[GNC] General Ledger

[Adrien Monteleone]

I hadn’t noticed since most of my files have extensions anyway, but indeed, I just tested a markdown file by removing the extension. It changed the association from Atom to TextEdit, but couldn’t open it. (Something about UTF-8 not being applicable. ?? Really ?? Opening with Atom worked fine though.)

Preview doesn’t work either as noted.

Thanks for the info.

Regards,
Adrien

The pre-NeXTStep MacOS used a extended attribute to determine file type and the early versions of Mac OS X continued the practice. Support for that was deprecated in 10.6 and while not formally removed it seemed to stop working in 10.7. There is limited support for determining file type from the command line by looking at the file header, but Finder can't do that. File type displayed in Finder, application associations, and QuickLook  display of files is all driven by the extension.
