It might bring much inconvenience when disk partition is lacking space on Windows Server 2003. For example, your computer may run more and more slowly if system partition runs on low disk space, or you are unable to store more data to the partition that is lacking of free space. The most common method that most users would like to select is to delete or move some files to release some space.

However, if you want to solve the low disk space problem thoroughly, the best way is to rely on third-party partition software to reallocate disk space on Windows Server 2003 without formatting disk.

How to create unallocated space on SERVER 2003?

Way#1 - Shrink a volume without losing data

Partition Resizer Server and Disk Management can both shrink volume without losing data. However if the produced unallocated space is not close to the target drive, Disk Management cannot move the unallocated space but Partition Resizer can do the job.

Step1: Right click the large volume, go to Resize/Move Partition optionresize partition

Step2: Shrink the volume by narrowing its border.

And then the unallocated space will be created at the left side of the shrinked partition.

Way#2 Delete partition

Both Disk Management and Partition Resizer can delete volume with the result of losing all data.

It's upon your own choice.

Once the partition is deleted, there will be unallocated space created on the disk that you can redistribute the unallocated space to any partition with Partition Resizer. (Disk Management cannot move unallocated space.)

Note: Disk Management can only extend an NTFS volume when you delete its right side partition. (It cannot extend a fat32 partition even when there is unallocated space at its right side)

Data Volume Runs Low Disk Space Server 2003

"I have stored lots of data on D drive on Windows Server 2003, and now it is nearly full. I don’t have an external hard drive to backup the data, but I can no longer save more data to this drive if I don’t move or delete any file. However, all files stored on this drive are quite important to me. There is no other data volume on my computer, but there is a C drive which contains operating system. C drive still has lots of free space, but I don’t want to store my data to C drive. Is there any way to move some free space from C drive to D drive?"
