Have you encountered a problem with a CPT file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a CPT file here. In the further part of this page we have added a list of programs that should open your CPT file. It is enough you choose a proper application for your operating system, download and install it.


CPT files are image files in the native format of Corel Photo-Paint. Photo-Paint is the image editor of the CorelDraw Graphics Suite and is not available separately. Similar to Adobe Photoshop, Photo-Paint offers many features for professional image editing and is used quite often in prepress.

CPT files are image files that can contain masks, layers, shapes and lenses in addition to the actual image information. Grayscale, CMYK and LAB color space are supported.

The CPT format is proprietary and as of version 7 can only be read or converted by Corel products. In addition, the format is not 100% backwards compatible and even newer versions of Photo-Paint (X-Series) can not read pictures from older versions 6 and below. Note that Corel PaintShop Pro can not handle CPT files.

How to open a CPT file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the CPT file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a CPT file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support CPT files. At this point we are looking for disk space where the application was installed in and we can link it with a CPT file. Since then, our operating system will use the selected program to support all CPT files.

Other issues

Despite the described problem with CPT there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the CPT file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the CPT file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
