This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The read-only name property of the FileSystemEntry interface returns a USVString 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).

A USVString indicating the entry's name.


This example shows a function called isFileWithExtension() which returns true if the specified FileSystemEntry is both a file and the file's name ends with a given extension.

function isFileWithExtension(entry, extension) {
  return (entry.isFile && entry.name.endsWith("." + extension));
