Hello Daniel,
If I understand correctly, the folder structure is static, it’s just that the file name could be something different? If that’s the case, I didn’t find anything that will do that automatically, I had to make something myself that would do Directory.GetFiles and then parse the output of that to only return the files that matched a specific regular expression. Unfortunately the GetFiles method uses its own quasi-regex format that I wouldn’t suggest even bothering with. Just be sure to remember that Windows files are not case sensitive when you search for specific filename conventions.
