Concatenate binary files

How To
1

I’ve got several files in google drive which represent a ZIP file which has been split into parts. The way you reconstruct the ZIP is simply to join them.

I am downloading them with the google drive download module but I’m having a really hard time figuring out how to do the simple concatenation to be able to upload the reconstructed file. Although the data from the download is binary, all my attempts to join them seem to fail due to a conversion to text I think.

Any help would be appreciated.

Could you provide links to those example files so we can have a go?

Thanks for asking but not really. You could, however create two google docs, one containing 123 and the other containing 456 and download them, pull out the data from each and try to upload a file containing the combination of the data which would be 123456

That wouldn’t work the same way as split zip files though.

Well, no, but in the end this is about adding 2 binary blobs together. I’m not sure it matters where they are from.

I aggregated the zip files into an array. So the array has 3 elements, each of which is binary. How could you iterate through them to get a concatenation of the binary?

Thanks!
