Need to format hard drive to exFAT

In general, it is necessary to change a hard drive to exFAT file system in Windows 10/8/7 under the cases listed below:

Case 1: “I have got a 1TB external hard drive and it has been formatted with NTFS file system. I want to transfer some files between my PC to my friend’s Mac. But when I tried to put a certain file on the Mac, I failed to copy the file from the external hard drive to the local drive on Mac”.
Case 2: “I have one hard drive used for PS4. When I connected the FAT32 hard drive to a working computer running Windows 10 and tried to copy one large file to it, I was told that the file is too large to copy for the destination file system”.

In Case 1, the hard drive is NTFS file system. It can be fully supported by Windows systems and read-only supported by Mac OS. If you need to make the external hard drive be compatible with Window and Mac, you need to format hard drive to exFAT or FAT32.

In Case 2, the hard drive is formatted with FAT32. The hard drive with FAT32 file system is unable to store large file beyond 4GB. If you insist to move the file to the hard drive, you need to format it to NTFS or exFAT. And because the hard drive is used for PS4 and NTFS is not compatible with PS4, you have to change the file system of the hard drive to exFAT.

All in all, considering compatibility and file size limit, exFAT is the most suitable file system for your hard drive in the two cases above.
