So far the drivers recognize and will write to NTFS partitions, sort of. They will not batch copy any groups of files but only individual files. When trying to copy more than one file the process stops and a message comes up saying the file name is too long. It would appear that the software is seeing the separate file names as one ridiculously long name. I was trying to copy images off SD cards from several cameras for a project to be processed in both OS X and Windows and write the files to an NTFS formatted drive in Yosemite. The Paragon software managed to corrupt the file structure of one of the cards simply by reading it. The card could be reformatted in both OS X and Windows and in four different cameras and worked properly after Paragon was done with it and worked fine prior to encountering Paragon NTFS 12. For paid software this is pretty sad: no direct support and unreliable performance. At least it sort of works.
