Windows 10: How to remove all folders of the 2. hierarchy which have only 1 subfol

A folder (1) contains an uncertain amount of sub folders (second hierarchy). Each folder in the 2. hierarchy can contain at least one item (folder or file) or more. When a folder of the second hierarchy contains only one subfolder (no more items) this subfolder shall be remove (without its content) so that the subfolder (third hierarchy) of the folder of the second hierarchy becomes a subfolder of the second hierarchy.

How could I do it without any knowlegde of programming and such automatically with as less as possible interactions?

Each subfolder of the third hierarchy contains at least one item (file or folder) and has an uncertain name, the name can be the same one as its superior folder.

For example:
I:\folder 1\folder 2\folder 3
folder 2 has only one subfolder (no more items), "folder 3", therefor folder 3 shall go to:
I:\folder 1\folder 3

For example
I:\folder 1\folder 2\folder 3
I:\folder 1\folder 2\file.xxx
folder 2 has one subfolder and one item, therefore it keeps where it is

My desktop icons dissapeared from explorer view but not in desktop

The desktop (background) is comprised of these objects:

1. Files and folders in user's desktop folder

2. Files and folders in common or Public\Desktop folder

3. Shell objects implemented in per-user Desktop namespace

4. Shell objects implemented in per-system Desktop namespace

Whereas the folder view shows only items in #1 above. To see the consolidated view of complete desktop namespace, in File Explorer View tab, click Navigation pane, and enable Show all folders.

This changes the hierarchy in navigation pane to:

Desktop

->OneDrive

->This PC

->Libraries

->Removable drives

->Network

->Homegroup

etc..

So, clicking Desktop which is at the top of the hierarchy will show the consolidated view, populating entries from all the 4 locations specified above.

 

File sharing without Homegroups

I have 2 Windows 10 computers and one windows 8.1 (can't update it to windows 10, because it has a Micro SD reader that doesn't have drivers for WIn 10).

All 3 machines are Ethernet Cat5 connected

Homegroup support is being withdrawn for Windows 10.

With no Homegroup, I can't access anything on the Win 8.1 machine that is not in the Users/Public hierarchy from either Win10 machine.

The laptop Win10 computer thinks there is a Homegroup, but it can't see any other Homegroup machines. Nothing happens when I click "View or print the Homegroup password" or "Change the password", and when I try to have it leave the home group, I get the
error message "Windows couldn't remove your computer from the Homegroup"

The samelaptop sees only the Win8.1 machine on the network. It can only access the /Users/Public hierarchy on the Win8.1 machine. However, both the other machines can see the laptop.

The primary login on both Win10 machines uses the same name and password.

There is a Microsoft community conversation which says that deleting C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking\idstore.sst allows me to exit the home group. Leaving aside the fact that there is no
AppData in this hierarchy, there is no idstore.sst file anywhere in the
c:\Windows hierarchy on the laptop. There are idstore.sst.new and idstore.sst.ldk files. Deleting both of these files, and then rebooting the machine, changes nothing.

SO, what do I need?

1) How do I set up my network so that I can share files between all 3 computers without having to do everything through the Users/Public file hierarchy?

and

2) How do I remove my laptop from a Homegroup that nobody else can access?
