There is a Google Ngram file that I want to download which is like a Terabyte in size (after extraction). It's too big for me to download, but I don't need the whole file all at once. I could just download a portion of it, use it, delete it, and then download the next portion.

Is there a relatively simple way to do this? I normally extract these kinds of files with 7-Zip. But I doubt that with 7-Zip you can partially extract files like this.


You have to download whole file to extract part of its contents. It's same with split archive (.rar, .r00, .r01 ...) If you download 99% of file, stop download, and try to extract it, only thing you can get is corrupted file error.

It's just like tear some pages from really large book. If you want to get some pages from volume 3 of it, you have to get whole book first.

But, if they provide part of file - like vol1.zip, vol2.zip. In this case, it's like tear pages from set of books. If you want to get some page from volume 3, all you need is just take one book from set.
