Though see below for a refinement of this point. Thanks, that's very helpful. I guess you are running Windows in Greek, or at least using the Windows-1253 "code page" which supports both English and Greek characters. The real problem we're working on is not exactly "mixed languages" as such but rather "mixed code pages", that is, file names which include characters that are not represented in the active Windows code page. Examples would be Greek or Cyrillic characters when your code page is set to Western European (CP 1252). I think this is the case for Periklis, who reported the problem. Allin
