Why Merge Partitions Windows 7

Windows 7 users, actually more and more Windows 10 users are involved nowadays, once feel it necessary to extend a disk volume in order to hold more data, games, or programs. Some choose to directly resize a partition, while some choose to combine two partitions into a large one. Do you know in what circumstances people want to merge partitions? The following are some examples.

  • The system C drive is running out of space. As a result, the computer becomes extremely slow, or the system starts freezing a lot.
  • Too many hard drive partitions are scattered on a disk, making it difficult to locate files or make full use of every bit of hard drive space.
  • There is unallocated space on the disk. It's helpful to add unallocated space to some partitions.

The displayed examples all refer to one problem: improper disk space distribution. Therefore, to utilize disk space carefully and efficiently, it's a good idea to merge partitions in Windows 7, 8 or 10. By combining two hard drive partitions into one can help create a new volume with sufficient free space, to minimize the hard drive numbers, as well as to solve the problem of low disk space warnings.

In general, there are two typical ways to merge partitions in Windows 7. One is the built-in Windows Disk Management and the other is third-party partition manager software
