How to Find Duplicate Files in OneDrive Without Downloading Them First?

Cloud storage management becomes considerably more efficient when there is a way to find duplicate files in OneDrive without downloading them first, since pulling every file locally just to compare contents wastes both bandwidth and local disk space unnecessarily. The manual approach through File Explorer requires OneDrive sync to be active and files to be at least partially cached locally, after which sorting by Name or Date Modified and manually comparing file sizes helps spot obvious duplicates — though this method misses duplicates with different filenames entirely. Searching for files containing a specific computer name suffix catches duplicates created through sync conflicts across multiple devices, but this only addresses one specific cause of duplication rather than the full range of redundant files accumulating in storage. SysInfo OneDrive Duplicate File Finder works directly with files stored in the cloud, scanning content, size, and metadata without requiring files to be downloaded to the local machine first. The Scan All Folders feature performs a thorough sweep across the entire account, and Smart Grouping automatically categorizes detected duplicates by name, size, content, and file type for easier review. Compatible with all versions of Windows, macOS, and Linux.
