I believe it is a 6 digit number.
123456.spx (voice)
123456.rec (screen)
On the recording server they can be found at C:\Program Files\Common\QM\Recordings
On a users machine, they can be found at C:\Program Files\Common\SQM\Recordings
They appear to increment in chronological order, however on the server, they are stored in different folders. So 123456 could be in folder A, while 123457 could be in folder B. Not sure the reason for that, but hope this is what you are looking for. If not, you might want to go to Calabrio's website directly, as they are the maker of the AQM product.
