    Windows 8 Pro 64-bit (Boot Camp)

    View Thumbnails in Explorer


    Hi,
    I recently upgraded to Windows 8 on my Boot Camp partition (i'm aware that Apple hasn't officially released drivers for 8 yet, i'm still running the Windows 7 Boot Camp drivers and so far it seems stable).

    I've ran into a little problem in the Explorer. As i'm using an SSD, i have my Windows partition fairly small (~50GB) so i keep all of my photos on my Mac partition and don't duplicate them over.
    When trying to browse through these photos on the Windows side, i can see the file name and the icon, and they open perfectly in Windows Picture Viewer, but within Explorer they all show the same default Windows "Mountain by the lake" icon.

    I've been into Folder Preferences and told it only to display thumbnails and not the icon but still no luck...
    Does anyone have any other ideas?

    Thanks for your help

    I am going to say that because the pics actually reside on OSX, windows is unable to create a thumnail cache. It does this to speed up the viewing time, however your windows really doesn't "own" the pics folder on OSX and may not be able to build this cache properly and therefore you would not have any thumnails. here is an excert from the mighty Wikipedia about it:

    "Beginning with Windows Vista, thumbnail previews are stored in a centralized location on the system. This provides the system with access to images independent of their location, and addresses issues with the locality of Thumbs.db files. The cache is stored at %userprofile%\AppData\Local\Microsoft\Windows\Explorer as a number of files with the label thumbcache_xxx.db (numbered by size); as well as an index used to find thumbnails in each sized database.
    However, when browsing network shares with write permission, Windows Vista and Windows 7 store a Thumbs.db file in the remote directory instead of using the (local) central thumbnail cache. This can cause issues when deleting remote shares, as the directory will become locked for a period of time when selected as Windows Explorer automatically creates a remote Thumbs.db file.
    Creating Thumbs.db files on remote shares can be disabled with a Group Policy setting"

    Hope that makes some sense, it would seem that is the problem to me any way.

    Geeve

    Edit: you could just grab a couple of pics and move them over to the windows side and see if it gives you your preview, that would at least test the cache theory anyway.

    I just tried that and it seems as though you're right. I moved a handful of pictures to the desktop and immediately the thumbnails showed up on both the desktop and when i viewed desktop in explorer.
    So is the problem to do with Windows being able to read but not write onto the OSX drive?

    Thanks

    That would be my guess. I am not a Mac guy, but the file structure would be different and windows would not have permission to or the structure to write the cache file it needs.

    Geeve

    Edit: My understanding is Boot camp is like a Virtual machine and by default the guest OS cannot modify the Host OS in anyway (other than sharing files)
