Map don't open

[Krynia]

Hi everyone.I tried to change background image as in this guide https://scsmoddingguide.github.io/mappi ... mport.html. But after I create scs file and try to open it, in "open file" window I dont have this map (i save map before, and I dont delete it from mod folder, but my map just disappeared).What can i do about it.

I watch this video, and in this moment, I don't have my map
