OneDrive is a cloud-based storage service that comes with your Microsoft account. OneDrive is integrated into Windows 10 where you can view, browse, upload, and share the files you saved online to OneDrive from any PC, tablet, or phone.
Once you set up OneDrive and have it running, OneDrive will automatically sync your chosen files and folders with your PC.
Starting with the Windows 10 Anniversary Update, you can manually pause syncing of files and folders on OneDrive as needed.
By default, Windows 10 will automatically pause sync when the device is on a metered Ethernet or metered wireless network.
This tutorial will show you how to enable or disable automatically pause OneDrive sync when on metered network for your account in Windows 10.
