Locking access to a directory

[Richard]

Hi, anyone know if there's a flashfxp setting to lock directory access on the remote server?

E.g. Sometimes i have more than one version of a site on a domain, in different directories, like this:
/public_html/version1/
/public_html/version2/

What i'd like to be able to do is set up a site connection to version2 that doesn't allow me to navigate back up to public_html, just so i don't accidentally starting writing files to version1 when i'm only working on version2.

I know it's possible to do this somehow in apache settings, but wondered if flashfxp has the ability
