One of the best features of OneDrive in Windows 8.1 is that even if you have a terabyte of files up there in the cloud, it isn’t going to automatically try to download them to every device that you use. The files only download on-demand… but what if you want to make them download all at once?
You can right-click on any file or folder inside of your OneDrive and choose whether to make it available offline, or to make it online-only, which will remove your local copy but keep it up there in the cloud.
But to change this setting to be the default, you’ll need to take a quick trip into the OneDrive settings, which can be found by right-clicking on the OneDrive tray icon and choosing Settings.
Once in here, you can check the box for “Make all files available even when this PC isn’t connected to the Internet”. This will download everything all at once, and make sure that all future files that get placed into OneDrive from any device will get downloaded.
On the other hand, if you have way too much stuff in your OneDrive and you don’t need it to be available on the PC that you’re working on, you can remove all the files from your local system and make them available online-only by clicking the “Make all files online-only” button.
