Research NTFS and you'll discover the current Mac can read and write NTFS. The old advice was to use FAT32 but I found it too fragile and the 4GB file size limit to cause people pain.
We currently are running out of space on our desktop computer. It is mostly because of pictures, short videos and music. I would like to get an external harddrive to solve this issue. We are also considering switching to a mac laptop and getting rid of the pc. Are there any external drives that I can use with both computers? Is this a possible way to transfer files between a pc and a mac?
