Nuxt3: Exclude files in /pages

Question

how can I exclude some files in /pages? I want to write page-level components just next to the page [page-name].vue like /[page-name]/cpnt/onlyInThisPage.vue

I got warning:

                                                                 4:53:37 PM
[4:53:42 PM]  WARN  Sourcemap for "[paths]/pages/index/context.ts" points to missing source files
