What is the maximum number of files named Conf.test that can be in a project?

The maximum number of files named Conf.test in a project is not technically limited — you can have as many such files as you want if they are located in different directories. In a file system, files with the same name cannot coexist in the same directory, but in different folders — please.

Thus, the limitation depends on the project structure and directory organization, not on the file name itself.
