    Windows Explorer - thumbnails for JPG fail if over 10MB


    Recently windows started having a problem displaying thumbnails for JPGs. If I load a folder of images it shows them all for a moment, then swiftly changes loads of them to white blanks.

    A bit more investigating and I realise it's only for image files over 10MB. I'm a photographer, so looking at images litterally all day, so it's quite an annoyance! Or course I use other software for sorting, organising, resizing etc, but plenty of times you just want to load a folder and see the images.

    Here's a screengrab, sorting a folder by size, anything larger than 10MB is a white blank icon:

    Any ideas?

  2. No thumbnails for images >10Mb in explorer

    Since a few weeks I get no thumbnails in windows 10 explorer for images >10mb.

    Also on desktop.

    Files <10mb generates perfect images.

    It doesn't matter what format it is, tiff, jpg.

    I think there is changed a value in the registry file of windows.

    Who can help me to solve this annoying problem?

    Thanks,

    Theo

    Windows Explorer - thumbnails for JPGs don't show for files over 10MB

    Thanks for getting back to me - virtual memory currently set to auto, and showing as a huge 49,152 (Of a recommended 2,936!) I've tried setting the Virtual memory of C to 10,000 and I'll restart and see if it helps

    What program is the default for opening pictures (what opens when double-click the JPG)?

    I tried clearing the cache. I found a manual method that didn't work, but then a freeware that seemed to clear it ( I saw the desktop icons rebuild.) Still didn't fix it.
    I changed the default JPG program from ACDSee (My choice of image viewer) back to photos, but it didn't fix it either I'm afraid

    Then try this:
    In the search, type "Folder options" and press Enter.
    Go to the "View" tab.
    Check "Always Show icons, never thumbnails".
    Click Apply button.
    Uncheck "Always show icons, never thumbnails".
    Click OK button.
    Search for "adjust the appearance and performance" and click the first result.
    Make sure "Show thumbnails instead of icons" is checked and click OK.

    Thanks so much for the response. I got all excited then... but realised it hadn't fixed it. It's just files over 10MB. I'm trying to think anything I installed recently, so I can uninstall it. Perthaps I'll do a system restore to a point a week or two ago

    Thanks, as always for the help everyone, but I tried clearing the thumbnail cache again, both methods, and the problem is still there I'm afraid.
    I tried system, restore, but it's only showing me entries for the last week. Is there a way of accessing System restore points that may be hidden from the list? I'm sure there were loads of earlier points I've seen in the past

    When the size of the restore points altogether reaches the maximum size allowed, then the oldest ones will be deleted to make space for the new ones to keep within that limit. System Restore doesn't hide system restore points, so unfortunately they're gone if can find them.

    do have the option to reset Windows 10, although that should be done after all of our options have been eliminated because it removes r programs.

    I'm not sure how cleared r icon cache, but if didn't already do this, try it:


    • Press Ctrl+Shift+Esc to open Task Manager.
    • Go to Details tab.
    • Kill explorer.exe. Taskbar will disappear. (the time, icons, etc.) Before doing this, make sure aren't copying any files or anything.
    • File > New Task in Task Manager, type cmd.exe and click OK (check the run with admin box).
    • Type cd %LOCALAPPDATA%\Microsoft\Windows\Explorer into Command Prompt and press Enter.
    • Type del /f /q *.db and press Enter.
    • Type explorer.exe into Command Prompt and press Enter. Taskbar will reappear.
    • are free to close those windows.

    And if that doesn't work, try setting the built-in photos app as the default photo viewer instead of ACDSee. The program associated with the file can affect the thumbnail it displays. To do that, search for "default apps", and scroll down until see the default photo viewer option. Choose Photos as the default and check to see if the icons begin displaying properly.

    Thanks You. It said access denied to every .db file it found for some reason, even though explorer was closed
