendors) who has the link. They don't need any write permissions, just to download an Excel file we will share with them. Is WorkDocs the best tool to do that?

Reason we are not using other tools e.g. media central is because the file is undergoing updates, and we want the latest version to be always be accessed via one single link. Alternative would be to create a link with access to a specific file (instead of a folder) as long as we can keep updating that file

Thanks
