Loading an archive to server

Options
Hello, i'm working on a game based on archive with xml file that contains all the data and file links needed for the game, and the actual files(audio, images and videos) is being parsed by unity and game mode is formed.
I'm wondering if it's possible to load an archive to the server and then download it on clients. (Archive is uploaded by a room creator). It's a zip-file, not related to asset bundles and resources folder. Host chooses it with openfiledialog.
If so, please share any documentation or advice that might come in use. Thanks.
