Launching Quicktime always opens multiple files

After upgrading to Lion, Quicktime always re-opens all of the movies I've opened in previous sessions.

That is what it is supposed to do if you leave player windows open when quitting the QT Player app. Remember, one of the new features of Lion is the "remembering" of every open window in an application, their locations, etc. so that when an appication is re-opened, it opens with exactly the status as when last closed so you can continue what you were doing at the time you closed the application.

Is there some way to prevent this stupid prctise? I often open several files, then quit the app rather than closing each individual file. This is counter-productive.

There may or may not be. If there is, I have yet to find it. (I'm still in the "familiarization" stage.) If there isn't, it would make a good enhancement request, especially if it could be turned off/on by application.

I tend to close players after use, so this doesn't really bother me. (On the other hand, I make a lot "what if" saves and am not really fornd of the idea of a new "auto-save" feature confusing me between my project saves and its saves.)

Oh, well... To each his (or her) own.

My hat is off to you! Thanks for posting the solution.

thanx appreciated.

If you generally like Resume in other apps, but don't want it in QuickTime or other single apps, you can disable them individually via the terminal:

defaults write com.apple.QuickTimePlayerX NSQuitAlwaysKeepsWindows -bool false

Another solution that I found to work - bind the keys so that when you quit with Cmd-Q it'll do what you want. In System Preferences, go to Keyboard, then Keyboard Shortcuts. On the left side, choose Application Shortcuts. Below the right side listing of the listing, click the plus of the +- widget, and start making a new keybinding for Quicktime Player.app.

The name of the first one to add is "Quit and Close All Windows". Get it exact, this one will be bound to Cmd-Q, of course. Since those keys are already taken, though, this won't quite work yet. Add another key binding for "Quit QuickTime Player", and put it on Cmd-Option-Q. Set like this, you can leave QT open across a system restart, but clean up everything by manually Quitting.

NO NO NO APPLE stop it!!!

This is just the sort of nonsense PC used to play and now Apple is infected!

I just recently ran into this problem. I'm running El Capitan on my Macbook Pro. What I ended up having to do is to go to applications in finder then hold down shift while launching the QuickTime application. When I did that it seemed to clear out the files that opened every time I was opening the application before. To test it out, I quit the QuickTime application then opened it again normally, and it opened QuickTime without any issues of multiple files opening.

Hopes this helps out anyone running El Capitan this present day.

I just found the answer to this irritating problem and as usual it is very simple, I take no credit but am happy to share it. In el Capitan go to system preferences>general and check the box "Close windows when quitting an app" it works immediately.

Tried this, didn't work for me
