formatting external drive multiplatform compatible filesystem from macOS High Sierra I have a 160GB external hard drive connected via USB I pulled it from a windows pc to MacBook running MacOS High Sierra, I want to format the hard drive to a file system that should work with Windows, MacOS and Linux operating system.

The hard drive is currently NTFS formatted, into 3 partition which I want to get rid of and just keep single partition.

I am just going to backup my media , doc, zips and tars 

Any Help will be greatly appreciated.
Are there any data on the 160GB external? If yes back them up.
Then format the drive in Exfat.
