How to Reallocate Disk Space from D to C drive in Windows 10/8/7?
Geeks - If you're running low on disk space on your C drive (the drive where Windows is installed), you can reallocate some of the space from another drive, such as your D drive, to the C drive. Here's how to do it in Windows 10, 8, and 7:
Open the Start menu and search for "Disk Management." Click on the "Create and format hard disk partitions" option that appears.
In the Disk Management window, right-click on the D drive and select "Shrink Volume."
In the Shrink dialog box, enter the amount of space you want to reallocate to the C drive in the "Enter the amount of space to shrink in MB" field. You can use the slider to adjust the size of the shrink.
Click "Shrink" to confirm the shrink operation. This will create unallocated space on your D drive.
Right-click on the C drive and select "Extend Volume."
In the Extend Volume Wizard, click "Next" to proceed with the default options.
In the Select Disks window, ensure that the checkbox next to the D drive is checked, and then click "Next."
Click "Finish" to complete the operation. The unallocated space on the D drive will now be added to the C drive, increasing its available space.
Note: You may need to move some files around or delete unnecessary files to fully utilize the newly added space on the C drive.
