where i find the nippy files

It seems like you might be referring to "nippy" files in the context of data processing, file formats, or software. However, "nippy" isn't commonly recognized as a specific term in programming or data management. If you can provide more context about what you mean by "nippy files"—such as the type of files, their purpose, or the software you are using—I would be better able to assist you in locating or identifying these files.
