Hello everyone,

I have this very stupid question: How can I remove folder names from the output given by `readdir()`

Lets say I have the following folder structure:

```julia
folder1/
|_ file1
|_ file2
|_ file3
|_ folder2/

```

I get then

```julia
julia> readdir()
4-element Vector{String}:
 "file1"
 "file2"
 "file3"
 "folder2"

```

Is there a way to exclude all folders from the output?

Many thanks in advance,  
Olivier

```julia
filter(!isdir, readdir(; join=true))

```

perhaps.

NB:  
for reference, [here](https://github.com/JuliaLang/julia/issues/29223) it is shown a good complement to Kristoffer’s solution to be able to display long file lists:

```julia
filter(!isdir, readdir(; join=true)) |> x -> show(stdout, "text/plain", x)

```
