We can't tell them how long it will take to 'download' the files but that should be the fast part, since the web server is on the local domain network.  If there was an easy way to see the total for that I'd add a progress bar for that part also.  I'm iterating over the file objects in the zip stream to find the total size to show the progress of writing them to disk which could be slow if they don't have an ssd.  Sure that iteration adds a few seconds but it is fast as long as it can be done in memory.  If you copy a large file(s) in Windows it always starts with 'calculating' total time..
