How to make Dropbox files online-only by default in Windows 11

Making Dropbox files online-only by default in Windows 11 saves local disk space by keeping most files in the cloud.

Online-only files act as placeholders, appearing in your Dropbox folder but not taking up storage space until you open them. This feature is especially helpful for managing large archives or old projects.

This setting ensures new files you save to Dropbox are automatically set to online-only, preventing your computer’s drive from filling up unexpectedly. You can always switch files back to be available locally if needed.

⚡ Quick Answer

To make Dropbox files online-only by default in Windows 11, click the Dropbox icon, go to Preferences, select the Sync tab, and choose “Online-only” from the “New files default” dropdown. This ensures new files are saved to the cloud first, saving local storage.

Dropbox online-only default on Windows 11 saves hard drive space. This setting means new files you add stay in the cloud and only download when you open them, keeping your computer's storage free. You manage your files without manually changing each one.

Find the Dropbox Icon

💡Tip
The Dropbox icon in your Windows taskbar shows your Dropbox files. This icon typically appears as a small blue cloud or the Dropbox logo. If you do not see the Dropbox icon, click the small upward-pointing arrow to reveal hidden icons.

Manually Changing Files to Online-Only

Open Your Dropbox Folder

Your Dropbox folder, located within Windows File Explorer, stores all your synced files. Making Dropbox files online-only by default in Windows 11 saves storage space on your computer.
