Are you sure that the 540k file is for the logbook?
Check all the subfolders in wgs.
For me, it had 6000 flights and the last one was on 4 April 2025. After I deleted my logbook file in wgs, a new one started, with no flight in FS2024 logbook.
For me I have 15 flights since clearing the file and it now stands at 13.5mbso the size of my file is mainly driven by my profile associations I believe (the more I add the bigger the file gets).
It has occurred to me that the file I think is “the logbook file” is actually not and is my “control profile” file. I have no other file that is anywhere even approaching 1mb. It may be that ANY file that exceeds 16mb throws a 2047.
Since switching to Spad, I can tell you the size/growth of the logbook/whatever file doesn’t have any connection to control profiles. It seems to grow at several mb per flight for me, and at maybe half that speed with dev mode on when it shouldn’t be logging at all
Same thing happening to me on Xbox X idk is there any way to fix this? Read posts saying even when you clear everything it comes back. And no word from devs….. everything else is great but with this error popping up can’t fly anymore…
