Explorer thumbnails (winXP)

I have a file format I need to be able to show in explorer thumbnails. Since the target system is windows XP, the Vista PreviewHandler API will not be suitable. Ill be using c++.

How would I do it?

Solution

  • You'll need to register a shell extension for your file type. The extension contains code that extracts/generates the thumbnail by implementing the IExtractImage interface.

    See: IExtractImage Interface on MSDN
