Bulk creation of new custom file associations in Windows 10

Hello, this is my first post here. Actually I posted this first in Microsoft Community Forums, but I was kindly instructed to post my query here instead.

I use a lot of configuration files for a certain program, and when I say a lot I mean a LOT really... over 100 different file extensions, but which are actually all plain text files. I use Notepad++ to edit them, and opening them is not too much of a problem as I have the "Edit in Notepad++" option enabled in the drop down menu for all files.

What I would like is to be able to display a description of the contents of each file directly in Windows Explorer... Since they are all unknown extensions for the operating system, the explorer only indicates "XXX File" with XXX being the different extensions.

In earlier versions of Windows, I could have easily changed this... But with Windows 10 I find it impossible to get a persistent result, as I tried different ways and many times the extension descriptions are reverted to their default values, sometimes the association to open with Notepad++ is lost, sometimes the icons change to Notepad++ and sometimes not, etc etc....

I would like to know what is the right way to do it. So far I have tried through the elevated command line with assoc and ftype commands, I have manually edited the system registry, in HKCU and HKCR, I have tried with a script in PowerShell, etc...

I have noticed that once a file association defined by me gets "broken" in any way, the only definitive way to fix it that I found was by using the FileTypesMan program.

Also, I understand that the editing of file associations should now be decided and executed by the user and not automatically by an application, but I find it very tedious to have to do it manually more than 100 times? I would like to do it in an automated way, i.e. via a script or batch file. Unfortunately FileTypesMan has no option to edit in bulk.

Please note that I am not an IT professional, just a final user with a little more knowledge than the average (say).

Any suggestions would be much appreciated!
