FileSystemEntry.fullPath

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

This can also be thought of as a path which is relative to the root directory, with a "/" prepended to it to make it absolute.

Syntax

var fullPath = FileSystemEntry.fullPath;

Value

A USVString indicating the entry's full path.

Example

This example shows a function which is called with a file system; it then gets a FileSystemFileEntry for a file named data.json and returns its full path.

function gotFileSystem(fs) {
  let path = "";

  fs.root.getFile("data.json", { create: true, exclusive: true }, function(entry) {
    path = fullPath;
  }, handleError(error));

  return path;
}

Obviously, this is somewhat contrived, since we know that the file's full path is "/data.json", having just looked it up ourselves, but the concept holds up for scenarios in which you don't know it.
