I moved tridionThumbnailCache folder and multimedia image into D drive and updated <Tridion.ThumbnailDirectory>D:\Tridion\tridionThumbnailCache</Tridion.ThumbnailDirectory> in System.config.

Now I am facing issue multimedia component image not displaying in CME due to folder permission issue.

Looking solutions for tridionThumbnailCache permission updates.

  • Have you set that the same user have same permissions over new folder just as over old one? Feb 9 '17 at 8:01
  • I moved old folder into another d drive. Feb 9 '17 at 17:07

    If you move a Folder with inherited permissions, you can effectively change its ACL. Try using ProcMon to see why the file access fails. Feb 10 '17 at 9:06
  • @RickPannekoek yes i agree, also my point. Folder can change its inheritance if moved. Also, you should check which user should have write permissions over tridionThumbnailCache folder. I guess that it should be MTSUser. Feb 10 '17 at 9:22
  • I guess it should be NT AUTHORITY\NETWORK SERVICE. Feb 10 '17 at 10:21

actually, they do. I worked this out with SDL support recently. you keep the thumbnail cache setting there. But that's a virtual path under IIS. What you do in IIS is set new virtual directory to your custom location.

You can do that in PowerShell like this:

Import-Module WebAdministration
New-WebVirtualDirectory -Site "SDL Web" -Name "ThumbnailCache" –Application "WebUI" -PhysicalPath "D:\Tridion\tridionThumbnailCache"

SDLWeb not support to custimize the Thumbnail cache directory due to permission issue. I revert my custimized change and using default directory and permissions.

    <!-- Thumbnail cache directory -->
