How to Merge Partitions to A Bigger One

If you have a partitioned hard disk and you are running out of space on one of the partitions, you can choose to merge partitions operation. For example, your computer has three partitions—E, C and F. Windows 7 is installed on C: and C: is 25.43GB, while F: is 74.47GB.

Now you want to merge F: into C without formatting C and without reinstalling Window 7. How can you merge partitions C and G without losing data? This is an important topic for all the users because if you merge Drive C and Drive F improperly, you may lose your data which would cost you some hundred dollars to recover your data.

  • Partition Assistant could support at maximum two partitions merging every time.
  • To merge partitions, the two partitions must be adjacent.
  • You could merge data partition into system partition, but could not merge system partition in to data partition.
  • In Windows 7 the "system reserved" partition could not be merged.
