What Civinator is talking about has nothing to do with your .biq file names, it has to do with where they're being stored.That might be too technical for me.
All my .biq files have different names: 126, 127, 127A, 127B, etc.
Civ3 and its Editor pre-date WinVista, like other programs of that era, by default installs into the C:/ProgramFiles(x86)/ directory, where your essential operating system files are (also) installed. Unfortunately for Civ3 players, modern Windows versions (Vista and above), are specifically designed to protect that location from potential malware damage, by preventing all unauthorised (non-Admin) programs -- such as the Civ3 Editor -- from writing files into it.
This means that if you've installed Civ3 in its default location, any changes to .biq files made by the Editor are not actually stored in the 'official' Civ3 directory (i.e., where the game 'expects' them to be), they're quietly shoved into the 'VirtualStore', a harmless mirror-location elsewhere on your HDD (or SSD, these days!). Windows knows where the 'mirror' files are, so e.g. you can open them from your desktop, or in the Editor, but the game itself only looks at the 'real' installation location, and your edited files won't be there.
