How to Turn Off OneDrive Sync and Delete Files?

If you want OneDrive completely out of your startup, head to Task Manager > Startup Apps, find OneDrive, and disable it. After a restart, OneDrive won’t automatically start. This way, you can manage your files without it interfering.

To stop the sync, you can either unsync your OneDrive in the settings or uninstall it if all your files are already downloaded on your PC. This way, deleting from OneDrive won't affect your local files.

A solid way to manage this is to store all your OneDrive files locally first. Once that's done, unlink OneDrive using the app's options. Then, you can safely delete files from the OneDrive website without worrying about them disappearing from your PC.

You could log out or disable OneDrive altogether, then access it through a browser to delete files. That should help keep your PC files intact!

You might want to try deleting files from the OneDrive web interface instead of the app. Just remember, if you haven't unlinked your PC from OneDrive, deleting files will remove them from everywhere.
