I am using My Cloud Home DUO 16 TB in Raid 1 config so I started with 8tb space. I have 4 users using it including me. after 5 years or so when I check the space left and usage I got a shock. Why do I have have only 0.6 TB free space left when I am only using aproximatly 3 TB. How can clean un used files by the system and reclaim the space I should have
