The projects resource file is generated by the IDE wizard, and is not intended to be modified. To add additional resources to your project, create a separate resource file with a unique name that does not conflict with either the project or any of the unit names. Then to add the resource file to Delphi, simply add the following line to any unit file in the project: {$R MyRes.Res} (where MyRes.Res is the name of the resource file). To add the resource to Borland's C++ Builder, add the resource from the project manager.
