File extension .CKT

B2 Spice Circuit Design Format | Altium | Data Files |
The CKT file extension is associated with CircuitMaker. This application is used for designing, creating and simulating electronic circuit schematics developed by Altium. CKT refers to CircuitMaker schematic documents, and is used for created projects. These files are basically text documents containing the source code for a schematic project. Such documents may be edited and used in more advanced CircuitMaker tools. Projects can then be published to access others to collaborate or provide feedback on the design.
Additional Information
The CKT format was introduced with CircuitMaker v6, and was the result of changing from a binary file format. Previous versions of the software used the .SCH file format, which was replaced by the plaintext-based .CKT. It is important to note that the two formats are not compatible. .CKT files are sometimes referred to as structure-transparent files and allow circuit designs to be modified externally, apart from CircuitMaker. Similar formats include: .MDB, MFH, and .MAV, all related to Altium's products.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .CKT) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .CKT extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .CKT file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .CKT extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .CKT extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .CKT file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .CKT file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .CKT file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .CKT file) will be extended to the maximum.
It is also good to check
- if the .CKT file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
