FileSystemDirectoryEntry

TheFileSystemDirectoryEntry interface of theFile 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.

Basic concepts

You can create a new directory by callinggetDirectory(). If you want to create subdirectories, create each child directory in sequence. If you try creating a directory using a full path that includes parent directories that do not exist yet, an error is returned. So create the hierarchy by recursively adding a new path after creating the parent directory.

Example

In the following code snippet, we create a directory called "Documents."

// Taking care of the browser-specific prefixes.window.requestFileSystem =  window.requestFileSystem || window.webkitRequestFileSystem;window.directoryEntry = window.directoryEntry || window.webkitDirectoryEntry;// …function onFs(fs) {  fs.root.getDirectory(    "Documents",    { create: true },    (directoryEntry) => {      // directoryEntry.isFile === false      // directoryEntry.isDirectory === true      // directoryEntry.name === 'Documents'      // directoryEntry.fullPath === '/Documents'    },    onError,  );}// Opening a file system with temporary storagewindow.requestFileSystem(TEMPORARY, 1024 * 1024 /* 1MB */, onFs, onError);
