How find a file by hash?

Hello everyone,

I have a question and after searching for a while I haven’t got an answer so here goes.

In some Dockerfiles I have found the following tag:

ADD file:d9efaba9e396cd5732f1689338ef5f1fbb66667806efe9c6938ca7169b305496 in /

Is it possible to view/download the file before starting the container? How can I download it with just the hash?

Thanks for the help and sorry if this is a stupid question,

No, that seems to be the base filesystem anyway, so not a single file.
