Copy without resizing partitions: It will not resize the partition size.
Add unused space to all partitions: It will reallocate the unallocated space to each partition of the target disk, appropriate for the disk size.
Manually adjust partition size: It allows you to extend unallocated space to any partition on the destination disk as you want.
Convert the destination disk from MBR (GPT) to GPT (MBR): It helps to convert the partition style of the destination disk if it is different from that of the source disk.

✍ If a GPT disk has more than 4 primary partitions and you want to copy from GPT to MBR disk, make sure you check "Convert the destination disk from MBR to GPT". Otherwise, Qiling Disk Master will only copy up to 3 partitions due to partition style limitations.

✍Sector by sector clone: by checking this option, Qiling Disk Master will copy every sector from the source to the target, whether it is used or not. It requires the target disk to be equal to or larger than the source disk.

✍Qiling Disk Master is also operating system cloning software which allows you to copy only OS to Samsung SSD.
