Ignore folders from current project/repository

Hi,

I am new to PTC Integrity Source Control.

Am used to Git/Svn, wherein I can specify an ignore file to ignore specific files/folders providing a pattern.

In my current project there are some files which are already checked in and as a part of restrucring, I want to ignore specific folders (obj, bin folders of a Visual Studio project). I am unable to figure out how to do it.

I tried the Sandbox -> View -> Non Member, but unable to see any items listed there.

Can anyone guide me as to how to ignore folders from an existing repository?

Thanks,

Chandu
