FTP allternitive for file sharing?

I have been using FTP (with FileZilla as my server) to share family pixs and videos, work stuff ect.. for a long time now. I have been wondering if there is a better way to share files? FTP is hard for non-tech people to use, they don't get you need a FTP:// and not an http://, you need a FTP client to get the full potential of FTP, stuff like that) and FTP security by it's self sucks. I have tried FileZilla's secure FTP but you need a FTP client to access anything, and I would like to just use a browser for the non-techy people.

So at the moment I am looking at HTTPS, I have server 2008 with IIS installed and setup for directory browsing. I am not of website maker so I am trying to stay basic, as far as interfaces go. I am using windows Authentication, So i just type my windows user name a password in and I am in. It is all up and running but I have one problem
Permission work the same as in windows, If they don't have access to a file they can't access the file. But is there a way to hide the file if they don't have permissions to see the file? Because it still shows up in the list of directories they just can't access it, It just looks kinda stupid for work clients to see a Family videos folder or Game mods in the list or directories. Where in FileZilla I make my own home directory for each users, is there a way to do that here?
Also is there an easy way to upload files to the web server? (It isn't necessary it is just nice to have that option)

I also stumbled across webdav, would that be more of what I am looking for? Haven't even looked at it yet just wondering.

Any suggestions please throw them out there

Thanks
