The Entry interface of the FileSystem API represents entries in a file system. The entries can be a file or a DirectoryEntry.

 
 public interface Entry {


  
The file system on which the entry resides.
 
 
   String getFullPath();


  
The entry is a directory.
 
   boolean isDirectory();


  
The entry is a file.
 
   boolean isFile();


  
The name of the entry, excluding the path leading to it.
 
   String getName();


  

Copy an entry to a different location on the file system. You cannot copy an entry inside itself if it is a directory nor can you copy it into its parent if a name different from its current one isn't provided. Directory copies are always recursive—that is, they copy all contents of the directory.

void vopyTo (
(in DirectoryEntry parent, optional DOMString newName, optional EntryCallback successCallback, optional ErrorCallback errorCallback);
);
Parameter
parent
The directory to which to move the entry.
newName
The new name of the entry. Defaults to the entry's current name if unspecified.
successCallback
A callback that is called with the entry for the new object.
errorCallback
A callback that is called when errors happen.
Returns
void
 
   void copyTo(DirectoryEntry parent);

Move an entry to a different location on the file system. You cannot do the following:

  • move a directory inside itself or to any child at any depth;
  • move an entry into its parent if a name different from its current one isn't provided;
  • move a file to a path occupied by a directory;
  • move a directory to a path occupied by a file;
  • move any element to a path occupied by a directory which is not empty.

Moving a file over an existing file replaces that existing file. A move of a directory on top of an existing empty directory replaces that directory.
