This is a very simple question. When Baidu Partition Assistant Professional Edition 5.0 is installed on drive C, it must be drive C. Double-click to open the software, and you can see all your partitions, as shown in the figure below, including all hidden partitions. Because you don't want to move the file recovered by one button (if there is one, it is the second line of the partition), right-click a disk whose size you want to contribute, such as disk F, click cut partition, and fill in the size you want to give to disk C in the new partition size. For example, if you want to add 10G drive C, please fill in 10G here. After cutting is completed, right-click the newly divided area to delete the partition, then right-click drive C, click merge partition, check drive C and unallocated disk, and confirm. Finally, complete the submission in the upper left corner of the program. The following is a detailed diagram, please remember, this is a very simple question.

Please follow the mouse operation in the screenshot and it will be completed in a few minutes.
