Re: mkdir error message -- what does this mean?

Hey Aryeh,

You can still retain the files, but you just need to organize them in a
fashion in which the parent (or otherwise) doesn't reach the limit.
I'd suggest the easiest way is organizing them by year or even going a bit
more fine tuned like parent/year/month/day ... or maybe even
parent/archive/year/month ... or .... you get the idea.  There are many
ways to skin this cat.
Regardless of what you decide, you now know there's a limit and can
conceivably determine the best way of fixing it.  ;)

Thanks,
Paul Procacci
