The "Clone" feature is used to create an exact copy of a hard disk or partition, including its layout and content, allowing for identical backups or replacements.
The method of deleting a disk partition is a way to remove unwanted partitions, turning them into unallocated space.
Formatting a drive partition allows you to change the file system, resolve some corruption issues, and sometimes eliminate viruses and malware by altering the drive's format.
Allocating space can be useful when one drive partition has too much free space, while another partition has inadequate space, allowing you to redistribute the excess space to the partition that needs it.
The "Migrate OS" feature allows for the easy transfer of a Windows installation drive to another without requiring a reinstall.
Qiling Partition Master customers are increasingly converting between GPT and MBR, as well as between NTFS and FAT32, and from Basic to Dynamic, taking advantage of the benefits of these conversions.
