  dir.create(source_conn)
  write.csv(mtcars, file.path(source_conn, "mtcars.csv"))
  write.csv(iris, file.path(source_conn, "iris.csv"))

  # Get file path for mtcars.csv
  source_conn_path(source_conn, "mtcars.csv")
#> [1] "data_dir/mtcars.csv"

  # Clean up
  unlink(source_conn, recursive = TRUE)
