For example with attached pdlua external (needs pdlua)

You need some kind of external, as it's not possible with pure Pd to
split a symbol at a certain character. You could also use something
like Zexy's symbol2list for this task - use 

 [makefilename %c] 
to generate a backslash symbol to feed into s2l's right inlet then.

Using Lua has the big advantage that you can do some more string
processing in the same object immediatly and in my experience, once
you start with text processing you often need a bit more power anyway,
that's why I'd prefer Lua here.
