Reply To: Indesign file — CS6 or CC?

Not just printers being reluctant – I’ve customers who currently use versions back to CS3. The only thing I’ve done is put a reminder in each customer folder: an empty folder named ” is CS3″ or whatever, named such that it appears first in the list.
Otherwise, I’ve lost count of the times I’ve opened a file and got a * ahead of the name to denote it’s been opened from an older version, or the reverse, usually a message about missing plugins.
