Non-standard
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 FileSystemDirectoryReader interface of the File and Directory Entries API lets you access the FileEntry-based objects (generally FileSystemFileEntry or FileSystemDirectoryEntry) representing each entry in a directory.
Because this is a non-standard API, whose specification is not currently on a standards track, it's important to keep in mind that not all browsers implement it, and those that do may implement only small portions of it. Check the Browser compatibility section for details.
Methods
readEntries()- Returns a an array containing some number of the directory's entries. Each item in the array is an object based on
FileSystemEntry—typically eitherFileSystemFileEntryorFileSystemDirectoryEntry.
