Labels VS Dircetories...
Is this storing-in-directory solution outdated?
When I first saw this label thing in Google's mail I found it strange.
Now I start to think it is better. Why do we need directories? There can be queries for all the keywords=labels.
I know that in PP I can put photos in several directories. But this increases disk usage (am I right?), so labels seem to me more elegant.
Does the speed matter? Let's say I have a site with nice traffic and 5 million photos all in one single directory. Would the server be faster if these were in 5 or 10 or 100 directories?
