# Interface FileSystemDirectoryEntry

The **`FileSystemDirectoryEntry`** interface of the File and Directory Entries API represents a directory in a file system. It provides methods which make it possible to access and manipulate the files in a directory, as well as to access the entries within the directory.

[MDN Reference](https://developer.mozilla.org/docs/Web/API/FileSystemDirectoryEntry)

interface FileSystemDirectoryEntry {  
    [filesystem](#filesystem): [FileSystem](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.FileSystem/);  
    [fullPath](#fullpath): string;  
    [isDirectory](#isdirectory): boolean;  
    [isFile](#isfile): boolean;  
    [name](#name): string;  
    [createReader](#createreader-1)(): [FileSystemDirectoryReader](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.FileSystemDirectoryReader/);

## Properties[](#properties-1)

### `Readonly`filesystem[](#filesystem)

filesystem: [FileSystem](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.FileSystem/)

The read-only **`filesystem`** property of the FileSystemEntry interface contains a FileSystem object that represents the file system on which the entry resides.

[MDN Reference](https://developer.mozilla.org/docs/Web/API/FileSystemEntry/filesystem)

Inherited from [FileSystemEntry](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.FileSystemEntry/).[filesystem](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.FileSystemEntry/#filesystem)

### `Readonly`fullPath[](#fullpath)

fullPath: string

The read-only **`fullPath`** property of the FileSystemEntry interface returns a string specifying the full, absolute path from the file system's root to the file represented by the entry.

[MDN Reference](https://developer.mozilla.org/docs/Web/API/FileSystemEntry/fullPath)

Inherited from [FileSystemEntry](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.FileSystemEntry/).[fullPath](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.FileSystemEntry/#fullpath)

### `Readonly`isDirectory[](#isdirectory)

isDirectory: boolean

The read-only **`isDirectory`** property of the FileSystemEntry interface is true if the entry represents a directory (meaning it's a FileSystemDirectoryEntry) and false if it's not.

[MDN Reference](https://developer.mozilla.org/docs/Web/API/FileSystemEntry/isDirectory)

Inherited from [FileSystemEntry](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.FileSystemEntry/).[isDirectory](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.FileSystemEntry/#isdirectory)

### `Readonly`isFile[](#isfile)

isFile: boolean

The read-only **`isFile`** property of the FileSystemEntry interface is true if the entry represents a file (meaning it's a FileSystemFileEntry) and false if it's not.

[MDN Reference](https://developer.mozilla.org/docs/Web/API/FileSystemEntry/isFile)

Inherited from [FileSystemEntry](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.FileSystemEntry/).[isFile](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.FileSystemEntry/#isfile)

### `Readonly`name[](#name)

name: string

The read-only **`name`** property of the FileSystemEntry interface returns a string specifying the entry's name; this is the entry within its parent directory (the last component of the path as indicated by the fullPath property).

[MDN Reference](https://developer.mozilla.org/docs/Web/API/FileSystemEntry/name)

Inherited from [FileSystemEntry](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.FileSystemEntry/).[name](https://docs.maptiler.com/sdk-js/api-reference/interfaces/Externals.FileSystemEntry/#name)
