If you own a PC as well as a Mac, chances are high that you often transfer files between these computers. While there are plenty of ways, including many online services and third-party tools, to share files between Windows and Mac OS X, transferring files between these computers using a flash drive isn’t as easy as it sounds. The problem is that Mac OS X can’t write to NTFS partition by default. In order to copy some files to a NTFS formatted USB drive you need to either format the drive in FAT file system or install third-party applications. Similarly, Windows can’t write to Mac’s HFS+ partition with default settings and in order to do so you need to install HFS+ drivers. At times, you might want to convert a HFS+ partition to NTFS on your Windows machine.
