I was very annoyed that Quick Look would activate when I didn't want it to, instead of dragging files. The settings shown in my screen shots allow me to now use one finger to drag a file instead of it opening with Quick Look. Hope this helps someone!
So you confirm that the issue is with the trackpad on a macbook, right?
I am pretty sure my initial "diagnostic" is correct.
Try going to System Preferences->Trackpad and under "Point and Click" turn OFF Force Click and Haptic Feedback.
Then I am sure that you will not be able to cause Quicklook to activate while you want to drag.

You are probably clicking too hard and activating force touch.
That is quite common especially if you are usedto an older mac that doesn’t have force touch.
I don't have an older Mac with a touchpad. I have a mouse for my iMac, and then my iPad an iPhone. I use the touchpad gently. Changing the settings helped, and I can now drag with one finger instead of have quick look open.
I have an iPhone that is less than 6 months old and an iPad less than 2 years old with sensitive touch screens. I don't have a touchpad on my iMac. This is my first MacBook, and I'm light on the touch with the keys and the touch pad. If anything, I press too softly at times.
Thank you for the additional info and devices you own. The Force Touch and sometimes the two- finger touch on Trackpad can activate unintended results such as what you have experienced. Just take trial and error and eventually the computer teaches us how it wants us to function ( humour here ;-)) )
Have a Great Day, Afternoon or Evening
How old was your previous Apple Computer ? That was what the previous posting was about.
