A couple thoughts: Can you try to figure out exactly when it happens? If you have maybe 20-50GB *usable* free space (i.e. 30-75GB actually free), get a whole bunch of really large files together and go through them in turn, and then restart QS or the whole computer and do it in a different order—try to really nail down exactly when it happens. I had written a whole bunch more here, but the more I think about it from what you said, the answer is likely to be…:
..."always" (i.e. any file with no extension gets loaded into memory, which is a problem for big ones. btw try it with "small" files, like 100MB—make sure you have free RAM, open up Activity Monitor and watch QS' memory usage when browsing to such a file—should jump by exactly the size of the file if I'm right). And aHA, in that case it still might have something to do with QuickLook, sort of, although it'd be a kind of weird bug. You said a 1.6GB movie with its extension removed caused the same issue, only you have enough RAM that it topped out before you killed it? Now try that same movie *with* the extension—works, right? (Fancy preview and everything.) If so, QS must be *somehow* deciding that when it sees a file with no associated QuickLook plugin/extension (not sure which), it's going to load the whole thing into memory for some reason. (Actually, try renaming your movie file to something.thisisamovie, i.e. a bogus extension, and see if it does it then—that'd nail down whether it's based on QuickLook/LaunchServices/etc bindings, or on the extension itself). *Why*, and therefore where in the code the bug is, I have no idea. If the answer *isn't* "always", well, then it depends on what the answer is :). ---- Second thought: I can tell you that this is almost undoubtedly a B69+Snow Leopard bug. It doesn't happen with B69/Mountain Lion. Actually, thought—try running B69 in 32-bit mode: http://imgur.com/9XgYf. This is shotgun debugging, here, but if it has something to do with (a) a 32-bit kernel + 64-bit QS (shouldn't be, but never say never), or just a Snow Leopard bug that somehow interacts…well, shotgun debugging, as I say. Knowing more about when this happens, if the answer isn't "always", would be a big help here. For our sake it'd be nice if you went through with all this, so the bug can get fixed for other SL users—but from your post above I can tell that you have almost definitely 8GB+ of RAM, so once we figure the bug out you could also just upgrade to Mountain Lion and be done with it (I wouldn't go near Lion let alone ML on a machine with 4GB, my previous machine had 3 and that was barely enough for SL). Also, if the bug still appears, that would tell us yet something else. I just recently said "okay this is dumb I'm tired of waiting" and went through with the upgrade and haven't had any problems yet, despite a good deal of mucking with the system in the past. Developers in general have been really good about updates, I haven't even had to set Gatekeeper to "All applications" yet. ---- Oh, last thought: the first thing I should have said is, "reset" QS (http://qsapp.com/wiki/FAQ#How_to_Quickly_Reset_Quicksilver_Settings) and see. If it's a plugin, go through them half at a time—which one it is will tell us a ton. Check if it happens for all files first, but then at least check *if* resetting fixes it, even if you don't want to go through the bisect process with a ton of plugins.
