Installed 2 programs for file recovery. But both are not for network drive access in the free version. Need a paid version for network drive access.
Realised now what I did years back. I was running out of PC disk space more than 10 years ago, before I bought the NAS. I copied some of the photo big folders to DVD disks and then deleted these big folders from the PC hdisk.
Years later after getting the NAS, I copied the hdisk photo directory to the NAS. Forgot to copy the folders in DVD to NAS!
Very glad that I still have the Japan holiday photos. My wife would use that to demand another Japan holiday if the photos and memory were all gone! Ha.
One action for me to follow up. How to enable the recycle bin in My Cloud just in case one day I deleted some important files by mistake in the NAS?
