I am trying to list files using @uifiledlg but cannot filter the files correctly.

When I use

%file="C:\MyPath\"
!buttonClick=@uifiledlg(%file, "prg", "open")

all .prg files will be listed.

But when I use

%file="C:\MyPath\"
!buttonClick=@uifiledlg(%file, "wf1", "open")

the list contains, not only .wf1 files, but all files in the directory.

Can I restrict the list to contain only .wf1 files?

Best,
Kristian
