I have a 2.9GB MKV file, unzipped from a .RAR archive, that causes explorer.exe to take up 100% CPU when I select it by single clicking. Also, when I attempt to copy and paste it, the copy dialog hangs on the "Discovering files" phase until I end the process. It is also the only video file in the folder that lacks a thumbnail image from the video; it is simply a VLC icon. However, it plays normally in the player.
I suspect somehow the file info got corrupted and Windows keeps trying to read it, but I don't know how or why, or how to fix it. I downloaded it again from the source and extracted it again, didn't fix it. After moving via cut and paste (which took unusually long), the problem persists. I would think the size would not be an issue, as it is neither the largest nor the smallest file in the directory.
Any help would be appreciated.
