If a download abruptly fails, what happens to the chunks that made it into vaults? I imagine that they are retained by the network. Deduplication will prevent chunks that were already uploaded from being reinserted. The remaining chunks will complete the file once reuploaded regardless to who does it. Is this correct?
Another question. If the file is already on the network (uploaded by another user), will I have to pay when I try uploading it again? Will the network tell me it already exists?
