Choose the Neovim configuration

Choose the Neovim configuration:  stable config or test config

------------------------------------------------------------
What to do? Where to install Neovim?

------------------------------
Install Neovim in a folder C:\UTILS\Neovim\

1. Download:
https://github.com/neovim/neovim/wiki/Installing-Neovim#install-from-download
Latest stable release

Assets 12:
nvim-win64.zip


2. Install (Windows):
https://github.com/neovim/neovim/wiki/Installing-Neovim
Unzip the package (nvim-win64.zip).

Run nvim-qt.exe
C:\UTILS\Neovim\bin\nvim-qt.exe

Create a stable configuration!

------------------------------
1)
First, rename the folders (stable config):
C:\Users\username\AppData\Local\nvim\
C:\Users\username\AppData\Local\nvim-data\

to
C:\Users\username\AppData\Local\nvim1\
C:\Users\username\AppData\Local\nvim-data1\

Note:  C:\Users\username\AppData\ , it is a hidden folder

You can insert a blank Neovim-stable-config.txt file  into both folders (for labeling purposes).

------------------------------
2)
Second:
Run nvim-qt.exe

Create a test configuration

Then, rename the folders (test config):
C:\Users\username\AppData\Local\nvim\
C:\Users\username\AppData\Local\nvim-data\

to
C:\Users\username\AppData\Local\nvim2\
C:\Users\username\AppData\Local\nvim-data2\

------------------------------------------------------------
for example
I am currently using a test configuration:

C:\Users\<username>\AppData\Local\

nvim  (Symlink to folder nvim2)
nvim1
nvim2

nvim-data  (Symlink to folder nvim-data2)
nvim-data1
nvim-data2

INSTRUCTIONS

------------------------------------------------------------
Create a symlink:

------------------------------
Windows Command shell
MKLINK

https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/mklink

An A-Z Index of Windows CMD commands:
https://ss64.com/nt/mklink.html

MKLINK [[/D] | [/H] | [/J]] LinkName Target
   /D     Create a Directory symbolic link. (default is file)
By default, only Administrators can create symbolic links.

------------------------------
CreateLink
http://multicommander.com/docs/customcommands_list#mc.utils.createlink
MC.Utils.CreateLink
LNKTYPE   1 = Hardlink, 2 = Junction, 3 = Symlink, 4 = Shortcut

------------------------------------------------------------
http://forum.multicommander.com/forum/index.php/topic,1345.msg4769.html#msg4769

To create Symlinks you must be admin.
You can add "ASADMIN" and you will get a UAC dialog, or you can start MC as admin.

LNKTYPE   3 = Symlink
MC.Utils.CreateLink ASADMIN LNKTYPE=3 LNKSRC="<new source folder>" LNKTRG="<existing target folder>"

<new source folder>  Must not exists.
<existing target folder>  It exists.

UAC dialog is shown and MCAdmin (Admin helper Process) is starts
SymLink folder is created and points to existing target folder

Before using this script, you should make a backup of the Neovim config folder.

Be sure to "exit" Neovim, and only then run this script!
As I remember, Neovim config folder was deleted a couple of times...
