HA on QNAP VM Getting BIG!

Hi!

I’ve been running my HA on a VM on my Qnap NAS and it has been running pretty well beside taking a lot of space by creating some “home-assistant.xxxxxxx” files as you check in tha attached printscreen.

So… My questions are why is this happening and what are these files? Is there something wrong with my config? Can I delete these files or just the older ones? How should I deal with it? What Am I missing?

Looking forward for your feedback! Thanks

Cheers

I believe those file are the VM snapshots, I thought they were placed in another location.
