Work with only one slide

[AdamShakhabov]

My business logical often has the next case:
There is a list of large (big file length, many slides or both) presentations:
presentation1.pptx
presentation2.pptx
presentationN.pptx
In foreach statement this list I need to do stuff with only someone slide. For example, for presentation1 it is might be slide number 4, for presentation3 it is might be 1.

PROBLEM
Spire.Presentation opens large presentation a long of a time, even if I need work with only one slide from it.

QUESTION
There is any way to optimize the opening presentation to work with a certain slide?

Dear Adam,

Thank you for your inquiry.
There's no way to just load one slide because it is unreasonable. Just imagine, without loading the whole document, the application would not know the total slides number or the structure, then it's impossible to locate a certain slide according to the index.
For big files, absolutely it would cost a long time. Anyway, could you please share your large files to help our dev team investigate if there's an approach to optimize the time?
Please upload the files to DropBox or OneDrive and then provide the download link.

Sincerely,
Jane
