What is a CXI file?

CXI files mostly belong to HDFView.

Scientific Data: CXI files often use the HDF5 format to store X-ray imaging data. This format supports a hierarchical structure that can hold large datasets with metadata. You can open these files with specialized tools such as HDFView.

Game File: In some cases, CXI files serve as 3DS game save files (for example, used in titles like Tomodachi Life). For these, the Citra Emulator is a common tool to view or modify the saved data.

Flowchart File: Another variant of the CXI format is based on XML. These files are used by flowchart design programs (sometimes noted as a CX Designer Flowchart File) and work with applications like Flowgorithm. More details are available on the Flowgorithm website.

FilExt.com note: To decide which tool to use, inspect the file's internal structure (for instance, look for XML tags or HDF5 markers). This helps determine whether it holds scientific data, game save information, or flowchart designs.

How to open a CXI file

You need a suitable software like HDFView to open a CXI 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 CXI file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a CXI file directly in the browser:. Just drag the file onto this browser window and drop it.

Xitech COMPAxiON is a 32-bit software (Windows 9x, Windows ME, Windows NT 4.0, Windows 2000 & Windows XP) solution that enables data to be stored in files in a compressed form, therefore making the files many times smaller than would normally be required. Unlike other compression programs, COMPAxiON has the ability to randomly access the data stored in these files. Often used with files like Foxpro database files to reduce their size on disk.
