About a month ago I acquired a large .mkv file. Cutting to the chase, I deduced that when, in explorer, I simply clicked on the folder containing this file, my available memory started to disappear about 10-20MB a second until it was depleted; at which point system performance came to a near halt. I also eventually found out that it was the process explorer.exe that held all of this available memory, EVEN THOUGH the task manager AND resource manager showed that explorer held a steady... 25MB. On my 4GB ram system, after just about a minute, all 2.5 gigs were gone and when the explorer.exe process was ended, all that mystery memory re-appeared.
Booting in Safe Mode, clicking on this folder did not produce the same result.
Over the next few weeks, I acquired more and more .mkv's. NOT ALL OF THEM create this problem, but about 40% of them do, with the exact same symptoms.
I tried disabling thumbnail previewing on individual files AND folder thumbnailing, and it STILL caused this super annoying issue.
I can not move these large .MKVs to another hard drive unless I am in safe mode. not acceptable.
