Is it possible to directly download a file from on-prem self-service ?

We have a self-service portal with many apps and procedures that users can run.
Our self service portal web URL is https://kaseyaselfservice.ourcompany.com  (not literally "ourcompany.com")

Is it possible to use a hyperlink along the lines of https://kaseyaselfservice.ourcompany.com/directlinkto.file   ?

If so, what would be the URL path to those files?
