Maybe not the perfect topic, but I didn't want to open a new for this, sorry...

Well, the basic conception is - if I'm not wrong - that the Match parts of the filetypes are stored globally in the recognition.db as part of the system, and the Action parts are stored in different files, which can the users edit for their needs.

The thing which joins the two files is the mime type, isn't?

Well, if I create e.g. a JPEG file into the sys:prefs/ambient/filetypes/image/jpeg with the content:

AMTD
1
Name JPEG Image file
Type image/jpeg
Action
...
End
...
End

The filetype at next boot is recognized as "Datatype". What's wrong? Is it an Ambient bug, or am I stupid? :)
