How can I add msftdata flag to an ext4 partition?

Question

I have moved my partitions around to make room for dualboot, and now Windows 10 is on sda1 and sd2, with my linux install on sda3 (boot) and sda4 (home). I would like to access sda4 from my Windows install and am attempting to use Ex2Fsd in Windows. From what I understand, in order for this to work in Win10 I need to add the msftdata flag to my existing partition. I assumed I could do this in gparted, but there is no option for that. I installed gdisk, but don't know what commands to issue. I have a good backup of my partition.

Answer 1

Solution as follows:

1-run Gdisk from CLI 2-select disk (in my case it was /dev/sda) 3-select partition (in my case 4) 4-select "t" to change a partitions "type" code 5-enter "0700"
