All of these files appear in the file browser in sublime except the file ‘nrpe.cfg.prod.db’. This file is also not searched when performing a global search - this is how I discovered it was missing, I made changes in all the places sublime search found a string but it missed this file.

Is there some list of filename extensions or otherwise which are excluded from being shown in a directory?

This is not part of a project - just a directory I opened in sublime to edit the files.

Preferences > Settings - Default.

Make all changes in Settings - User so it’s not overridden.

As C0D312 was likely planning to mention, you want to be looking at the file_exclude_patterns setting in those files
