How do you erase blender files that you do not want

What I am wondering is how I can erase .blend files I no longer want, last time I tried I erased stuff I did not want to. Thanks ahead of time.

umm… Delete them in you file browser application? Drag them to the wastebin…

I don’t think I understand.

Open the filebrowser, mark the blendfile, press x.
