Try this:

import urlparse, sys
fileURLname = ("file:///C:/Documents%20and%20Settings/Username/"
    "My%20Documents/45-61-Abc%20fold-%20den.vru")
pathname = urlparse.urlparse(fileURLname)[2]
if sys.platform == "win32":
    import nturl2path
    clean = nturl2path.url2pathname(pathname)
else:
    import urllib
    clean = urllib.unquote(pathname)
print clean

It works for me: No trailing characters at all, printable or otherwise. 

>>> len(fileName.split('.vru', 1)[1])
0
