pub.file:bytesToFile

fileName	String The absolute path name of the file to which to write the byte array.
bytes	Byte[] The byte array to write to the file specified in the filename parameter.
append	String Optional. Specifies whether to append or overwrite if the specified file already exists. The default behavior is to create a new file if file does not exist or overwrite an existing file if file already exists. Set to: true to append to the file if the file already exists. false to overwrite the file if the file already exists.

For security reasons, the pub.file:bytesToFile service checks the input fileName parameter against the list of allowedWritePaths values specified in the fileAcceessControl.cnf file. If the input fileName is not on the allowed list, Integration Server throws an exception. For information about configuring the fileAcceessControl.cnf file, refer to File Access Control Configuration for the pub.file Services.
