This method finds out if an input PDF file is a PDF Portfolio. Each PDF Portfolio file may contain several files of various types (textual documents, presentations, drawings, etc.).

## Syntax

### C++

```cpp theme={null}
HRESULT IsPdfPortfolio(
  BSTR                    FileName,
  IImagePasswordCallback* Callback,
  VARIANT_BOOL*           Result
);
```

### C\#

```csharp theme={null}
bool IsPdfPortfolio(
  string                 FileName,
  IImagePasswordCallback Callback
);
```

### Visual Basic .NET

```vb theme={null}
Function IsPdfPortfolio( _
  FileName As String, _
  [Callback As IImagePasswordCallback = Nothing] _
) As Boolean
```

## Parameters

FileName

Callback

\[in] This variable refers to the interface of the user-implemented object of the type [ImagePasswordCallback](/fine-reader/engine/api-reference/image-related-objects/iimagepasswordcallback) which is used to handle possible password requests for accessing PDF files. This parameter is optional and may be 0 in which case password-protected files cannot be checked.

Result

\[out, retval] This parameter returns TRUE if a PDF file is a PDF Portfolio and FALSE if it is not.
