## Number-Based Reference System

The bot uses a number-based reference system for ease of use:
1. User runs `!dateien` or `!ordner` to get a list
2. Bot stores the list internally for the user
3. User can reference items by their list number
4. Numbers are valid until the user runs a new list command

This allows simple commands like:
- `!datei 3` - Show details for file #3
- `!download 1` - Get download link for file #1
- `!dateien 2` - List files in folder #2
- `!verschieben 1 3` - Move file #1 to folder #3
