Open CPT File

The files that have the CPT extension have various format options, some of them we will see below:

Corel PHOTO-PAINT

In this case, a CPT file is a bitmap image created by Corel PHOTO-PAINT.

It is a photo editing program that is part of the CorelDRAW Graphics Suite.

Corel PHOTO-PAINT is offered mainly for Windows and Mac based Operating Systems, although at one time it was also sold for Linux. Additionally, it is the main competitor of Adobe Photoshop.

The CPT file contains an image that supports layers, alpha channels, transparency, and other image effects.

CPT files are used by amateur and professional photographers and graphic designers to store modified or enhanced photos.

One thing to keep in mind is that the CPT file is basically a container for images and their subsequent modifications and edits.

Export a CPT file

Lastly, the CPT file format is not supported by many image editors, however, you can export the file in PHOTO-PAINT to more widely supported image formats such as JPG , PNG , GIF and BMP.

ccrypt

In this application, CPT file is a file encrypted with ccrypt, which is a utility for encrypting and decrypting files and streams.

A brief description of ccrypt

ccrypt, written in lowercase, is a utility for secure encryption and decryption of files and network transmissions.

It was designed as a replacement for the standard UNIX encryption utility, crypt, which is known to use a very weak encryption algorithm.

CPT for ccrypt

In this use case, the CPT file is based on the Rijndael cipher and uses an asymmetric encryption algorithm, which will obviously require a password to open it.

Compact Pro

Here the CPT extension file is a file compressed with Compact Pro, an old file compression program for Mac OS Classic and earlier.

For this use, the CPT uses a fast and efficient compression algorithm.

Development of Compact Pro stopped in the late 1990s, and the program is no longer supported.

DTS-Compact

In the latter application, the CPT file is an audio file used by DVD authoring programs.

DTS-HD Master Audio Suite

A prime example is the Master Audio Suite from DTS, which includes a multichannel lossless audio codec developed by DTS as an extension to the DTS Coherent Acoustics lossy codec.

CPT for DTS Compact

Here, the CPT contains audio, timecode, and header data, and is used together with the video data to create DVDs.

It is important to note that CPT files cannot be used to create Blu-ray discs, however the DTSHD format can be used.
