# `GSFeaBlock.filePath`

*Instance Property*

A file path relative to the `features` directory in a Glyphs Package file.

## Declaration

```swift
var filePath: String? { get set }
```

```objc
@property (strong) NSString * filePath;
```

```python
filePath() -> str
setFilePath_(filePath: str)
```

## Discussion

Unset when the block does not correspond to a file. Before saving the document, this value is updated to match the new file path in case a change is required. A change might be required when there are multiple features with the same name. In that case, the first block might be written as `calt.fea` and the second as `calt.2.fea`.
