This is maybe not the best place to ask this question, but I wonder if anyone else has run into this:
I have some big video files, stored on an NTFS partition (from Windows). The partition is mounted in Linux using ntfs-3g. This works well, but for some reason when I open the folder where the files are located in Dolphin, and right click the file in order to do something with it, it immediately starts hammering the disk and usually the system will effectively freeze. I can't even get to a console via ctrl-alt-F1 to kill whatever it is that's freaking out.
I copied the file to my OS drive (ext3) and it works fine there, so it would seem to be rooted in ntfs-3g... combined with the way Dolphin looks at the file when right-clicking it.
If this isn't a known issue maybe I'll try to find someone in the ntfs-3g camp that I can ask.
