OneDrive Settings: The Four That Actually Matter

Your Documents folder moved into OneDrive and your Downloads folder did not, and nobody asked you about either. Both of those are settings.

There are dozens in there and four of them decide everything you notice day to day. The rest you can leave alone forever.

I read which of my own folders had been moved, and the split was not what I expected.

Where the settings actually are

Two clicks. Almost nobody finds them by accident.

Documented by Microsoft on its folder backup page: "Open OneDrive settings (select the OneDrive cloud icon in your notification area, and then select the OneDrive Help & Settings icon then Settings.)"

⭐ The cloud icon by the clock is the way in. Not Windows Settings, which is where most people look first and find nothing.

⚡ Everything below lives on two tabs, Sync and backup and Account.

Setting one: which folders it has taken

The one that explains why your files moved.

Microsoft names the folders it can back up: "Desktop, Documents, Music, Pictures, and Videos" on Windows.

Ours, and read off the account on this PC. Documents and Pictures point into OneDrive. Downloads does not, and it is not on Microsoft's list at all.

⭐ That split is the whole confusion. Two of your folders are in the cloud, one is not, and File Explorer shows them side by side as though nothing happened.

⚡ Change it under Sync and backup, then Manage backup. Each folder has its own switch.

⚠️ Stopping is a choice, not a click. Microsoft says you pick between keeping files "only in OneDrive, removing them from your computer" or "only on my PC, removing them from OneDrive."

Setting two: Files On-Demand and the icons

The one behind the little symbols. And the missing gigabytes.

In Microsoft's words on its Files On-Demand page, it "helps you access all the files in your cloud storage in OneDrive without having to download them and use storage space on your computer."

⭐ Three states, three icons. A blue cloud means "the file is only available online". A green tick means it downloaded when you opened it. A green circle means you marked it "Always keep on this device".

⛔ And the catch, from Microsoft: "You can't open online-only files when your device isn't connected to the Internet."

⚠️ Ours: mark the folder you need on a plane before you get on the plane. That is the only version of this that ever goes wrong.

Setting three: how much space it is really using

Where the full-drive confusion comes from.

⭐ Online-only files show a size in File Explorer and occupy almost nothing. So the folder total and the disk usage disagree. On purpose.

⚡ Right-click a folder and choose Free up space to push it all back to online-only. Right-click and choose Always keep on this device to do the reverse.

⚠️ If the drive is genuinely full, OneDrive is rarely the largest thing on it and there is a proper order for finding what is.

Setting four: the account tab, and unlinking

The one to know exists. Before you ever need it.

⭐ Unlink this PC stops the whole thing without deleting anything from either side. It is the calm option.

⚠️ It is not the same as turning OneDrive off properly, and doing that has an order worth following so your folders end up where you meant.

⚡ Choose folders on the same tab lets you sync some of the cloud and not the rest, which is useful on a small laptop drive.

What OneDrive is not

Being plain, because this costs people files.

⛔ It is not a backup. Delete a file on the PC and it deletes in the cloud. That is what syncing means.

⚠️ The recycle bin buys you time, not safety. It holds deleted items for a limited period and then they go.

⭐ Ours: I keep a separate backup for exactly this reason. A real backup keeps a copy somewhere that does not change when you change something. Sync and backup are different jobs.

The version, and why it matters

Short, because the interface has moved twice.

Ours, and read here. The client reported version 26.145.0728.0011, which is the current layout with Sync and backup as a tab.

⚡ Microsoft states a floor for Files On-Demand: it "requires version Windows 10 1709 or later, or Windows Server 2019".

⚠️ Older screenshots show a different dialog. If the tabs on your machine do not match, check the version before following anything.

When it will not stop asking

Practical. It is the complaint underneath a lot of searches.

⭐ The nag to back up folders returns after major updates. Declining it is a choice each time. It is not remembering yours.

⚡ Ours, and marked as ours: decide once whether you want folder backup on, then set it deliberately rather than dismissing prompts. Half-answered prompts are how people end up with two of three folders moved.

⛔ And if you want it gone rather than quiet, that is a different job with its own steps.

Status: opened and read 25 August 2026 on Windows 11. Microsoft supplies the settings route, the list of folders it can back up, the choice offered when you stop backing one up, the description of Files On-Demand, the three file states, the statement that online-only files cannot be opened offline, and the Windows 10 1709 floor. The folder redirection and the client version came off the account on this PC.

Why did my Documents folder move into OneDrive?

Because folder backup was switched on, probably during setup or after an update prompt. Microsoft lists Desktop, Documents, Music, Pictures and Videos as the folders it can take. Downloads is not on that list, which is why it stays put.

What do the OneDrive icons mean?

A blue cloud means the file is online only and takes almost no space. A green tick means it downloaded when you opened it. A green circle with a tick means you marked it Always keep on this device.

How do I stop OneDrive syncing a folder?

Open OneDrive settings from the cloud icon by the clock, go to Sync and backup, then Manage backup, and switch the folder off. Microsoft then asks whether to keep the files only in OneDrive or only on your PC.

Is OneDrive a backup?

No. It syncs, which means deleting a file on the PC deletes it in the cloud too. The recycle bin holds deleted items for a limited period and then they go. A backup keeps a copy that does not change when you change something.

The Short Version

• OneDrive settings open from the cloud icon by the clock, not from Windows Settings.
• Microsoft can back up Desktop, Documents, Music, Pictures and Videos. Downloads is not on the list.
• On this PC, Documents and Pictures point into OneDrive and Downloads does not.
• Files On-Demand gives three states: online only, downloaded, and always kept.
• Microsoft states you cannot open online-only files with no internet.
• Online-only files show a size but occupy almost nothing, so totals disagree on purpose.
• Unlink this PC stops syncing without deleting anything on either side.
• Syncing is not backing up. Deleting locally deletes in the cloud.

Where to Next

Open the settings from the cloud icon and look at Manage backup. Two minutes tells you which of your folders are actually in the cloud.

If any of them surprise you, switch them deliberately rather than leaving it half done. Two of three folders moved is the state that confuses everybody.

Then mark anything you need offline as Always keep on this device, before you need it rather than after.

And if your Downloads folder has somehow ended up inside OneDrive on your machine, tell me how in the comments. Microsoft does not list it, so that would be worth knowing about.
