Windows Updates, services, applications and several other types of files write automatically into system C drive continuously daily. It is imperative that your C drive becomes full someday, especially in a situation when your C drive was built with less than 50GB.

It is a common occurrence daily to see the C drive running out of windows, thereby depriving the system of space and capacity to run effectively.

The quickest avenue to provide a solution to this problem is by trying resize partition. Reduce another disk capacity to enable free space and then add the space into your C drive.

Some tips you should know before extending your C drive

There are different things you should know about before going on to extend your C drive if you don’t want system malfunctioning. They are as follows:

Ensure if there is any free space in any other capacity on the same disk.

No partitioning software can change the size of partitions beyond two hard disks. This means the capacity that takes free space to enlarge C should be on the same hard disk.

It is advisable to close other applications you are using before extending your C drive.

You should pay adequate attention to data safety.

Unlike the read-only operation, to change the size and enlarge the capacity, the partitioning software will change all parameters linked to this disk, partition and all files in the capacity. A little error may give rise to data loss, so it is essential to choose a reliable tool like the IM magic FREE edition.
