Finding the last modified date for Orphaned vmdk file

Hi All,

I am planning to delete the Orphaned/Zombie file and after looking through the vSphere platform, it has come to light that there are THOUSANDS (well over 10,000) of orphaned VMDK files, looks like this is not easy to delete. Is it possible to check the last modified date for Orphaned file ?

Thanks
