OneDrive Files On-Demand can show files that are not stored on your computer. Check in the app how cloud-only files are handled before you scan them; this page does not confirm that cloud-only files are scanned without downloading.
Marked duplicates are moved to the Quarantine Vault or your operating system's Recycle Bin / Trash, depending on the option you choose. Files in a OneDrive sync folder are synced, so moving or deleting them can also change your OneDrive account and other devices. Check the restore options in the app before you confirm.
Prism compares file contents, not just names or dates. Files with different names or timestamps but identical contents are grouped as duplicates. Review each group before you clean.
Yes. The preview screen shows duplicate sets side by side with thumbnails, file sizes, folder locations and modification dates. Nothing is removed until you confirm.
Prism scans files on your computer. This FAQ does not describe any upload of your files; if you are unsure, check the app and your OneDrive settings.
Large scans can take a while. If a scan is interrupted, reopen the app and check whether it offers to resume.
