C Drive is Full How to Fix

When your C drive is full and you want to extend it, you can use the command based Windows utility i.e diskpart. Diskpart has replaced disk command utility with more advanced features.

Using the diskpart commands, you can extend, create,delete,shrink,clean,delete and perform other disk resizing tasks. If you want to extend your C drive, and you see your unallocated space next to C drive then it is is simple to extend your C drive using diskpart. You need to go to RUN->Type diskpart.exe and press OK.

Once you are in Diskpart, you can type in commands to resize partitions. For example you want to extend your C drive. You run the command - list volume and see the unallocated partition next to your C drive that you want to extend. You run the next command - extend size command and the drive is extended.

If the unallocated space is not next to C drive, then you can delete the next partition and extend your C drive. Both the partitions C and contagious partition must be of the same file system. This way you can extend C drive. Deleting a partition means you are deleting the data stored on the drive. If the file system of the next drive is not NTFS then then you need to format the next drive in NTFS. Diskpart supports only NTFS partitions.

The basic diskpart commands:

1. Run->diskpart.exe: This takes you to diskpart command mode.

2. List Disk: To view the disks connected with your system.

3. List partition: To view the partitions

4. Select partition: To select the partition. If you want to do any disk activity on any partition, you must select the partition first.

5. Shrink-To shrink the drive. This creates unallocated space which can be added to other drive.

6. Extend- To extend your drive.

7. Format- To format the partition

8. Merge-For Merging partitions.

9. Create-To create a partition.

10. Delete-Use this command to delete a partition.

The diskpart is a command based utility. Most of us are not comfortable and sure in when typing commands to do any resizing activity. If you type a command and by mistake press enter, you will not be allowed to cancel the activity. This is a risk when you are not sure about diskpart.
