OneDrive on Windows should typically sync files in near real-time, meaning as soon as you make changes to a file or folder, it should start syncing those changes almost immediately, as long as you have an active internet connection.
However, if you are finding that files aren't syncing as instantaneously as you'd like, or if OneDrive seems to be lagging behind, you can follow these steps to ensure OneDrive operates in real-time as best as it can:
1. **Check sync status**: Look at the OneDrive icon in your system tray (the far right of the taskbar). If it is showing a white cloud, blue cloud, or swirling arrows, it's currently syncing files. A green check mark means it's up-to-date.
2. **Adjust settings**: Open your OneDrive settings by right-clicking the OneDrive icon in the system tray and choosing "Settings". Under the "Network" tab, if the upload rate is set to limit, reset it to "Adjust automatically".
3. **Give OneDrive high priority**: In Task Manager (which you can open by pressing Ctrl + Shift + Esc), look for OneDrive in the list of processes, then right-click on it and choose "Go to details". Now, right-click on it once more in the new list, select "Set priority", and set it to "High".
4. **Keep your device awake and online**: Make sure your computer doesn't go to sleep or offline as that will naturally interrupt OneDrive's syncing.
5. **Keep the OneDrive application updated**: Microsoft often pushes updates that can improve the functionality and performance of OneDrive, including its syncing capability. So make sure your OneDrive application is up-to-date.
While these measures maximize the real-time syncing of OneDrive, technical limitations and internet latency can sometimes introduce minor delays. However, under normal circumstances, OneDrive should sync files quickly enough that it seems like it's happening in real-time.
