How to increase C drive disk space without losing data?
Windows create the low disk space warning to alert computer users when their hard drive is running low on available disk space. The first warning appears when a drive has less than 200 MB of available disk space, the second warning appears when the drive has less than 80 MB of available disk space and the most urgent warning appears when the drive has less than 50 MB of available disk space. As your disk space decreases, the frequency that the low disk space warnings pop-up on your screen increases.
On Windows XP/Server 2003
On Windows Vista, 7, Server 2008
In some Windows versions such as Server 2012, you’ll see the C drive becomes red after opening My Computer.
No matter you are running Windows XP/Vista/7/8/10 or Windows Server 2003/2008/2012, you can increase C drive disk space directly without losing data or reinstalling Windows.

Solve the problem ASAP
When there is not enough free space left in system C drive, you should try to solve this problem as fast as possible, because:
- System runs much slower.
- You cannot install Windows updates and applications.
- System crash if extremely low free space remains.
Follow the steps above, you can easily increase C drive space by taking unused space from other data drives. BTW, you’d better change the way running your computer:
- Keep data separate from the Operating System, one partition for Operating System, one partition for applications and the others for data.
- Change default download and cache path of the applications out of C drive.
- Delete caches and temporary files with Windows built-in Cleanup utility regularly.
