Hello,
I’m new to processing with Python and I want to access subfolders in my data folder with my processing project. If I loop through the folders with os.listdir(), only see the main.pyde. I’ve already tried dataPath and dataFile but without success.
My current folder structure is:
main.pyde
sketch.properties
data
- Subfolder1
- Subfolder2
- Subfolder3
Kind Regards,
Corné

Hi,
Welcome to the forum! 😉
I have this folder structure :
```auto
.
├── data
│ ├── folder_1
│ └── folder_2
├── sketch.properties
└── test_python.pyde
```
I tested this code :
```auto
import os
def setup():
print(os.listdir("./data"))
def draw():
pass
```
And it works :
```auto
['folder_1', 'folder_2']
```
But be sure to save your file before running, it was not updating in my case so at the beginning I thought it was not working properly.
And also your error might be that you omitted to put the `data` folder inside the path, I know that in Processing Java the relative path is in the data folder but maybe in python it’s not the case…

Just pass an empty string "" to dataPath(): dataFolderPath = this.dataPath('') + '/' print dataFolderPath … or to dataFile(): dir = this.dataFile('') dataFolderPath = dir.path + '/' print dataFolderPath However, if you need all files within the sketch’s “data/” folder, like all images for example, you can use listPaths(), passing the “data/” folder path + a string w/ all desired “extensions=,”: sunglasses PICS\_EXTS = 'extensions=,png,jpg,jpeg,gif,tif,tiff,tga,bmp,wbmp' dir = this.…
