Make your life easy!
When we buy a brand new PC, almost everything has been settled by the reseller. Just get it and use it. Years' use of the PC makes it never like the moment you got it. Windows keeps eating the hard disk space: the longer the time is, the slower PC becomes. Low disk space alert pops up every time you do the Windows update. System break or even system crash happens to you and destroys everything that might be your painstaking effort.
Not so hard to find the source of all these annoyances: inappropriate disk space distribution. This means you fail to arrange disk partition size properly; some are too large and some are too small. Enough space should be spared to C drive for Windows files and updates. All those problems I listed out above are often triggered by System C drive of no extra space for use. A consolatory fact is that disk space can be redistributed again with partition tool. Here I will mainly introduce a way to extend drive by merging partitions and make full use of disk space.
You would be the lucky one if your operating system is Windows vista or the after. Disk Management enables you to redistribute disk space to a certain degree and using this tool to finish this mission just takes a few mouse-clicks.
Suppose your system C drive is out of disk space, D drive is a data partition after C drive with large amount of free space and the Operating system is Windows 7. Disk Management realizes merging partition in an indirect way.
Copy all data in partition D into another safe place or back up all data into image.
Then, right click "Computer" > choose Manage > Disk Management> right click D drive and choose "Delete Volume".
After getting unallocated space, right click C drive > choose " Extend Volume" > claim the unallocated space into C drive.
Then merging C drive and E drive has been successful. On one hand, this way is very simple and free, no professional tactics are needed. On the other hand, it has many limitations. The cost of using Windows toolkit is to delete another partition.
Indeed, Windows provides many functions for our choice; however, many of them are limited to certain degree. Always having a backup is the right thing you should do. So when you find your case is not applicable with the help of Windows toolkit, you should switch to third party partition software. You may hear your friend say or mention one partition utility - EaseUS Partition Master Free Edition: a freebie and enjoying great popularity among partition software.
