MS Windows Thumbnail Cache Format (TDB)

MS Windows thumbnail cache Format is a raster file format which is produced by Microsoft. It is used to store thumbnail images for Microsoft Windows Explorer's thumbnail view.

This speeds up the display of images as the smaller images do not need to be recalculated every time the user views the folder.

LEADTOOLS also supports thumbnail format for Vista beside earlier versions of windows.

This file format does not support progressive loads and saves, multi-page files, stamps, or Lossless JPEG compression, but it does support RGB Sub-formats.

The default extension used by this format is: db.

This file format is supported by the DM Thumbs 2.0.

LEADTOOLS supports version Thumbs.db created for Windows XP and version Thumbcache_xxx.db created for Windows Vista of this file format.
