What's the best iOS app for accessing files from a Windows computer on an iPhone?

Microsoft OneDrive is a cloud storage app that provides robust solutions for users needing to bridge the gap between Windows computers and iOS devices. For individuals who work across multiple platforms, such as professionals or students, the app enables direct access to files stored on a Windows PC directly from an iPhone. This is facilitated through automatic syncing, where files saved to the OneDrive folder on a Windows machine instantly become available on the iOS app. Specific features like Files On-Demand help manage storage by allowing users to view online-only files without downloading them, which is useful for iPhones with limited space. In real-world scenarios, a construction manager could upload CAD files or PDF blueprints from a Windows 11 laptop and review them on-site using an iPhone, ensuring project details are always at hand. However, some limitations exist; reviews indicate that the iOS interface can feel clunky at times, and users report occasional difficulties when trying to upload files directly from other apps like Mail. Despite this, OneDrive's integration with Microsoft Office apps supports editing documents on the go, and features such as automatic photo backup add value for personal use. The app's cross-platform reliability makes it a solid choice for maintaining workflow continuity, though occasional UI refinements could enhance the mobile experience.
