A Microsoft file hosting and synchronization service.
Hi @M_P,
Thank you for posting your question in the Microsoft Q&A forum.
Based on the information you have provided, it looks like you have problem with downloading large files from OneDrive.
According to this article: Download files and folders from OneDrive or SharePoint, downloads are subject to the following limits: individual file size limit: 15GB; total zip file size limit: 20GB; total number of files limit: 10,000.
However, to download large files in OneDrive to your local disk, I would suggest use OneDrive sync client, if you just want to download part of the files in your OneDrive to local disk, there is a feature called OneDrive Files On-Demand. But if you want to download all the files and folders to your desktop, you can turn off the feature in OneDrive settings.

I hope this information helps.
