Some callers (i.e. ISOProperties) don't want the full path, so giving them it is unnecessary. Those that do want it can use GetPathFromFSTOffset. Not storing full paths everywhere also saves a small bit of RAM and is necessary for a later commit. The code isn't especially pretty right now (callers need to use FST offsets...) but it'll become better later.
