How do you set FTP Folder size restrictions with .htaccess

Is there a way using .htaccess (or any other method really) in which you can restrict the file size of folders on an FTP / Web Server?

I want staff to be able to use some FTP space for storage but wish to impose restrictions on the maximum size a folder can get to - preferably per ftp user (or per folder would be good too)

Typically one does this using their FTP server software, what are you using to be your ftp daemon?

FileZilla! Can this just be configured on the folders within that?
I assume the folders would retain those restrictions regardless of who logs into the server and regardless of the FTP client they use as well?
