How to bundle any file into your .cab

[Webmaster]

There is a special feature which will help you to support affiliates. When you make a version of the toolbar to be distributed by an affiliate, you need to put there a file named affid.dat with a special assigned ID.

When you say "you put there"... What is "there"?

You can add/remove any file you need to/from your .cab file. You should go
"Toolbar->Bundle files with the toolbar->Add file to bundle with the
toolbar..." menu and select a file to add.
And you can manage files by clicking "Manage list of bundled files...".
