6. If garbage cleaning can't solve the problem, use DiskGenius tool to expand disk space without loss.
For example, disk C plans to expand 15GB.
Start the computer with the U disk PE, run the tool, right-click the D disk, select "Adjust partition size", enter 15GB as "Space before partition" and press enter, and select "Merge to the C disk" on the right to start. To be on the safe side, it can be done in two steps. First, vacate the front of disk D, and then merge the vacated area into disk C. Note: Try not to cross-adjust, such as transferring the space of disk E to disk C..
If you don't have a USB flash drive PE, use "God's will BIOS+UEFI dual boot+three partitions" and bring your own one-button production tool, which is simple to operate. After entering PE, directly use the DiskGenius tool in all program menus.
