How to delete all tracks in pcbnew?

When i update my Eeschema design with a new version. then I update to my pcbnew. Becase my update changes too much components, so i want delete all tracks in the pcbnew before. I wonder to know is there a quick method to delet all tacks of my pcbnew?

select everything with block selection and then use selection filters to only select traces. ( right click -> select -> filter selection) After that just use the delete key.

thanks, that’s wonderful. :+1:

Block select ???

Use:
Pcbnew / Edit / Global Deletions
