The second solution to increase the C drive is to add disk space to C drive in Windows server 2019 with Disk Management by the following options:

• 1, Shrinking volume on another big drive on the same disk or another disk if raid is built to create unallocated space.
• 2, Delete volume in Disk Management to create unallocated space
• 3, Add a new disk to Windows Server 2019 and redistribute the free space to c drive by using RAID array

Step2. Right click the partition which is contiguous to c drive and Delete Volume. (Please do backup data to another drive at first since deleting volume would erase every file on the partition)

Note: If you do not want to delete volume, you may use 3rd party software Partition Resizer to redistribute disk space from one partition to another without losing data.

Step3. Right click c drive and go to Extend Volume to expand server 2019 c drive in Disk Management after you deleted the c drive contiguous volume.

Note: Disk Management tool works only when your files system is NTFS, and you can not extend the partition if there is no unallocated space adjacent to the partition or when your c drive is fat32 partition.
