How can I open a file with SQL (FW) extension for translating it . (editing)

[Nikita]

I beg your pardon, but I do not know English, so I will use Google translator. I wanted to open FW format firmware, I used this guide https://forums.rockbox.org/index.php?topic=52004.0
. I got the sql file but I didn't really understand what to do next. Could you explain to me very detailed how to get the files? . (Because I'm new to this stuff.) Or take them out and send them to me. The sql format firmware itself https://drive.google.com/file/d/1g1zRoD-mwZfNPnG0W5LBXbTz3tGoiuSk/view?usp=sharing
