OneDrive – synchronization of selected folders and Files On-Demand

Why it’s worth combining selective sync with Files On-Demand

OneDrive can organize your daily work perfectly: you store files in the cloud, share them with others, and access them from different devices. The problem arises when your local drive runs out of space or when you don’t need all the data "at hand". This is where two often-confused features come in, which together give the best effect:

• Selective folder sync – you decide which folders actually appear on the device.
• Files On-Demand – within synced folders, you set which files are online-only and which are available offline.

In practice: selective sync is an "input filter," and Files On-Demand is an "availability switch" for specific files. This way, you not only save space but also reduce the number of items the sync client constantly monitors.

Selective folder sync – how it works and when to use it

Selective sync does not delete data from the cloud. It only changes what you see in the local OneDrive folder. If you deselect a folder, it disappears from the computer (its copy remains in the cloud), and you can restore sync at any time.

Most common usage scenarios

• You have a huge photo archive but only need current projects on your laptop.
• You share OneDrive with a team and want to keep locally only the folders you actually work with.
• You want to limit the number of files indexed locally (which can speed up slower computers).

Step by step: selecting folders to sync

The following steps are very similar on PC and macOS – mainly the location of the OneDrive icon differs.

1) Open the OneDrive client settings

Click the OneDrive cloud icon in the notification area (or the menu bar on Mac), then go to settings.

2) Go to the account section

In settings, find the tab/section related to accounts and synced locations.

3) Select folders

Use the "Choose folders" option, then uncheck the directories you don’t want on the device. Confirm changes – the client will organize the local structure automatically.

Tip

If you deselect a folder with many files, give OneDrive a moment to complete the operation. During changes, avoid moving large amounts of data in the same area to prevent version conflicts.

Files On-Demand – files on demand without taking up space

Files On-Demand lets you "see" all your files, even if they are not downloaded. They appear in File Explorer with status icons, and downloading happens only when you open a file or when an app really needs it. This solution is especially useful when working with large data packages (graphics, video, CAD projects) and you don’t want everything to immediately fill up the drive.

Three file states worth distinguishing

• Online-only – the file is visible but takes no space; you need an internet connection to open it.
• Locally available – the file has been downloaded (e.g., after opening); it can still be automatically "slimmed down" when you free up space.
• Always available on this device – the file or folder is permanently stored locally and will be available offline as well.

How to enable Files On-Demand

In OneDrive settings, find the option related to saving space and downloading files on use. After enabling it, OneDrive will show file statuses and allow managing availability with one click.

How to manually free up space or force offline access

The “Always available” option

Right-click a file or folder and choose the setting that makes the data stored locally.

The “Free up space” option

When you finish working with a large folder, you can switch it to online-only mode. The data remains in the cloud, and only "pointers" to files are left on the drive.

Practical note

Online-only mode works best with a stable connection. If you often work on the go, set “always available” for the most important directories (e.g., current documents, templates, presentation files).

How to adjust settings to your work style

If OneDrive is your "command center," the key is to adapt features to your daily rhythm.

Strategy 1: small disk, lots of data

Choose only active project folders to sync, leaving the rest cloud-only. Within those projects, use Files On-Demand to download files only when you actually access them.

Strategy 2: field and offline work

Sync more folders but mark as “always available” only what’s necessary outside the office. This reduces the risk of missing files at critical moments while avoiding carrying the entire archive.

Strategy 3: order and fast search

Maintain a simple folder structure (e.g., Projects / Year / Client) and avoid very long paths. OneDrive works better when it doesn’t have to track thousands of tiny files in dozens of nested folders.

Common problems and quick fixes

File won’t download or keeps "spinning" endlessly

• Check your internet connection and whether you have transfer limits enabled.
• Pause and resume sync in the OneDrive menu.
• Log out and log back in to the OneDrive client (this often refreshes access tokens).

File conflicts after working on multiple devices

Usually caused by simultaneous editing of the same document. The rule helps: one person edits, others comment; or work in the web app with automatic co-authoring (which limits conflict copies).

Folder “disappeared” after deselecting in selective sync

This is normal – it has been hidden locally. Go back to "Choose folders" and check it again; OneDrive will restore the folder on your device.

Data work safety and hygiene

OneDrive provides tools for access control, version history, and recycle bin, but it’s worth adding good habits:

• Use multi-factor authentication on your account.
• Share files via permissioned links instead of repeatedly sending attachments.
• Regularly tidy up your shares, especially after finishing a project.

Brief note for those setting up a new workstation

If you install OneDrive fresh and simultaneously prepare software on a new Windows PC, remember that activation may be needed after reinstalling – at Key-Soft.pl you can buy a license and key for tools you get cheaply, including the Office suite.

Summary

Selective folder sync and Files On-Demand are a duo that lets you reconcile two opposing needs: keeping order and fast data access while not overfilling your disk. Start with selective sync, then fine-tune file availability in Files On-Demand. After one day of such configuration, it is usually hard to return to the “everything always downloaded” model.
