Copying and moving folders are similar tasks in nature and come in synchronous and asynchronous forms. Both require that you create two File objects, the first being the source directory and the second being the destination directory. Listings 8.1 through 8.4 demonstrate how to copy and move directories using the synchronous and asynchronous methods provided in the File class. You may notice that folders containing many files and folders take longer to copy and move than empty folders. When you need to move larger folders, it is useful to use the asynchronous methods instead of the synchronous methods so that your application can perform other tasks while waiting for the operating system to move or copy your folders.

Note that the copyTo and copyToAsynchronous methods include Boolean optional second parameters that indicate whether or not these methods should overwrite existing directories. By default, this parameter is false and an IO Error event is used to indicate that the destination folder already exists. If this parameter is set to true, the destination folder is overwritten with the source folder.

Deleting folders
Connect ucc-128 with .net

To delete a directory, you can use the synchronous deleteDirectory()or asynchronous deleteDirectoryAsync() method provided in the File class. Just as moving and copying large folders can take a noticeable amount of time, the same is true for deleting a directory; it is good to use the asynchronous method when deleting directories since your application will seem frozen while the operating system deletes a directory. Both deleteDirectory() and deleteDirectoryAsync() accept the deleteDirectory Contents parameter. The deleteDirectoryContents parameter is a Boolean parameter that indicates whether the non-empty folders should be deleted along with their contents. The default value of this parameter is false. Unless it is set to true, the folder being deleted would need to be empty in order to delete it. Listings 8.5 and 8.6 demonstrate how to delete a folder that has content in the synchronous and asynchronous forms.

Using the Filesystem
You can also move folders to the trash instead of deleting them entirely by using the moveToTrash() and moveToTrashAsync() methods. You can use these methods in the same manner as you use the deleteDirectory() and deleteDirectoryAsync() methods.
Using Files
Interacting with files is similar to working with folders. The only difference is that when working with files, you have the added ability to manipulate the data in a file by reading, writing, and appending. Most of the methods, such as copyTo and moveTo, that are available for folders are also available for use on files. Moving and copying files is identical to moving and copying folders, only the File object needs to be pointed to a file instead of pointed to a folder. Deleting a folder is nearly identical to deleting a folder, only you use deleteFile() and deleteFileAsync() instead of deleteFolder() and deleteFolderAsync().
Copying a file
Copying files are similar to copying folders, as discussed in the section on using and copying folders. A small difference between copying and moving folders and files is that when creating the source and destination File objects, a file is referenced instead of a directory. You use the same methods of a File object copyTo(), copyToAsync(), moveTo(), moveToAsync() to copy and move files. The following example shows how to copy a file:
var source:File = File.desktopDirectory.resolvePath( source. txt ); var destination:File = File.resolvePath( destination.txt ); source.copyTo(destination, true);
Notice that the second parameter of copyTo is set to true to indicate that the destination file should be overwritten if it exists already.
