Windows Explorer is able to display files and folders using various methods. One of these methods uses thumbnails. Windows Explorer can extract thumbnails from images, animations, web pages, and some Microsoft Office files. Fortunately the Windows Explorer is able to work with 3rd party plug-ins and display thumbnails for virtually any document type. The extension available on this page allows thumbnail extraction for all document types supported by RW tools, including images, icons, static and animated cursors, and supported 3D formats (U3D, R3I, and 3DS).
Version 3.0 of ReaWolrd Thumbnails is capable of displaying thumbnails created in RealWorld applications up to version 2010.1.
Windows XP, Vista, and Windows 7: RWThumbnails32.msi
Windows x64 editions: RWThumbnails64.msi
You must pick the correct version for your Windows. 64-bit will only work on 64-bit systems and the same is true vor 32-bit systems.
