How often do you have to use "Synchronize Library"?

To get an idea on the best way to  make synchronizing easier, i'd like to know how often you need to do it.
Would be nice, if you'd tell me when you have to do it.

I think its not a regular thing-you might not do it for a while then have a spate of doing it if you see what I mean.

Doing it is a pain, I forget half the time-should be automatic!!

It's not really time driven. I sync whenever I install a new product or reorganise my runtime folders.  Auto-sync would be nice, but would probably slow down the program.

Every day - but then I download a lot Poser content and also move content around.  It's no real problem I usually spot items missing quite quickly when I forget to sync.
