Hyper V - Cluster Storage Volume is Almost Full

Hi,

Could you please advise and recommend the best practices as per Microsoft,  if you can move/delete Non-Critical files from the below location to another location to free-up some space.

Please if you can advise me the steps to delete as per Microsoft recommendations. 

C:\ClusterStorage\Volume1\VM-Name\Virtual Hard Disks

Please find the below screenshot for your reference.

Kind Regards,
