Where media get stored in seatable self-hosted server?

I have hosted Seatable on my server and it working pretty fine but, I am having some doubts about the media storage in the server. I know that the attachment and the files stored in Seafile storage DB but however I am not able to see them there. Even though I have deleted it from Seatable web interface it is still taking the storage in my cloud storage. Can someone help me regarding this issue.
