Hide .svn folders

[HeiWoMa]

Hi,
I have a bunch of folders under control by TortoiseSVN. The settings are located in folders with the name '.svn'. Can I hide these folders?
I need to have Menu: View -> Show -> Show hidden files checked to see hidden files. Only .svn should not shown.
Is there any secret to do it?

You could define a custom filter (Alt+Y) to exclude them from view.

Thank you,
that goes in the right direction. A fast test works as wanted. Now I need to go a bit deeper in it.
