How to Find Out If a PowerPoint Presentation File Is Corrupted or Not in Java?

We are using Aspose.Slides Java v24.7 to convert ppt document into text, but when user passes any corrupted file then we are getting Out of memory error from Aspose library. I used below code to check file is corrupted or not, and it takes almost 4GB Heap memory for 10 MB corrupted file (attached for reference), to check file is corrupted or not.

InputStream inputStream = new FileInputStream("/File124.ppt");
IPresentationInfo info = PresentationFactory.getInstance().getPresentationInfo(inputStream);
if (info.getLoadFormat() == 255) {
    System.out.println("File is corrupted!");
}

So, Can you please suggest a better way to check if a file is corrupted or not?
