FLfile object

FLfile.getAttributes()

Availability

Flash MX 2004 7.2.

Usage

FLfile.getAttributes(fileOrFolderURI)

Parameters

fileOrFolderURI A string, expressed as a file:/// URI, specifying the file or folder whose attributes you want to

retrieve.

Returns

A string that represents the attributes of the specified file or folder.

Results are unpredictable if the file or folder doesn’t exist. You should use FLfile.exists() before using this method.

Description

Method; returns a string representing the attributes of the specified file or folder, or an empty string if the file has no

specific attributes (that it, it is not read-only, not hidden, and so on). You should always use

FLfile.exists() to test

for the existence of a file or folder before using this method.

Characters in the string represent the attributes as follows:

• R — fileOrFolderURI is read-only

• D — fileOrFolderURI is a folder (directory)

• H — fileOrFolderURI is hidden (Windows only)

• S — fileOrFolderURI is a system file or folder (Windows only)

• A — fileOrFolderURI is ready for archiving (Windows only)

For example, if fileOrFolderURI is a hidden folder, the string returned is "DH".

Example

The following example gets the attributes of the file mydata.txt and displays an alert box if the file is read-only.

var URI = "file:///c|/temp/mydata.txt";

if (FLfile.exists(URI)){

var attr = FLfile.getAttributes(URI);

if (attr && (attr.indexOf("R") != -1)) { // Returned string contains R.

alert(URI + " is read only!");

}
