VMware How to Extend C Drive Partition in Windows Server 2003, 2008

Have you ever encountered low disk space warning on C drive when using VMware Windows guest? If so, it means that you will be confronted with high-risk data loss and low work efficiency with the virtual machine. Besides, defragment and more installations are not available. In general, there are three symptoms when you need to extend C drive in VMware

Symptoms 1: There is enough free space in other data partitions other than C drive. For example, system partition - C drive is almost full but data partition - D drive is empty.

Symptoms 2: The virtual disk only holds a single C drive for system. In such case, you need to increase the size of virtual disk in advance. Then, merge unallocated space in to C drive.

Symptoms 3: You have increased the size of a virtual disk with vmware-vdiskmanager or VMware GUI (The disk was successfully expanded. You must repartition the disk and expand the file systems from within the guest operating system), but C drive capacity is the same as ever.

No matter which symptom you face, you can solve your VMware C drive low disk space warning problem to increase the efficiency of Windows-based guest system administration with complete and reliable Partition Magic Server Software - Partition Assistant Server Edition.
