    Hello, for about one week now, I have a very strange „problem“ on my computer (Win7 Ulti, 2x i5 haswell). Everything works as fast as can be expected, except for one thing, Windows Explorer. And only with one folder. That folder contains about 30GB of Movies, whereas a folder containing 30GB of audio opens immediately.
    I ran several anti.virus without result, Avast is installed, and I checked malwarebytes and Stinger.
    I use Nividia GeForce GT 630, which has a lot of software installed, seems to me. I do not have or play complicated games.

    Does somebody have an idea what is going on?

    The folder opens as soon as I click on it, but shows nothing inside, it takes at least 5 sec for the content to turn up.
    Of course those 5sec are not the problem, but this never happened before…

    Thanks..

    Video content is heavier than audio content megabytes wise.
    Have you tried defragmenting your hard-drive?
    I also recommend you place your videos in an external hard drive and keep it away from your main pc as a precaution.

    These are just guesswork advice.

    You could try chkdsk:

    chkdsk /f C: (where "C:" is the drive letter)

    Find the view options for that specific folder and turn on "always show icons, never thumbnails"

    Your delay is caused by Windows opening every file in background, to generate a thumbnail image for it.
     
    Stop hovering to collapse... Click to collapse... Hover to expand... Click to expand...

    This. Checking what codecs you have and if they have an issue would be a good starting point.

    If Possible Copy Whole Folder to Other Drive and Then Check.

    As one member mentioned chkdsk /f C: could be bad sector on hard drive hopefully not as for thumbnails loading yes that can cause a delay but if they are already cached then it should not take long only updating new ones forget codecs out of the question unless you are trying to play the movies.

    Thánks anyway. The point is, that the olderopened up instantly until a short while ago... and if Carlos meant Thumbnails for those movies, then of course that function is switched off...
    I have my movies stored away from the pc on an external drive, in that folder are legally recorded and stored TV programs, which I have not had the time to watch yet....

    I use cleaner daily and defrag regularly...

    No there really was sudden change, as if there were one file in there that had a virus or God knows what....:(

    Thanks, the delay was just a few seconds and it was not the problem. I just noticed that something had changed. Turning off thumbnails has changed the opening time to "immediatly"
