I’m having difficulty finding the best way to manage external data files in a module I’m writing.

Say we have a module `Foo` that we add to our local packages through `Pkg.clone("https://repo.com/Foo.git")`. In the repository lies a folder `input` with a data file `data.csv` inside it.

What is the best method to load this csv file into a dataframe in my module?

Currently I self-reference the module’s local path using `Pkg.dir` like so:

```julia
module Foo
using CSV, DataFrames

loaded_data = CSV.read(joinpath(Pkg.dir("Foo"), "input", "data.csv"));
end

```

The call to `Pkg.dir("Foo")` seems a bit brittle here, but it functions for the moment. Is there a better way to do this though?

Try

```julia
joinpath(@ __DIR__ , "..", "input", "data.csv")

```

Perfect! The [@\_\_DIR\_\_](https://docs.julialang.org/en/stable/stdlib/file/index.html#Base.@ __DIR__ ) macro was exactly what I was looking for. Thanks.
