Password protected docm- dotm recognized as docx

Hi,

I use this code to determine file type:

FileFormatInfo info = FileFormatUtil.DetectFileFormat(MyDir + "Document.doc");
Console.WriteLine("The document format is: " + FileFormatUtil.LoadFormatToExtension(info.LoadFormat));
Console.WriteLine("Document is encrypted: " + info.IsEncrypted);

But when I tried to detect file type for password protected docm and dotm - I received following:
The document format is: .docx
Document is encrypted: True

Is it correct behavior?
docm and dotm without password protection are identified fine.

Thank you,
Alex Shloma

Hi Alex,

Thanks for your inquiry. The FileFormatUtil.DetectFileFormat detects and returns the information about a format of a document stored in a disk file.

Even if this method detects the document format, it does not guarantee that the specified document is valid. This method only detects the document format by reading data that is sufficient for detection. To fully verify that a document is valid you need to load the document into a Document object.

Hope this answers your query. Please let us know if you have any more queries.

Hi Tahir,

I do not need to check if document is valid (“it does not guarantee that the specified document is valid”). I just need to detect document format.
“This method only detects the document format by reading data that is sufficient for detection. To fully verify that a document is valid you need to load the document into a Document object.” - I have issue that both (FileFormatUtil.DetectFileFormat and doc.OriginalLoadFormat) returns .docx for password protected docm, dotm, dotx. For all others cases all works as expected. When document in OpenXML format is password protected - Aspose always says that this is docx format.

Thank you,

Hi Alex,

Thanks for your feedback. Please note that FileFormatUtil.DetectFileFormat detects and returns the information about a format of a document stored in a disk file.

If you use the following code, the FileFormatInfo.LoadFormat return Docx because the document is encrypted. For an encrypted OOXML document, it is not possible to ascertained whether it is an Docm, Docx, Dotm.

FileFormatInfo info = FileFormatUtil.DetectFileFormat(MyDir + "passProtected.docm");
Console.WriteLine(info.LoadFormat); // info.LoadFormat return Docx because the document is encrypted.

So, in this case, the Document.OriginalLoadFormat Property will return correct file format.

LoadOptions loadoption = new LoadOptions();
loadoption.Password = "test";
Document doc = new Document(MyDir + "passProtected.docm", loadoption);
Console.WriteLine(doc.OriginalLoadFormat.ToString()); // This will return docm.
