+# Import from folder
+
+If you have a folder full of modules that you want to import from your app, than
+the trick from [Multiple python files](https://github.com/blackary/sis-tricks/tree/main/multiple-python-files)
+won't work -- you can't just `put` a whole folder to the stage and then import from it.
+
+Instead, you can create a zip folder, put _that_ to the stage, and then import from
+that zip directly.
+
+1. Create an app with the code from streamlit_app.py
+2. Put several python modules in the `utils` folder, or another similar
+3. Zip the utils folder
+
+   ```sh
+   zip -r utils.zip utils/*.py
+   ```
+
+4. Create the app in SiS, either through the web UI, or through the snowcli
+
+   ```sh
+   snow streamlit create --file streamlit_app.py GREAT_NAME_FOR_MY_STREAMLIT
+   snow streamlit deploy --file streamlit_app.py GREAT_NAME_FOR_MY_STREAMLIT
+   ```
+
+5. Upload utils.zip to the stage
+
+   ```sh
+   snow stage put utils.zip GREAT_NAME_FOR_MY_STREAMLIT_STAGE
+   ```
+
+6. Profit!
