How to identity used clips

I'm new to HitFilm Pro. I've come from another NLE which I left behind due to high upgrade costs which I couldn't justify as a hobby user. So I thought I'd give HitFilm Pro a go.

I've imported a lot of videos (over 200) and still pics (over 1000) into the media folder and only used a small amount of them (maybe 30) in a short home video. How can I tell/see/identify which clips in the media folder are used in the editor timeline so I can remove superflous media from the media folder? I can't seem to detect any markers on the thumbnails nor find anything in the user manual about it. The previous NLE had a green tick in the thumbnails of used clips.
