Windows 8.1 comes with the OneDrive service built-in but Windows 7, since it was created a couple of years ago, wasn't designed with such tight OneDrive integration in mind. However, this doesn't mean that you cannot use this service in Windows 7 to synchronize your files across devices and computers. Microsoft offers a very good application for this operating system and, in this tutorial, we will share how it works.
How to Download & Install the OneDrive Desktop Application
In order to get the OneDrive desktop application, you'll have to download it from Microsoft's web site. Visit the OneDrive download page to download the application.
Press "Choose your Device" and select PC | Mac.
On the bottom of the page, click "Download OneDrive for Windows" and save the OneDriveSetup.exe file somewhere on your computer, so that you can easily find it and run it.
Then, run OneDriveSetup.exe to begin the installation.
Click Get started to begin the process of configuring and installing your desktop OneDrive application.
In the next window you have to sign in with your Microsoft account. Type your email and password and then click Sign in.
By default, the OneDrive folder will be installed in your user directory, at the following path: "C:\Users\Username\OneDrive". For most users this will be an acceptable arrangement. If you've got a better place in mind, click Change.
Browse through your file system to locate a better place for your OneDrive folder and click OK.
Once you've made your selection, or if you were happy with the default, click Next.
You now get the option to select which folders in your OneDrive you want to sync to your computer automatically. If you want everything synced, select "All files and folders on my OneDrive", otherwise select each folder you want to sync. Click Next to move along.
Select whether or not you want to enable the fetch feature for this computer. This allows you to browse through your computer's file system from other computers connected to your OneDrive to fetch files you may have neglected to store on the OneDrive. You can learn more about this feature, from this guide: How to Fetch Files Remotely from Your PCs Using OneDrive in Windows.
Click Done when you're ready.
Once the installation is complete, you'll notice a cloud icon in your system tray.
