Format for Destination disk

A bit of a simple question. What is the required format for the destination disk with Winclone 6 ?. I am getting a read only error trying to save to disk formatted in NTFS. My Mac is a MacBook Pro mid 2015

If you are restoring an image, it needs to be MS-DOS (FAT) or NTFS. If you are saving an image file, it should be APFS or HFS+.
