The regex you’re using is pulling out the last folder of the related folder, so it’s make sense that it appears somewhere in your list. I think I’d rather approach this slightly different, and that is to remove the folder of your index file, and then group on the rest of the folder.
```dataview
LIST
rows.file.link
WHERE startswith(file.folder, this.file.folder)
GROUP BY regexreplace(file.folder, this.file.folder + "\/", "")
```
How does that look to you? This will display all sub-folders as separate items, and keep sub-folders connected with their parent folders. It’ll start the list with any files residing in the current folder.
Bonus tip: How to present code properly in a forum post
If you want to showcase either markdown, or code blocks, or dataview queries properly in a forum post, be sure to add one line before and one life after what you want to present with four backticks, ````. This will ensure that any other backticks (like for code blocks) is properly shown.
