bonjour,

je viens de jeter un oeil chez canon. A priori, en décompressant l'archive, tu devrais avoir un fichier ".FIR" (firmware) et un fichier ".pdf" (doc d'installation du firmware)

Q&A Section:
Preparations for the Firmware Update:

Windows
After the downloaded compressed file (.zip) is extracted, a firmware folder is created.

*Extracting the downloaded file: Right-click the zip file, and then select Extract All to extract the file. The extracted folder contains the firmware (file name: 7D000203.FIR / file size: 17,461,788 bytes) and instructions on the firmware update procedures (a PDF file in five languages: Japanese, English, French, Spanish, and Simplified Chinese).

Before starting the firmware update operations, please confirm the contents of the download, and carefully read through the firmware update procedures.
