A '.' is legal in a Zope ID, but is not legal in a python id. This means 
that in expressions, you can't easily refer to your object.

So <dtml-var file.exe> works, but <dtml-var "file.exe"> referes to the 
attribute or method named 'exe' on the object 'file'. You'll have to refer 
to the object with a namespace lookup: <dtml-var "_['file.exe']">
