Onedrive sync file problem

Question

The files I synced to Onedrive suddenly all disappeared today!

Answer 1

Dear Thạch Thất Độ，

It has been several days since I have received a reply from you. Have you submitted your OneDrive data loss related content to the above website?

I understand that you want to restore deleted files and I understand the inconvenience caused by the deletion of your files. At this time Community Tech Support can only provide assistance with software technology, for your OneDrive cloud data is kept in highly encrypted data centers, which is something that community members cannot easily access.

Nonetheless, if your OneDrive was synchronized with a local computer, your files will be saved on the computer's hard drive for some time, and despite the deletion, the data will be saved in a hidden partition (which is gradually cleaned up over time), so it's a minute-by-minute process in the event of a data retrieval incident, and following this, I recommend that you submit your feedback as soon as possible. This will help the technician to be able to search their file history as soon as possible.

I look forward to hearing from you. Thank you.

Best Regards,

Kiki.

Thank you for your reply, I've followed the method you provided here but it didn't work, I've confirmed on my cloud including the recycle bin but nothing, are there any other options available to you here?

Dear Thạch Thất Độ，

Thanks for using Microsoft products and posting in the community. 

I understand that the files you synced to OneDrive disappeared. I understand your urgency and will do my best to help you.

You can try logging into the Personal Cloud Storage – Microsoft OneDrive using your phone to see if the files still exist in the cloud. Sometimes due to device or network issues, the files may just disappear from your local device but still be saved in the cloud.

And you can check the recycle bin to see if the file still exists. If the file is in the Recycle Bin, you can restore it. And you can try to find the lost files according to the following steps.
