Prerequisites

Before we begin, make sure you have the following:

Make sure to replace "Your Document Directory" with the actual path.

Step 3: Get Presentation Information

Create an IPresentationInfo object to get information about the presentation file:

IPresentationInfo info = PresentationFactory.getInstance().getPresentationInfo(dataDir + "HelloWorld.pptx");

Step 4: Check the Format

Use a switch statement to check the format of the presentation:

switch (info.getLoadFormat())
{
    case LoadFormat.Pptx:
    {
        System.out.println("The presentation is in PPTX format.");
        break;
    }
    case LoadFormat.Unknown:
    {
        System.out.println("The format of the presentation is unknown.");
        break;
    }
}

This code snippet will help you determine the format of your presentation file.
