MapInfo workspace
File type: GIS, GPS navigation and map file
A wor file extension identifies a MapInfo workspace. A wor file stores the arrangement and settings of a MapInfo project.
The workspace refers to map layers, tables, windows, queries, and other items used in the project.

The wor file extension is associated with MapInfo mapping and geographic analysis software for Microsoft Windows, developed by Pitney Bowes Software Inc.
A wor file is a workspace file, commonly containing instructions and settings for opening tables and map layers, arranging map and browser windows, applying styles, and restoring a project layout. It normally refers to the associated MapInfo data files rather than storing all of the geographic data itself.
The format is used with MapInfo on Microsoft Windows. Because it describes a workspace and its references, it is not normally a standalone GIS data format and may depend on the referenced files remaining available.
On Microsoft Windows, open the wor file with MapInfo or MapInfo Pro. The workspace's referenced tables and other data files should be available in their expected locations; otherwise, MapInfo may report missing data or open only part of the workspace.
TatukGIS Editor and Total GIS Converter are also associated with this file type on Windows, although support for particular workspace contents may vary.
A wor file is a workspace description, not a container for all of the geographic data, so it generally cannot be converted as a single dataset. Open it in MapInfo or use compatible tools to export the referenced tables or layers individually to the required GIS format.
Exporting the data does not necessarily preserve the original workspace layout, window arrangement, queries, or styling. Keep the source data files with the workspace if the project itself must remain usable.
