Does the Aspose API can get the file properties without open the file?

Hi, Support:

I want to know whether the Aspose APIs could read/Write the file properties such as title, keywords,pagecount,WordsCount and so on without open the file?
Though the APIs can read/Write those file properties, it rather take long time to open and then close the file, whereas the DSO.dll can read/Write those file properties fastly.

Can you please share the requirements that which document types you are referring to so that we may check the availability of requested support in concerned API.
