Windows – Split a folder of files into multiple zip files based on size or # of files

My problem is that the file uploader I'm working with will only allow a zip file with a size of 10mb or less. Unfortunately, I have thousands of files that need to be processed and I do this by uploading multiple 10mb zip files, manually.

How would one go about doing so automatically?

Things to consider:
^{– (software wise) If there is no way of knowing what the compressed size is going to be before
– hand maybe there would be a way of selecting how many files are allowed to be in each zip file?
– Maybe similar to these questions but on Windows? Compress a folder into multiple zip files, https://apple.stackexchange.com/questions/12371/how-can-i-compress-a-folder-into-multiple-zip-filess}
