Where to recover files and folders

Where to recover files and folders after deleting content
The disk has not been used since

More information is needed. From where did you delete the files or folders? Your computer? The My Cloud? Some other location?

The single bay My Cloud does not have a “recycle bin” option so any file or folder you delete will be difficult to recover using third party data recovery software.

If you deleted files from your computer then the question is how did you backup that information to the My Cloud. Did you backup or sync your computer to the My Cloud? If so using what software?

Check that software for information on how to restore or recover files.
