Acessing /static via FTP etc. - is it safe?

Hello,

I would like to put some static html files into my antville installation - I cannot get some special cgi/perl-things to work in stories etc.

My question is: is manually putting static files (html, jpg etc) in the static folders safe (via ftp, or copying them at the command prompt)? Or does the antville-database get corrupted then?

Thanks!
