.CXI File Extension
What is a CXI file?
A CXI file is an executable file used to play a Nintendo 3DS game in a 3DS emulator. It contains a disk image that is a copy of a Nintendo 3DS game. CXI files are similar to, though not the same as, .3DS files.
Gamers who want to play Nintendo 3DS games on their computer or other non-3DS devices use emulators to simulate the 3DS on those devices. Before they can load games into an emulator, players must either create emulator-compatible game files themselves, by "dumping" data from their game cartridges into packaged game files, or download pre-packaged game files from the Internet. Game files packaged for 3DS emulators can be saved using a number of file formats and extensions, including .3ds, .CIA, and .cxi.
Notably, the programs Braindump and GodMode9 allow 3DS players to create CXI files from games installed on their Nintendo 3DS. Players then use these files to play 3DS games using the Citra Nintendo 3DS emulator.
NOTE: While either 3DS or CXI files can be used to play games in Citra, the files' contents are not the same. Most importantly, some 3DS files may contain multiple CXI files, only one of which is used to install and play a game. The others contain non-essential game data, such as the game's manual and updates.
How to open a CXI file
To play the Nintendo 3DS game contained within a CXI file, first download and open Citra. Then, from the emulator's menu bar, select File → Load File. Navigate to and select your CXI file; the game it contains will open in Citra.

What is a CXI file?
Image created by FMAT 8100 HTS System, an instrument used to study human cells; contains RAW image data of scanned specific wells or a whole plate of beads.
CXI images can be viewed in three different ways:
- Grayscale - Shows relative intensities
- Histogram - Shows three-dimensional height display that show relative intensities
- Two Color - Shows the Dye A and B events with selected colors but does not display relative intensities
Once created, CXI image files are placed in the "Images" folder. Each images subfolder contains a CXI image file for each scanned well. The CXI image file will be named according to the location of the scanned well. For example, Img02x0C.cxi indicates that the image data was taken from a well in column 2 and row C.
A CXI image can be exported to the JPEG format through the FMAT program. Select File → Export Image, choose the folder you'd like to place the file from the "Look in" drop down menu, name the file, and click Save.
