A Microsoft file hosting and synchronization service.
Hi, let me help you.
Please go to your OneDrive web app. you can download the desktop app from ther.
If you go to onedrive.com and sign in with a Microsoft account, that's the "OneDrive web app" — it lets you view/manage your files in the browser.
From there, you'll usually see a "Get the apps" or "Download" option (often in the bottom-left corner or under a settings/gear icon) that links to the OneDrive desktop app installer for Windows.
