Can multiple Windows 10 Pro Defender Exclusions be added in Group Policy or must they be input one at a time?

Windows 10 Pro Build 19044

My machine is a Digital Audio Workstation Laptop and I require to be able to prevent Windows Defender Antivirus from performing any actions on a large number of specific folders

In the Local Group Policy Editor, I know if I go to:

Computer Configuration > Administrative Templates > Windows Components >Microsoft Defender Antivirus > Exclusions

then Path Exclusions > Enabled > Options > Show Button

It brings up a "show Contents" box with a user editable area "Path Exclusions" with "Value name" & "Value"

This is where I become not so clear on what I must do...

If, for example I wanted to exclude a folder called "Folder 1" in Program Files I need to add the full path:

C:\Program Files\Folder 1 in Value Name" and then add 0 in Value to ENABLE the exclusion.

Is it correct that Windows Defender will then exclude Folder 1 and all files and sub folders from any real time protection and scans?

As I have around 30 folders that I wish to exclude (all music related), do I really have to enter each path one at a time or is there

a way to batch import them, maybe from a text file?

Many thanks

    Well I am disapointed that no one has made any suggestions especially as this forum was recomended to me by member of the Microsoft Answers forum.

    Poor show, very poor show.

    Thank you for your question and reaching out. I can understand you are having query related to Defender Exclusions

    If you have wildcard then all its sub folders will be excluded.

    For Example :

    1. C:\myfolder*\Data includes any file in C:\myfolder\Archives\Data and its subfolders, and C:\myfolder\Authorized\Data and its subfolders

    2.C:\Serv**\Backup includes any file in C:\Serv\Primary\Denied\Backup and its subfolders and C:\Serv\Secondary\Allowed\Backup and its subfolders

    Reference :
