A Microsoft file hosting and synchronization service.
Dear respected John,
I'm sorry to hear that you've had a negative experience with OneDrive. However, Microsoft does not delete files from a user's local computer without their permission. It is possible that you may have accidentally enabled the OneDrive feature that automatically backs up your files to the cloud. For reference: Sync files with OneDrive in Windows - Microsoft Support
If you would like to restore your files back to your local hard drive, you can do so by downloading or directly copy them from the OneDrive sync folder showing in left bar on the File Explorer and saving them to your computer.
I appreciate your patience and understanding and thank you for your time and cooperation.
Sincerely,
Mia | Microsoft Moderator
