Vista and quicktime files

I just installed quicktime to view mov files (it seems even using another player you need to install quicktime for the codec (I guess).

Anyway, now as soon as I play or do anything with a mov file, I cannot delete or move any other mov file on my HDD or ext HDD - it says the file is open by another program. But i have nothing running (in the foreground) at least. I tried to looking for a quicktime process in process explorer but there is none.

Is this a bug? Is there a way for me find which process is locking the mov files? It's only the mov files that are an issue - I can delete and move any other type of files.

 

Try opening up msconfig or spybot or winpatrol and looking at the programs running at start-up. To access msconfig go to the start menu, click on run, and type in msconfig, then press enter. Quicktime usually starts at start-up unless you disabled that already. You could also try uninstalling, then reinstalling quicktime. Now the option I would use is find quicktime alternative, install that along with the bundled media player classic, then delete quicktime and never look back.

 

Disable qttask.exe in msconfig.

Don't use QT Alternative, QT lite is better and newer

QT Lite

 

I have done all of the suggested things. Unistalled Quicktime - files are again deletable and accessible.. But once I install Quicktime Alternative I get the same exact problem. A reboot makes the files movable/deletable but once I play one, all are locked.

There is no qttask.exe process or any other qt*.* processes running. I have installed Unlocker, but when I use it it tells me no processes or handles are using the file - but still can't move it or delete it. I have changed ownership to myself (instead of all Admins) - nada.

It's the weirdest thing - and I have googled this but have not found anything comparable.

HELP!!!!!!!
