Why is Yosemite limiting file names to 31 characters?

When I attempt to save a file now, I get an error message saying the number of characters has exceeded the limit of 31 characters. What? That's never been true in an Apple OS. I restarted, ran Disk Permissions and Disk Repair. Same issue. What's going on?

MacBook Pro (15-inch Mid 2012), OS X Yosemite (10.10.1), 16 GB Ram; 480 GB SSD

Yes! Today again the error message. While saving an attached .doc in Mail under a slightly other filename as received.


Since the error message is (translated from Dutch) "Names with more than 31 characters are not supported by the target volume", I immediately tried to save it to a traditional drive. To the backup drive in my MacPro. (My standard volume is a 2011 Kingston SSD (SVP100S2512G Media). The saving to the rotational drive worked, no problem :-)


So maybe it has to do with the SSD.

The bad news: I couldn't reproduce the error message.

Today another error message. File doesn't exist.

Situation: Copied part of a text in mail to an empty TextEdit document and tried to save the TextEdit file with a specific filename to my main HD (SSD). Error message in Dutch. Translated: "The document 'Untitled' can not be saved as '201503xx-SMS dialoog.rtf'. The file doesn't exist".


Could repeat this procedure 3 times.

Then saving to my old-fashioned rotating HD: No problem.
