Thread:Project:Support desk/Linking to an Excel Document

I need to link to an Excel document from a wiki page. I'm not trying to embed the content in a table - only to have view access to a an external excel file. Given that I can only upload image files (and not excel files) - 1. Where do I put the file? 2. How do I reference it such that others can view it from a link? I've seen where people put files in dropbox but it doesn't seem to work for excel files. I'm open to installing an extension on the server but I can't seem to figure out what extension I'd need. Thank you!
