## FileFormatInfo::get_LoadFormat method


Gets the detected document format.

```cpp
Aspose::Words::LoadFormat Aspose::Words::FileFormatInfo::get_LoadFormat() const
```

## Remarks


When an OOXML document is encrypted, it is not possible to ascertain whether it is an Excel, Word or PowerPoint document without decrypting it first so for an encrypted OOXML document this property will always return [Docx](../../loadformat/).

## Examples



Shows how to use the [FileFormatUtil](../../fileformatutil/) class to detect the document format and encryption. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>();

// Configure a SaveOptions object to encrypt the document
// with a password when we save it, and then save the document.
auto saveOptions = System::MakeObject<Aspose::Words::Saving::OdtSaveOptions>(SaveFormat::Odt);
saveOptions->set_Password(u"MyPassword");

doc->Save(get_ArtifactsDir() + u"File.DetectDocumentEncryption.odt", saveOptions);

// Verify the file type of our document, and its encryption status.
System::SharedPtr<Aspose::Words::FileFormatInfo> info = FileFormatUtil::DetectFileFormat(get_ArtifactsDir() + u"File.DetectDocumentEncryption.odt");

ASSERT_EQ(u".odt", FileFormatUtil::LoadFormatToExtension(info->get_LoadFormat()));
ASSERT_TRUE(info->get_IsEncrypted());
```


Shows how to use the [FileFormatUtil](../../fileformatutil/) class to detect the document format and presence of digital signatures. 
```cpp
// Use a FileFormatInfo instance to verify that a document is not digitally signed.
System::SharedPtr<Aspose::Words::FileFormatInfo> info = FileFormatUtil::DetectFileFormat(get_MyDir() + u"Document.docx");

ASSERT_EQ(u".docx", FileFormatUtil::LoadFormatToExtension(info->get_LoadFormat()));
ASSERT_FALSE(info->get_HasDigitalSignature());

System::SharedPtr<Aspose::Words::DigitalSignatures::CertificateHolder> certificateHolder = CertificateHolder::Create(get_MyDir() + u"morzal.pfx", u"aw", nullptr);
auto signOptions = System::MakeObject<Aspose::Words::DigitalSignatures::SignOptions>();
signOptions->set_SignTime(System::DateTime::get_Now());
DigitalSignatureUtil::Sign(get_MyDir() + u"Document.docx", get_ArtifactsDir() + u"File.DetectDigitalSignatures.docx", certificateHolder, signOptions);

// Use a new FileFormatInstance to confirm that it is signed.
info = FileFormatUtil::DetectFileFormat(get_ArtifactsDir() + u"File.DetectDigitalSignatures.docx");

ASSERT_TRUE(info->get_HasDigitalSignature());

// We can load and access the signatures of a signed document in a collection like this.
ASSERT_EQ(1, DigitalSignatureUtil::LoadSignatures(get_ArtifactsDir() + u"File.DetectDigitalSignatures.docx")->get_Count());
```


Shows how to use the [FileFormatUtil](../../fileformatutil/) methods to detect the format of a document. 
```cpp
// Load a document from a file that is missing a file extension, and then detect its file format.
{
    System::SharedPtr<System::IO::FileStream> docStream = System::IO::File::OpenRead(get_MyDir() + u"Word document with missing file extension");
    System::SharedPtr<Aspose::Words::FileFormatInfo> info = FileFormatUtil::DetectFileFormat(docStream);
    Aspose::Words::LoadFormat loadFormat = info->get_LoadFormat();

    ASSERT_EQ(LoadFormat::Doc, loadFormat);

    // Below are two methods of converting a LoadFormat to its corresponding SaveFormat.
    // 1 -  Get the file extension string for the LoadFormat, then get the corresponding SaveFormat from that string:
    System::String fileExtension = FileFormatUtil::LoadFormatToExtension(loadFormat);
    Aspose::Words::SaveFormat saveFormat = FileFormatUtil::ExtensionToSaveFormat(fileExtension);

    // 2 -  Convert the LoadFormat directly to its SaveFormat:
    saveFormat = FileFormatUtil::LoadFormatToSaveFormat(loadFormat);

    // Load a document from the stream, and then save it to the automatically detected file extension.
    auto doc = System::MakeObject<Aspose::Words::Document>(docStream);

    ASSERT_EQ(u".doc", FileFormatUtil::SaveFormatToExtension(saveFormat));

    doc->Save(get_ArtifactsDir() + u"File.SaveToDetectedFileFormat" + FileFormatUtil::SaveFormatToExtension(saveFormat));
}
```
