Fun with files named test

Praxis

This is just a heads-up in case you encounter this behaviour and wonder if you are going mad...

Copy these attached files to a directory (or create your own equivalents):
  test_obj.txt   Rename it to test.obj (cannot attach .obj files here) - it just defines 2 Vertices and a Line between them
  test.duf        A Cube primitive
  test.dsa        A 1-line script that shows a message

Run DAZ Studio, and:
    Import test.obj - Actually, test.dsa is excuted.
  Rename test.dsa to test1.dsa (or anything different)
    Import test.obj - Actually, test.duf is loaded.
  Rename test.duf to test1.duf (or anything different)
    Import test.obj - At last - test.obj is imported.

This happens only with files named test - any other names work normally.

DAZ Studio v4.10.0.123 and v4.11.0.236 both behave this way.
