I recently noticed that I am seeing .dat files in the storage folders where previously I only had the .bvr video files.

The first .dat files were created on 05/05/2025, which might coincide with an update I did on Blue Iris. I did not make any changes to the camera configuration at that time.
I've seen mention of .dat files being related to AI/Codeproject, but I do not use any of those features. When trying to open the .dat file in Blue Iris, it stats that the file is corrupt.

Here is an example showing the video files and

Does anyone know why these are being created and how I could disable them or have them located elsewhere if they are necessary?

A new feature since 5.9.9.44. Leave them alone.

[5.9.9.44] Database metadata is now stored alongside BVR files in separate .DAT files. If the database is ever lost or alerts are deleted, they may be restored from these files.
