I have only Finale 2K3 and the demo of 2K5, and both use only 15 temp files in any one session, and never more than that. I've tried opening a lot of files and editing, but it never changes from the default 15. This is something we already knew, as we were told a long time ago that when you open a file, its data is spread across multiple temp files, and each temp file has data from multiple Finale files in it. It was never clear why Coda chose this method, but one thing it would accomplish would be to make copying data between files very fast (since in the temp file, the corresponding data structures would be in the same file, and copying from one to another would be a matter of changing pointers, rather than writing data to different files). That same structure was also suspected of leading to the old file overwrite bug. My understanding is that Finale 2006 has a different temp file architecture entirely, so the specifics of my observations in this thread about temp files do not necessarily apply directly to 2006. But the basic idea is going to be the same, that management of temp files is probably something that's managed through a single set of subroutines that are very easy for a programmer to manage. That is, a change in the temp file architecture should be something that is a black box to the rest of the application. That doesn't mean things can't go wrong, but it limits the places where the code can be bollixed up to one sub-module of the bigger project. > But what I observed was what appeared to be a random interspersing of > dates, where the first x files were from the older date, and that the > more recent files were scattered among higher file names. Well, there are two problems discussed in this thread, one of which we all agree on, and the other of which I don't think actually happens the way you allege: 1. Finale doesn't always delete its temp files when it exits. 2. Finale sometimes re-uses the file data left over in temp files from previous sessions. It's #1 that is not in dispute. Where there *has* been difference on that subject is over whether it's a serious or a minor problem. For me (who was yesterday informed that he's a lightweight user of Finale), I've never had any serious problems that were solved by cleaning up leftover temp files. Secondly, we should distinguish between temp files left undeleted after an orderly Finale shutdown and temp files orphaned when Finale crashes and exits unexpectedly. One can hardly expect Finale to be able to clean up after itself when it crashes, though one might expect Finale to clean up orphaned files the next time it starts (especially given that the temp files have nothing to do with the AutoSave, so, unlike, say, MS Word, aren't of any use in recovering data after a crash). Finale crashes fairly often in comparison to most of the other applications I use, so it's not at all uncommon for there to be temp files orphaned by crashes. But the second allegation I find very, very unlikely, and it would be difficult to prove that it's the case. That is, how, exactly, could you know that Finale is re-using a file's actual *data* and not just deleting it and creating a new file with the same name, or zeroing out the data in the existing file and starting over with all fresh data? It would first of all be extremely unlikely for Finale's programmers to make this kind of mistake (it's a completely obvious issue to avoid in any temporary data scenario -- you've got to check for pre-existing data before initializing your temporary data structures). I can't even think of a way to test this, except to make copies of the orphaned temp files before you launch Finale and then checking to see if the dates of any of them get updated to the current date, and then force quitting Finale (to leave the orphaned files), then doing a byte-by-byte comparison of the copy of the file before Finale opened to the current version of it. But first off we don't even know how much overlap there is between Finale's temp files when they are being created and deleted in an orderly fashion. -- David W.
