Ehe...looks like various windows programs have issues to open it...funnily enough notepad opens it....hmmm...interesting case.
edit: ok...simply putting quotes around it or using a short name conversion doesn't help to open the file. Unfortunalety "DragQueryFile" which is used e.g. when drag'n dropping a file returns the pipe symbol...wonder what else can be used to open it.
Anyway....guess it's a pretty weird filename and I wonder how it was created anyway.....maybe some unicode weirdness....nothing really to care about, isn't it
