Increasing size of the OS Partition/Drive of a VMWare Virtual Machine Virtual Disk

If you want to extend the OS drive of your VMWare Virtual Machine, you can follow the steps given below:

1. Shutdown your Virtual Machine.
2. Remove all Snapshots created for the Virtual Machine.
3. Right Click your Virtual Machine and select Settings: navigate to 'Hard Disk' : select Utilities and expand the partition.
4. Now Power On your Virtual Machine and      install a Partition manager (such as Partition Magic, Paragon Partition Manger): allocate the un-allocated space as “primary” partition
5. Now simply use 'merge partition' option to merge the partitions ( OS partition should be taken as ‘basic’ )
