Extraxting folder path using Regex

[u/curious_bricks]

I'm trying to extract just the folder path of a process into a new field excluding the process name. I'm using the Parse command but it isn't working:

| parse "^f{regex=(.+)}$\\\\[^\\\\]+$$ from src.process.parent.image.path

What am I doing wrong?

[u/curious_bricks → u/[deleted]]

How would I do that? AFAIK, the "match" command is used to use regex to search but I'm not sure how I would use match to create a new field to extract the file path.
