If I upload a specific size file, can that be tracked to my device?

By uploading specific file sizes, could this information be used to know what the file is, even if encrypted? Which could lead to ISPs knowing if you uploaded a copyright file. Assuming you are not using a VPN.

By using hash tables could these files then be known? Or because all the information is spread out would this be ok?

Is information stored linking all the chunks together that would constitute a file, and could the hash of known files be matched up with this?

No files are chunked, and encrypted. Chunks are spread out over the network. AFAIK, there is no means for an attacker to determine files size for private data.

No, as chunks are highly encrypted and in a very unpredictable way and then nodes also encrypt chunks, so what is stored (if it could even be found) wouldn’t match any hash tables.

I believe that for private data the data-map is only accessible to you.
