A Microsoft file hosting and synchronization service.
Hi, Eije Iveroth
According to your description, you may have mistakenly turned on the backup or file-on-demand function of OneDrive, which will cause your files to be uploaded to OneDrive, and then the files left locally will be deleted.
Then you want to download your document files back to the local computer, right?
According to the information you mentioned at the beginning, the document got stuck and OneDrive crashed after downloading. So did the situation improve after trying my solution (resetting OneDrive)?
Of course, if the situation of your OneDrive client still does not improve, you can also log in to your OneDrive web client to download the files you want back to the local computer.
Best wishes
