Using DIRECTORY procedure with wildcards

Hi there,

I am using the DIRECTORY procedure with the following arguments:
DIRECTORY( Glo:File_Queue, '*.txt')

Somehow, this procedure returns all files with an extension that
starts with txt (so e.q. also file.txtx).
But, when the path argument contains 'ART.*.txt' it will find only the
files 'ART.*.txt' and not the files with the txtx extension.
Is there any reason for this behaviour, or am I doing something wrong
here?

Thanks for any advice in this!
