Detecting contenttype of .msg files

[David]

Hi,

We are using RadAsyncUpload and saving the ContentType property of the uploaded file.

For most uploaded files, .pdf, .docx etc. the ContentType property has been detected.

When uploading an .msg file the ContentType property is null.

Is this an known issue? Do you have any suggestions?

Thanks.

Hello,

The reason for this behavior is because this file format is not part of the MIME type list. The file format needs to be part of that list in order the ContentType to be set properly. You can replicate same issue with the <input type="file" name="file upload">.

This is not correct - up until very recently we were able to upload .msg files just fine so either somebody took .msg away as a valid MIME type or something changed with the RadAsyncUpload control because the MVC version of the control works just fine.

I tried different ways, not all in the code snippet:
Java 7 Files.probeContentType(path)
URLConnection mime detection from file name and content type guessing
JDK 6 JAF API javax.activation.MimetypesFileTypeMap
MimeUtil with all available subclass of MimeDetector I found
Apache Tika
Apache POI scratchpad
