Creating a project shows "Error: ENOSPC: no space left on device error."

When you try to create a project, you might see an error something like below. It means your Hard Disk Drive is full so please clean up your Hard Disk by removing unnecessary files and then try to create a project again.

Error: ENOSPC: no space left on device, mkdir '/Users/hidekoji/.exploratory/projects/Demo__uMG3rNQ8'
