Windows 10: OneDrive: Dozens of files are stuck syncing and cannot be downloaded, with error code...

I have a folder synced with OneDrive, using Files On-Demand. Most files can be downloaded with no issue, but dozens of files have the syncing arrows next to them, and attempting to load them fails. It shows a popup with the text "Error 0x8007017F: the cloud sync provider failed to validate the downloaded data". I can double click other files and download them as normal.I also tried to download some of these problematic files on OneDrive.com. Pressing the Download button did nothing. I could download other files without issue, but I could not download the same files that I could not sync.T

OneDrive Placeholders are coming back, now called On-Demand Sync




"At Ignite 2016, Microsoft has just announced that it is bringing Placeholders back to OneDrive on Windows 10. Now, they are not called Placeholders anymore — Microsoft is renaming the feature to “On-Demand Sync” which makes a lot more sense than “Placeholders”.

The company demoed this feature at Microsoft Ignite today, and it works just like it used to previously. As you can see in the screenshot above, the files stored in OneDrive weighed in around 9GB, but the actual size on disk was only around 3MB which is really neat. Of course, this feature isn’t anything new as it was available back in the Windows 8 days. However, Microsoft removed the feature with Windows 10, and after lots of waiting, they are finally coming back.

In case you are not familiar with OneDrive Placeholders, it’s a pretty neat feature which lets you see all of your OneDrive files on your computer — but they are not actually downloaded on your PC. When you open them, OneDrive will download the files on-demand, saving your local space which is really useful, especially if you have a PC that doesn’t have a lot of storage.

While Microsoft didn’t announce when exactly On-Demand Sync will be available to OneDrive users, we suspect it will be available with Windows 10 Redstone 2 — which is expected to arrive early next year. "

Windows 10 - OneDrive

Right click on the app and one of the properties has an option to not automatically start it. Uncheck, restart the computer, and it should stop. If you want to go another step further, find the OneDrive app in the start menu, right click on it and uninstall.

If that is still insufficient, there is a batch uninstaller for OneDrive available online. I can copy the code here if you need it.
