In some cases, you can mount the folder from other drives and extend to C drive without deleting or formatting other partitions. If you need to delete the other partitions to extend the C drive, then you must do that if extending the C drive is so important. So basic requirement, make some free space next to C drive on the same hard drive. In that case, you need to move the partitions and extend the C drive – which is too complicated and we are not going to discuss that here.
Even it will be tough with the other third-party tools if you do not have free space next to C drive. If you have C, D, then some free space, this method is not applicable. This free space should be next to the C drive. Important point again: To extend the C drive, your hard drive should have free space.
