# Source.paths

## Example

```python
from lsdtools import Source

Source.file(folder="data", patterns="*.csv").paths()
# → ['data/a.csv', 'data/b.csv']
```

## Notes

Only file sources resolve to paths; a [`sql`](/docs/api-source-sql) source (or any kind that
does not read files) returns `[]`. This is the resolved list — a `folder` + `patterns` source
is expanded to the files the glob currently matches.
