More Information

Those of you who use Microsoft Windows may be familiar with an error message about low disk space on Drive C: here is what happens; You don't get any more updates from Windows, no Anti-virus or Anti-malware updates either. And you don't get to store any new data because there isn't any free space in the first place.

Lucky for Windows users, Windows has provided with a built-in tool called Disk Management, which controls all the basic as well as advanced actions regarding disks or local drives. It can execute a series of commands like to shrink a volume, create, extend, merge, delete or even format the volumes.

So, in particular, we deal with an issue regarding Local Disk C: on the disk management tool. When our space in C drive is filled up, we tend to extend the volume, but can't seem to do so. Because when we right click on drive in disk management in order to extend its volume, the extend volume option is greyed out. Mean's you can't access or execute the respective action. In simple words you can't extend greyed volume.
