I am fuming out the ears, and I humbly suggest people avoid Paragon NTFS altogether. I have lost several important banking/tax files from my NTFS drive with Paragon v12. These files vanished, maybe when the drive was checked by Windows 8 or 10, but bottom line, important files created under Mavericks and Yosemite on my NTFS secondary drive via Paragon NTFS vanished. That was bad enough.
Then the company replied to my plea for help with the following dismissive note:
Thank you for contacting us! Please specify how our drive could affect deleting files. It only gives you read\write access to NTFS volumes from MAC.

Oh, I see. All they do is convert file systems, so how could they possibly make mistakes? Well, I had tried their HFS for Windows, and THAT was outright unusable.
Then they informed me (surprise) that they could not reproduce my problem and stopped writing me.
When version 14 came out, since I'd purchased 3 licenses, their robots invited me to download the new version 14, compatible (also) with El Capitan. I figured it was worth a try. I downloaded, and got 3 new serial numbers.
This gets good. There is no way to register the software to get it out of eval mode, because it says my GUID belongs to someone else, is already assigned to another system. They are computing the Globally Unique IDentifier of my system and finding it matches someone else's. So they won't accept the serial number they assigned me. The absurdity of it is, think about it, I suppose they legitimately may not want me to run it on several different computers (though I have 3 licenses), but what could it possibly matter if I run it on the same one elsewhere or on a mac with a duplicate GUID??? It's just a misguided security concern. Like not allowing you to start your Volkswagen because someone else has one with the same color and options. So? And every time I tried, I had to re-enter my e-mail, and the serial number from scratch, and I WAS starting to get very angry.
But WAIT! It gets better. Running in Eval mode works for 9 more days, I was waiting for them to contact me, having fixed the GUID calculation on their web site. Not yet. So I was copying gigabyte folders from my NTFS drive to my HFS+ drive with Paragon disabled, read-only mode, as part of my getting away from Paragon. No more NTFS sadly, not worth the problems. And I found that the post-copy file count was OK, but the size was lower on the HFS drive. I figured it was maybe more efficient?
But then my applications were falling apart and I discovered that a number of files were zero bytes in size. What could be happening? I wasted most of the day in Terminal mode, looking for ANYTHING that would explain it. I had e.g. some source folders with twenty some files, and half of them would end up copied as zero length, whether copied from the Finder or Terminal commands. Then I found that if I copied them to an intermediate drive first, sometimes it solved it, but not always. Then I rebooted again and apparently only then did Paragon get totally disabled. And at that point (with no more Paragon) all the copy problems went away.
I think this might be how I lost the other files, if the zero length files got plowed under as part of a disk test? In any case this is an honest account of why I am fuming out the ears. Folks, save your files and sanity, save yourself some grief. This software is buggy and destructive, it's all tragic, they can't even do a serial number registration right. They just can't or don't care.
Most people are OK with exFAT, but some issues have been reported under OsX. I forget the details.
