File Formats: 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 supports the thumbnail format for all versions of Windows including XP.

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 Thumbs.db created for Windows XP and Thumbcache_xxx.db created for Windows Vista and later.
