What is the correct name for the repository?

Question

git

I'm working on a project
I did something, and now there is an inscription

Merge branch 'master' of https://github.com/hello-world00/VK-messages-parser/

I also realized that I chose the wrong architecture. By changing it, you can reduce the number of queries to the database.
I feel like I chose the wrong folder, repository, and file names.
The project should consist of 2 parts:
1) downloading dialogs and writing to the database
2) Interface for viewing dialogs (REST API)
Now the questions are:
1) How do I correctly name files, folders, repository? After all, he downloads and extracts data from there.
2) Should I delete the repository and create a new one because of the wrong architecture and that inscription?
