Disk Cleanup is a tool that allows you to remove temporary files and other unnecessary data that cannot be deleted through Windows File Explorer, providing a solution to a full C drive.

1. Right click the C drive in File Explorer, select "Properties", and then click "Disk Cleanup" in the window that appears.

2. Windows will scan your C drive and calculate how much space you can free from this drive. It will then present you with a list of files and folders that are taking up space and give you the option to delete them.

3. To delete files from a drive, select the files you want to delete, then click "OK" to confirm the deletion.

From there, right-click on the program you want to remove and select "Uninstall".

│Solution 6. Merge unallocated space into C drive

Besides freeing up disk space, you can also try to extend C drive to make it bigger. This can usually be done using the Disk Management tool by right-clicking on the C drive and choosing "Extend Volume", but only if there is an adjacent unallocated space behind the C drive. Otherwise, the "Extend Volume" option will be greyed out.

Qiling Disk Master Professional can easily merge unallocated space into the system partition, even if it's behind the C partition, in just three steps, making up for the shortcomings of Disk Management.

1. To start, install and open Qiling Disk Master Professional. Then, right-click the C drive and choose "Disk management" from the menu, followed by selecting "Move/resize Partition" to proceed with the process.

2. In this window, select the C drive and another unallocated space.

3. You need to click "Proceed" to commit the pending operation, which will require a reboot after it's completed.

▸If there is no unallocated space on the same disk, you can create a new partition on a different disk or expand the existing partition by allocating more space from the same disk.create unallocated space Qiling Disk Master allows you to resize, shrink, or delete partitions on a disk using its "Shrink Partition" and "Delete Partition" features. This enables users to free up space on their disk by reducing the size of a partition and then using the reclaimed space for other purposes, or completely removing a partition to eliminate any associated data and make room for new storage needs.
▸To merge partitions, you can combine two adjacent partitions into a larger one, but only merge a data partition into the system boot drive, not the other way around.

│Solution 7. Allocate free space from other partitions to C drive
