Chapter 18: FLfile object
Availability
Flash MX 2004 7.2.
Description
The FLfile object lets you write Flash extensions that can access, modify, and remove files and folders on the local file
system. The FLfile API is provided in the form of an extension to the JavaScript API. This extension is called a shared
library and is located in the following folder:
• Windows Vista:
boot drive\Users\username\Local Settings\Application Data\Adobe\Flash CS3\language\Configuration\External
Libraries\FLfile.dll
• Windows XP:
boot drive\Documents and Settings\username\Local Settings\Application Data\Adobe\Flash
CS3\language\Configuration\External Libraries\FLfile.dll
• Mac OS X:
Macintosh HD/Users/username/Library/Application Support/Adobe/Flash CS3/language/Configuration/External
Libraries/FLfile.dll
Note: Don't confuse the shared libraries that contain symbols in your Flash documents with the JavaScript API shared
libraries. They are two different things.
The FLfile methods work with files or folders (directories) on disk. Therefore, each method takes one or more
parameters to specify the location of a file or folder. The location of the file or folder is expressed as a string in a form
very similar to a website URL. It is called a file URI (Uniform Resource Identifier) and is formatted as shown here
(including the quote marks):
"file:///drive|/folder 1/folder 2/.../filename"
For example, if you want to create a folder on the C drive called config and place it in the Program Files/MyApp folder,
use the following command:
FLfile.createFolder("file:///C|/Program Files/MyApp/config");
If you then want to place a file called config.ini in that folder, use the following command:
FLfile.write("file:///C|/Program Files/MyApp/config/config.ini", "");
To create a folder on the Macintosh, you could use the following command:
FLfile.createFolder("file:///Macintosh/MyApp/config");
