Subject FDR file in Firebird folder
Author Mark Rotteveel
I just came across this question on Stackoverflow:

The question is: "what is this file .fdr in the directory Firebird . For
me, it weighs 16 gb. Is this a transaction log ? Or how to reduce it ?"

I've never heard of such a file, does anyone have an idea what it could be?
