Within my store I currently have about 30 MB of sample movie files within the main store directory...

Backing up the store takes an enormous time with these added files (which never change) so I would like to move them to another location, outside of the store directory and outside the public_html directory on the server. Having them outside the public_html directory would keep them relatively secure. And not having them in my store directory will mean backing up will not take forever...

I would like to know if this is possible, and the basic steps to achieve this.

Thanks in advance!
