How to upload files to a windows server?

Question

FTP

Good afternoon
There is a computer running Windows 2008 Server, and there is a need to give different users the ability to upload files to it.
Conditions:
- users should not have access to already uploaded files and preferably should not see them.
- it should be easy for the user (preferably without additional software on the user's side)
- the files that are supposed to be uploaded are perfectly compressed (from 1 gigabyte to 200 megabytes), so it would not be bad to compress them during transfer. Maybe gzip?
- It is advisable to write some comment when uploading a file and save it along with the file
- you need to somehow handle the user's attempt to upload a file with a name that is already on the server.
- authenticate users by login/password (not necessary if the first point is satisfied)
My options:
1 - Teach users to archive the file, write comments in its name and upload it to FTP via browser.
Cons:
- When entering FTP, the user sees all the files that were uploaded before him
- You either need to explain a lot to the user or write a script that will compress, rename and download for him and force him to download this program
2 - Find / write a web service that could be was deployed on the server. Here, in principle, I see that I can implement almost everything in Python, it’s not clear only with compression: does gzip work when uploaded to the server? Is it possible to reap a gig file on the client using Javascript?
Maybe there is already a similar script
