# Study Materials

> How to browse, view, and download study materials shared by your teacher on Lena.

Your teacher uploads study materials — documents, PDFs, images, videos, and
other files — organized in folders within each course. Here's how to find and
use them.

<Note>
  **Before you begin:** You need to be enrolled in a course. See [Joining a
  Course](/students/joining-a-course).

## Downloading materials

To download a file for offline access:

1. Tap the file to open it
2. Look for the **download icon** (usually an arrow pointing down)
3. The file will be saved to your device's downloads folder

<Tip>
  Download materials when you have a good internet connection so you can study
  them offline later — especially useful before exams or in areas with
  unreliable connectivity.
</Tip>

## Folder structure

Your teacher organizes materials into folders for easy navigation. A typical
structure might look like:

```
📁 Week 1 - Introduction
  📄 Lecture Notes.pdf
  📄 Introductory Slides.pptx
📁 Week 2 - Core Concepts
  📄 Chapter 2 Notes.pdf
  📄 Practice Problems.pdf
📁 Past Questions
  📄 2024 Exam Questions.pdf
  📄 2023 Exam Questions.pdf
```

<Note>
  You can't create, rename, or delete folders or files — only your teacher can
  manage the study materials. If something is missing, ask your teacher to
  upload it.
</Note>

## Troubleshooting

<Accordion title="A file won't open">
  * Check your internet connection - Try refreshing the page and tapping the
    file again - The file format might not be supported by the built-in viewer —
    download it and open with a compatible app on your device
</Accordion>

<Accordion title="Materials are loading slowly">
  * Large files (videos, high-resolution images) take longer to load - Try
    switching to a faster network (Wi-Fi instead of mobile data) - Download the
    file for faster access next time
</Accordion>

<Accordion title="I can't find the materials my teacher mentioned">
  * Check all folders — the file might be in a subfolder - Ask your teacher
    which folder it's in - The teacher may not have uploaded it yet
</Accordion>
