{{APIRef("File and Directory Entries API")}}{{Non-standard_Header}}{{Deprecated_Header}}
In the File and Directory Entries API, a FileSystemSync object represents a file system. It has two properties.
[!WARNING] This interface is deprecated and is no more on the standard track. Do not use it anymore. Use the File System API instead.
The FileSystemSync object is your gateway to the entire API and you will use it a lot. So once you have a reference, cache the object in a global variable or class property.
