How can I replace the 'Folder' icons in the forum?

I installed the NTS KBee Template 6.0.1 to my Kunena 6.2.2 on a Joomla 5.0.1 platform.  My web address is:  4x4Forum.net  I am building the forum right now.  I would like to change the 'folder icons'.  Where can I find the file and/or folder that has the 'folder icons' so that I can replace them?  I have enclosed an image of the folder icons and highlighted them.  I have highlighted the large folder icons and I have highlighted some of the small folder icons.  I would like to replace both the large and small with different icons.  I have also uploaded a forum I previously to have built, that has different different icons.  Hopefully, it will help to understand what icons I would like to change.

Thank You & Respectfully,

Hello,

I noticed my images did not upload, so I have re-sized them, and hopefully, they will upload now.

Hi Tim,

Follow some below steps to add custom folder image for your forum.
1. From NTS KBee back-end. Click to the "Features" tab. Choose the "Icon Type: Images-legacy".
2. Create a file with named nts_kbee_custom.css in the css folder of your joomla template.
3. Copy and Paste below css rules to nts_kbee_custom.css file.

4. Copy / Upload your folder images to the "[root]/media/kunena/core/images/icons/" folder. (folder_nonew.png, folder.png, folder_nonew_sm.png).
5. Reload your website to view the changes.
Note: We have updated this code to the template package and we are improving some style before release new version.

Best regards,
