This question has appeared a few times on the forum, but I'm not sure a definite answer is available...
Sometimes I need to delete/rename/replace an FLV file that is in use by Wowza (because someone is watching it). When I try to do so, Windows obviously tells me that the file is in use by another application (possibly java.exe?).
Is there a procedure/software I can install or run that would allow me to "unlock" the file and perform these operations? Obviously, the end users who are watching that file would receive some sort of error... but that's not a problem. In case of a mistake or an urgent need for a change, having an error message is better than watching a 1-hour video that is altogether wrong.
Windows is very flaky in this regard. I might try Java 7 to see if it is better. I am pretty sure Wowza is not holding on to the file. You may also try a tool such as this to forcefully unlock the file:
