Yes. Safari writes to disk in a location managed by the system, which is automatically purged at Apple-specified intervals. This has caused me problems a time or two, since it occasionally deletes a file I have open in Skim, and that file is gone for good if I quit and relaunch Skim. > Or are such 'temporary files' ever created in RAM only? Technically it could be created from PDF data in RAM only, but that would be pointless. Suppose you want to view a 100 MB PDF file; keeping that in RAM is going to needlessly inflate your heap usage, and likely the OS would swap it out to disk anyway. It's only potentially worthwhile for tiny files, and you can't even a priori guarantee the size of a download. ------------------------------------------------------------------------------ Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!
