No - all local disk write access is not permitted. http://code.google.com/appengine/docs/java/runtime.html The Filesystem
A Java application cannot use any classes used to write to the filesystem, such as java.io.FileWriter. An application can read its own files from the filesystem using classes such as java.io.FileReader. An application can also access its own files as "resources", such as with Class.getResource() or ServletContext.getResource(). Only files that are considered "resource files" are accessible to the application via the filesystem. By default, all files in the WAR are "resource files." You can exclude files from this set using the appengine-web.xml<http://code.google.com/appengine/docs/java/config/appconfig.html> file.
