FileSystemDirectoryEntry

Instance properties

This interface has no properties of its own, but inherits properties from its parent interface, FileSystemEntry.

Instance methods

This interface inherits methods from its parent interface, FileSystemEntry.

createReader(): Creates a FileSystemDirectoryReader object which can be used to read the entries in this directory.
getDirectory(): Returns a FileSystemDirectoryEntry object representing a directory located at a given path, relative to the directory on which the method is called.
getFile(): Returns a FileSystemFileEntry object representing a file located within the directory's hierarchy, given a path relative to the directory on which the method is called.
removeRecursively(): Removes the directory as well as all of its content, hierarchically iterating over its entire subtree of descendant files and directories.

You can create a new directory by calling getDirectory(). 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.

Examples

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

js

// 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 storage
window.requestFileSystem(TEMPORARY, 1024 * 1024 /* 1MB */, onFs, onError);
