The COTX file extension is associated with some products by Corel and used for texture files.
COTX files provide texture resources for use in Corel graphics projects and effects. They are intended to be used by the compatible Corel product rather than as general-purpose image files.
Open a COTX file with the compatible Corel graphics product that uses it. It may need to be loaded through the product's texture or resource controls rather than opened as a standalone image.
Use a COTX file in compatible Corel software. Any export options depend on the Corel product that supports the file.
