# init(style:allowedUnits:spellsOutZero:includesActualByteCount:locale:)

Initializes a byte count format style.

```
init(style: ByteCountFormatStyle.Style = .file, allowedUnits: ByteCountFormatStyle.Units = .all, spellsOutZero: Bool = true, includesActualByteCount: Bool = false, locale: Locale = .autoupdatingCurrent)
```

## Parameters

`style`

The style of byte count to express, such as memory or file system storage.

`allowedUnits`

The units the format style can use to express the byte count.

`spellsOutZero`

A Boolean value that indicates whether the format style should spell out zero-byte values as text, like `Zero kB`.

`includesActualByteCount`

A Boolean value that indicates whether the format style should include the exact byte count, in addition to expressing it in terms of units. For example, `1 kB (1,024 bytes)`.

`locale`

The locale to use to format the numeric part of the byte count.

## Discussion

In situations that can infer the [`ByteCountFormatStyle`](/documentation/Foundation/ByteCountFormatStyle) type, you can call [`byteCount(style:allowedUnits:spellsOutZero:includesActualByteCount:)`](/documentation/Foundation/FormatStyle/byteCount(style:allowedUnits:spellsOutZero:includesActualByteCount:)-59ep0) instead of explicitly using this initializer. This is the case when you call <doc://com.apple.documentation/documentation/Swift/BinaryInteger/formatted(_:)-4qd73> on a <doc://com.apple.documentation/documentation/Swift/BinaryInteger>.
