Editing Content Type Custom Forms in SharePoint 2010

Question

We have migrated MOSS 2007 sites to SharePoint 2010 using Database attach-detach method.
Every list has 1-2 content types and each content type has its own New, Edit and Display forms.
I tried opening these pages in SharePoint Designer 2010 but looks like there is no way of accessing these files.
There is a Forms section on the Content Type Settings Page, and I can see the links, when I click on the link they change to textboxes. I wanted to check if there is a way to edit these files. Any pointers on how to create custom forms for Content Types without using VS would help.

Answer 1

We can edit these files.
I could reach to these files by using SharePoint Designer.
File-> Pages ->Open (on the right pane)->Lists.
When a list is opened, we can see the custom forms for the content types and from there we can open these files.
