A family of Microsoft word processing software products for creating web, email, and print documents.
Thank you for the reply. I read this post, and the other one you linked to, and the one Neha linked to, and the article that that post linked to as well.
Your linked post about the relative paths was the only one that told me anything potentially useful, and even that fell short in that I am working from a cloud folder that is synced to my computer, and the files in that folder have C:/ paths listed in their properties rather than their actual cloud-based paths. This is probably a shortcoming of Windows 10, another Microsoft product. Even if what I'm trying to do is possible with cloud-based files, it requires technical ability and diligence that people who are using products like Word shouldn't be expected to need.
According to the post linked by Neha, and the post embedded within that one, the whole practice of trying to link documents together in MS Word is best avoided altogether. This has been the case for at least 10 years it seems, and has only gotten worse with the advent of cloud file storage. I hope Microsoft will fix their product to work as advertised, or remove the functionality entirely if they cannot.
