What is an XCI file?

XCI files mostly belong to Vivado by Xilinx. An XCI file is a video game extracted from the storage card of a Nintendo Switch console. It contains a backup or patch for a game. Such XCI files are encrypted to prevent tampering. However, Switch console emulators can read them. Another type of XCI file contains the IP configuration of a project created with Vivado hardware design, analysis, and synthesis environment. Acrobat document authoring and viewing software uses an XCI file to save its font mapping settings. XCI is also the filename extension of the main file in a game project created with XCI (eXtremely Compact Interpreter).

How to open an XCI file

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

If the file extension or signature does not match the file format, errors will occur when opening or editing the file. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the XCI files is as follows:
