I think you can just upload your files using the upload option that you get when you create a new post. When you want to create a new post, you get an option to also upload any files in WordPress 2. You can give your file a name and title, also add some description.
Generally the file is uploaded in some folder like this:
https://yourdomainname.com/uploads/2007/02/filename.ext. Here, 02 is the month, 2007 is the year. You can provide your visitors with a link to download the file.
