    W8 keeps deleting thumbnail cache (changed folder permission)


    Hi.

    Normally in windows 7 I would change the folder persmission to deny "detele files and folders", but these options are greyed out on my windows 8. I'm the admin, and even if I log in as super administrator it's still greyed out.

    How can I fix this problem and prevent W8 from deleting thumbnail cache?

    I too are having this problem. How can I stop the thumbnails from deleting all the time?

    Hello.
    I have the same problem regarding thumbnails in windows 8.
    You can change the permissions to a folder following the tutorial posted here: Prevent Windows 8 File Explorer From Deleting Image Thumbnail Cache.
    But, anyway, this doesn't solve the problem for me. Win 8 is randomly recreating the cache every 10 to 48 hours. I don't know why this is happening and i couldn't find a fix.

    Looks like they broke it trying to fix something else. I have so far given up looking for a solution.

    Has anyone found a working fix for this? I have seen a lot of comments that the permissions fix does not work. Have not seen anything that people are consistently saying fixes this problem.

    ....... changing the permissions didn't work for me either

    As far as I understand from the tutorials on changing the file permissions is the thumbnail database limited to a certain size.

    Is it possible to change the size value for the thumbnail cache somewhere - If yes, where and how ?

    It seems that quiet a lot of Windows 8 users having the same thumbnail cache issue and I hope someone is coming up with a solution soon .......

    Solution Found !


    ....... in my case I found a solution and hope it will work for others as well.
    I experimented a little with the permissions after I did what is subscribed here:

    Prevent Windows 8 File Explorer From Deleting Image Thumbnail Cache

    I addition to that I deleted the original SYSTEM permissions and changed the new created SYSTEM permissions from "Deny" to "Allow" and configured it like shown in the image below and did the same for my user account permissions.

    Click image for larger version

    That was it and now the thumbnail cache won't rebuild itself over and over again.
    If someone is eager to try it out please leave a comment if it worked or not .......

    Fixed, or not


    After applying the fix as tommygun said thumbnails aren't deleted anymore but i keep getting explorer.exe crashes:
    Faulting application name: Explorer.EXE, version: 6.2.9200.16433, time stamp: 0x50763312
    Faulting module name: thumbcache.dll, version: 6.2.9200.16384, time stamp: 0x501080ee
    Exception code: 0xc0000005

    So i restored permissions to default value.

    We need a proper solution for this. Doesn't Microsoft know about this yet? I wonder if we are doing something wrong here. Something like this shouldn't too hard to catch because everybody seems to be having this.
