I was working in an Excel file sitting on mycloud drive away from home where the server box is on a wifi network and the network dropped do it would May allow me to save the file kept saying document not saved so then I saved a copy to my desktop reopened windows explorer and cut and paste the copy file into the my cloud drive. Then went to delete the older version and rename the updated file without the copy title. Somehow in this process both files disappeared completely. The old version did not end up in the recycle bin it looks like it was permanently deleted and the new version just disappeared 
it was a very important file and I now need to try to recover it one version or another urgently
