How do you update a download with a newer file ?

[WTE_Galway]

I wish to replace one of my template layers in the download section with a slightly newer version of the layer.

Is there any way of updating the existing download?

Alternatively, if I upload the updated version how do you delete the outdated one ?

Upload the new one, send one of the staff members a PM telling which file you wish to have deleted.
