When we talk about & # 39; disks & # 39; with the label C:, D:, and so on, we are actually talking about partitions, sections of the physical disk. Each hard drive used has at least one partition. You can shrink that partition and create new ones from the extra space. You will find this useful if you want to install more than one operating system, or if you really want to separate programs & data.
But first you have to take some precautions.
Step 1: Make a complete image backup of the entire disc if you do not have one yet. Disasters happen. (See our choices for the best Windows backup software to get you started.)
Step 2: Make sure you have enough free space on the existing partition to create the new one. The following articles may be useful to free up space:
You may also want to empty the recycle bin.
If you still do not have enough space, you can move files to an external drive. After partitioning is complete, you can move them back to a new partition.
Step 3: Open the Windows partitioning utility. Windows comes with a reasonably useful partitioning tool. It is likely to meet your needs, and if you don't, you will know soon enough. To open it, type partition in the search bar and then click Create and format hard disk partitions . (In Windows 8, type partitions ̵
Step 4: Decrease the existing partition. Right click on the partition and select Decrease volume.
Then wait. It may take a while. Finally, a dialog box asks how much you want to shrink the partition. The default number is the maximum available.
And therein lies the problem of Disk Management. If the current partition has 228GB free, you should be able to reduce it by slightly less than 228GB. But with Disk Management you may not be able to shrink it that far. If the program does not allow you to shrink the partition as much as you want, go to the last paragraph.
