Increase C drive space in Windows 10

This article introduces how to increase C drive free space in Windows 10 without formatting or reinstalling OS. Increase system C drive space from D, E or any other volumes.

No matter you use OEM laptop/desktop or build the computer DIY, disk space of system C: drive and other data volumes are allocated. Many types of files write in to system C drive, so it’ll become full some day. What will you do in this situation? Actually, you can increase C drive space in Windows 10 without reinstalling Operating System and programs.

A increase partition size in Windows 10, there are two choices: Windows 10 native Disk Management and third party partition software such as NIUBI Partition Editor. In this article, I’ll introduce how to increase C drive disk space in Windows 10 (32 bit and 64 bit) with both tools.

Increase drive space with Disk Management

Windows 10 Disk Management has build-in Estendere il volume functionality which can be used to increase partition size without losing data, but not every drive can be extended. In fact, Extend Volume only works when disk partition configuration meets the requirements below:

  1. Extend Volume is only valid for NTFS and RAW partition, FAT32 and other types of partitions are not supported.
  2. There must be adjacent Unallocated space on the right side of the drive that you want to expand.
  3. Free space in Extended partition cannot be added to Primary partition, even if it is right adjacent.

Because of the restrictions of both Shrink and Extend Volume functionalities, you can’t extend C drive by shrinking D in Disk Management. The only option is by deleting partition D to get adjacent Unallocated space.

Attenzione Do NOT delete drive D if you installed programs into it, remember to back up or transfer files before deleting a partition volume.

Steps to increase C drive space in Windows 10 Disk Management:

  1. Clic destro del mouse Finestre on bottom left corner of the screen and then select Gestione del disco.
  2. Fare clic con il pulsante destro del mouse sull'unità C e selezionare Estendere il volume.
