Cannot Display All Folders on NAS in File Explorer

MountainBoomer 1

I've recently been through the "Network Attached Storage can't be seen/mapped in Windows 10" ordeal and have it resolved...mostly. I have a Western Digital MyPassport 4TB external SSD connected as NAS via USB to my Asus RT-N66R router. Accessing the router directly using a browser interface, I can see all 4 directories on the NAS. However, using Windows Explorer, I can only see 3 of the 4 directories. I've mapped the NAS as Z:\ and 3 folders are visible. If I type the path (e.g., \RT-N66R\MyPassport_4TB\Folder Name) into the bar at the top of the Windows Explorer screen, I can then see that directory and all subfolders...but I can't map to it. I experience the same phenomenon on two separate computers I've tried, both running Windows 10.

As an interim solution, I'm able to create a shortcut for that "invisible" folder on the desktop using the full path above, but using this is cumbersome compared to being able to see all 4 folders simultaneously within Explorer.

I can't figure out why 3 directories would show up but not the fourth. Suggestions?

Before going further, I would appreciate your help in clarifying the following situations:

a. What's the OS version of your windows 10? 1909 or 2004?

If I type the path (e.g., \RT-N66R\MyPassport_4TB\Folder Name) into the bar at the top of the Windows Explorer screen, I can then see that directory and all subfolders...but I can't map to it.

b. What's the exact error message when you cannot map the path?

I experience the same phenomenon on two separate computers I've tried, both running Windows 10.

c. How about other OS like windows 8/8.1? If all windows machines have such phenomenon, you might need to contact NAS support for further help.

a. Currently it's 1909.

b. I already have the network drive mapped as I want it. I just can't see the fourth folder. If I try to map the specific folder as a separate network drive, the error is "Windows cannot access _. Check the spelling of the name. Otherwise, there might be a problem with the network." Error code: 0x80070035, The network path was not found." However, if I type the exact same path into the bar at the top of Windows Explorer, the folder is found and functions properly (i.e. I can see all the subfolders and access them).

c. I only have two machines; both Win10.

Thanks for your updating. Have you moved the fourth folder to other subdirectories to do a test? Will the folder be visible in such situation?

I have not...each folder is set to auto-synchronize separately and I'm hesitant to change the hierarchy as it may interfere with proper synchronization. Can we try this after other possibilities have been explored?
