What do you want the director to get out of your QLab file?
I don't personally find it very inconvenient to download QLab, but if you are sharing your file with them off of a thumb drive, you can just stick QLab on the drive and run it off of there to open it. It's just under 34mb.
Sharing the QLab bundle with your director will let them see all the audio and video files.
But if your director wants to see the cue list the same way you see it in QLab, then the QLab app is a pretty good way to do that.
You can also select all your QLab cues, copy, and then past onto a spreadsheet. But if you have some longer note cues, then those can behave a little oddly in formatting there.
But QLab doesn't have any export options to a spreadsheet or anything like that.
