What is a CP1 file?

CP1 files mostly belong to Freestyler DMX. CP1 files serve two main roles. They are used primarily to store lighting control data for Eurolite fixtures. In this case, the files contain fixture settings and DMX control instructions that work with software like Freestyler DMX.

Lighting Control Data: These files hold configuration and control data to drive stage and event lighting. For more details, see the manufacturer page.

They are also used as backup files for Mitsubishi PLC units. In that role, CP1 files store program and configuration data, and are managed with tools such as Mitsubishi FR Configurator2. Some instances of these files are referred to as Omron PLC program files.
FilExt.com tip: This dual usage means that the origin of a CP1 file should be confirmed before choosing the appropriate software to open and view it.

How do you open CP1 files?

You need a suitable software like Freestyler DMX to open a CP1 file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your CP1 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a CP1 file directly in the browser:. Just drag the file onto this browser window and drop it.

CP1 file format:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. Knowledge is power - this also applies when dealing with unknown or faulty files.

The CP1 file extension is not found very often and mainly uses a defined CP1 format. The two most popular formats are as follows:

The file size is in the range of 550 bytes to 1 KB. The file type is relatively new. Such CP1 files store data about eurolite, channel, spot, mode, moving, head, beam, light and wash.
• 15% of all CP1 files start with the magic bytes 01 00 2E 43 50 31, which are always the first bytes of this file format. They consist of unreadable binary data. CP1 files can be up to 28 KB in size, but are often around 26 KB - 28 KB. The keywords FR INV COPY FILE and FR-A800 are typical for these files. An example of a file name is CP001.CP1.
