Is There Any Way to Create a Partition on the MBR Drive After Windows 10 Installation?

I need to create a partition to keep some files. However, my drive is MBR, and it already has four primary partitions. What can I do? Is there any way to create more partitions after Windows 10 installation?

According to what you said, you want to create a new partition on your MBR drive that already has four primary partitions. As we know, an MBR drive can only hold at most four primary partitions or three primary partitions plus one extended partition. In this case, you need to first convert one of your primary partitions to a logical partition and then create new partitions.
