The FileSystemEntry
interface's method copyTo
()
copies the file specified by the entry to a new location on the file system. There are some typical restrictions on what you can do:
- A directory can't be copied into itself.
- An entry can't be copied into its parent directory unless you specify a new name.
- When copying a directory, the copy is always recursive; you can't leave out subfolders.
Syntax
FileSystemEntry.copyTo(newParent[, newName][, successCallback][, errorCallback]);
Parameters
newParent
- A
FileSystemDirectoryEntry
object specifying the destination directory for the copy operation. newName
Optional- If this parameter is provided, the copy is given this string as its new file or directory name.
successCallback
Optional- A function which is called when the copy operation is succesfully completed. Receives a single input parameter: a
FileSystemEntry
based object providing the copied item's new details. errorCallback
Optional- An optional callback which is executed if an error occurs while copying the items. There's a single parameter: a
FileError
describing what went wrong.
Return value
Errors
FileError.INVALID_MODIFICATION_ERR
- The requested operation involves an impossible change, such as moving a directory inside itself or one of its own child directories, or copying an item within the same directory without renaming it.
FileError.QUOTA_EXCEEDED_ERR
- The operation exceeded the user's storage quota, or there isn't enough storage space left to complete the operation.
Example
This example shows how a temporary log file might be moved into a more permanent "log" directory.
workingDirectory.getFile("tmp/log.txt", {}, function(fileEntry) { workingDirectory.getDirectory("log", {}, function(dirEntry) { fileEntry.copyTo(dirEntry); }, handleError); }, handleError);
