It happens to me that when I edit mission of an offline campaign to modify something (e.g.: adding FoW) and then save it, I can no more see briefing. I think to have understood an empty ru.properties file is then created and shown in briefing screen. I spent a couple of minutes to copy in a DOS window all *.properties files into *_ru.properties file just by COPY command, but I thought would be nice to have next campaigns (as well as revised ones) already having this implement. This, of course, if I'm not missing something.

For a campaign to work both in modded and unmodded installs it needs both missionname_ru.properties and missionname.properties,
this is because modded games use the russian version of the il2.exe. To solve problems with old campaigns, Total Commander will give you the ability to batch rename files in different folders.

Thank you!

There is also "Bulk Rename Utility", which is a fabulous tool.

Just for background info, SEOW allows you to generate _ru.properties files automatically for each new mission.

Where I can find these tools?
