The tp_catalog file extension is associated with ThumbsPlus, an image-organizing and searching application for Microsoft Windows developed by Cerious Software.
A tp_catalog file contains a catalog scheme used by ThumbsPlus. It is application data that defines or stores information for the way a ThumbsPlus catalog is organized, rather than an image file.
The file belongs to the ThumbsPlus catalog system and is intended to be used by the application together with its other catalog data. It is not designed as a general-purpose interchange format.
Open a tp_catalog file with ThumbsPlus on Microsoft Windows. Install a compatible version of ThumbsPlus, then use the application's catalog or catalog-scheme functions to load the file.
A tp_catalog file may not provide useful results when opened directly outside ThumbsPlus, because it contains application-specific catalog data.
A tp_catalog file is a ThumbsPlus catalog scheme rather than a document or media format, so it cannot usually be converted meaningfully with a general-purpose converter.
To use the information in another ThumbsPlus catalog, load or recreate the scheme in ThumbsPlus. Keep the original file when transferring or backing up the associated catalog.
