■ Root objects cannot be renamed or deleted.

For example, if a path using the slash (/) is used to create a File object, the application

folder is mapped.

■ Applications can be granted access to additional directories by specifying virtual directory

mappings for File object paths.

This is done by specifying a

FileObject tag within the JSEngine section in the

Application.xml file, as shown in the following example:

<VirtualDirectory>/videos;C:\myvideos</VirtualDirectory>

<VirtualDirectory>/fcsapps;C:\Program Files\fcs\applications</

VirtualDirectory>

</FileObject>

</JSEngine>

This example specifies two additional directory mappings in addition to the default

application directory. Any path specified with /videos/xyz/vacation.flv maps to c:/

myvideos/xyz/vaction.flv. Similarly, /fcapps/conference maps to c:/Program Files/fcs/

applications/conference. Any path that does not match this mapping resolves to the

default application folder. For example, if c:/myapps/filetest is the application directory,

then /streams/hello.flv maps to c:/myapps/filetest/streams/hello.flv.

The File object invokes the

Application.onStatus event handler to report errors when the

following File class methods fail:

■ File.copyTo()

■ File.flush()

■ File.list()

■ File.mkdir()

■ File.open()

■ File.read()

■ getGlobal()

■ File.remove()

■ File.renameTo()

■ File.write()
