Modify upload provider with custom path

Dear @sunnyson and @Umbert_Pensato .
I am trying to upload a1.zip file of entryA1 in Collection A (that is Want to upload a1.zip to /public/upload/CollectionA/A1…)

Kindly you explain that
" To modify the Upload model:

Copy file →
./node_modules/strapi-plugin-upload/models/File.settings.json
to:
./extensions/upload/models/File.settings.json and edit it here.

It will overwrite the original model of Upload plugin."

but ./node_modules/strapi-plugin-upload/models/File.settings.json only have json definitions.

no place to add code
const modelName = ‘articles’;
//…
const requestURL = http://localhost:1337/${model}/;
//…
formData.append(‘path’, ${model}/uploads);

Sorry for it if I miss undertstand you r explonation…
Could you tell me a liite more about it ? how to ?
thanks in advance…
