from the path (or the current working directory when no directory can be inferred).

protected virtual FileInfo LocateFileFromDirectory(string filePathToResolve)
The file path to resolve.
For relative subpaths (e.g., "subdir/file.exe"), the directory component is inferred
from the path itself. If the directory cannot be determined, the current working
directory is used as a fallback. The method enumerates files in the inferred directory
(no recursion) and matches by filename using platform-appropriate comparison:
