Why and how to move free disk space on Windows server 2012?

Nowadays, popular server operating system is Windows Server 2012. However, “Low Disk Space” is a common disk space usage problem in Windows Server 2012 all editions, many people don’t know how to remove low disk space warning or fix this issue. In fact, it is easy, just move free disk space on Windows Server 2012 to fill the low space partition.

Next, let me describe the problem in detail. We used the computer for a while, we would find that the partition is getting smaller and smaller, especially C: drive. So Windows created the “Low Disk Space” warning to alert computer users when their hard drive is running low on available disk space. It also gives you a shortcut to free space by deleting old or unnecessary files. Following are some free tips you may use to free your c drive:

  1. Delete Temp Files on system.
  2. Uninstall unnecessary applications.
  3. Shut down Windows update if possible.

All above tips are temporary ways. You can change a bigger hard disk, but your server will be interrupted undoubtedly. Better solution is moving free disk space on Windows Server 2012 to expand the low space partition(partition C) with partition tool. Easy in theory, but hard to practice. Because Windows Server 2012 disk management has some limitations when using it. For example, if you want to expand C: partition with it, there must be an unallocated partition behind drive C.
