With support for all versions of the Windows NTFS file system, even Windows 8 and 8.1, you'll have no problem working with any Windows machine. Paragon NTFS for Mac gives you full read/write access to NTFS partitions with the same speed and finesse that you're used to under HFS+! With Paragon NTFS for Mac, you'll be able to instantly access and modify any and all Windows files and folders from your Mac. You can read data on an NTFS partition, but that's about it. Macs are wonderful, but here's the thing - when you have that occasion to have to create, delete, or modify files and folder on Windows NTFS partitions, you can't! It's true - the NTFS format, which is the primary file system of any Windows machine, is pretty much locked off from Macs.
