How to compare the contents of two resource files (*.res)?

I am working on a vb project which uses a resource file (*.res) to map between two values.

Now I need to compare two resource files (existing one and the edited one), I have "Beyond Compare" and "Win-Merge" software to compare .. but the RES file gets opened only in Visual Studio and the contents of the RES file can't be copied all at once .. and as it uses some script (or e开发者_如何学Cncryption) on its contents .. it can't be opened with any other editors

now because of which I have to make a manual comparison which is hectic task .. file size is too big .. the alternate was to use file compare software where as they don't support this extension of file ..

Can you please help me with extraction of the contents of the file?

Download a resource editor (like ResEdit) and convert it to a resource script (.rc) file.

A resource script is as good as a text file, can be copied and edited using notepad

Two files can be directly compared in beyond compare.
