Find the mime type of a file

[S60_dev]

Hi,

I want to know which is the class used to know the mimetype of a file in S60. Like in UIQ it is "CQikMediaFileFolderUtils"

Similarly how can we find the mimetype of a file in S60. Is there anyway to find other than writing recognizers.

Please let me know on this if anybody know anything.

In S60 use the PathInfo API, same as
In UIQ CQikMediaFileFolderUtils API (GetDefaultFolderPathL)

have a look into RApaLsSession, with it you can recognize any file that has recognizer in the system, AFAIK, you do need a recognizer to recognize a file, since things usually do not just happen without somebody actually doing the required tasks.

Hi,

As you mentioned recognizers, I understand that you are working on the 2nd Edition. A team mate wrote a recognizer to find out the file extension and hence the MIME type but to tell you recognizers don't work in S60 3rd.

We also tried to use the "file header" to recognize the MIME type but nothing really worked. You can search for similar APIs.

That is a personal experince of your team mate. Recognizers obviously work, otherwise you could not open anything with the File Manager.
You can get a working one from SymTorrent, http://symtorrent.aut.bme.hu
But it is true that recognizers need ProtServ capability and protected UID, so they will not work with self-signing for example.

Hi,

Thnx for the reply.
I've written this code snippet. But still unable to get the files count having mimetype.

TBuf8<32> mimetype(_L8("image"));
TBuf<128> filePath;
filePath.Append(_L("c:\\Data\\Images\\"));
TRequestStatus status;
CDataRecognitionResultArray result;
RApaLsSession aApaSession;

User::LeaveIfError( aApaSession.Connect() );
CleanupClosePushL( aApaSession );
aApaSession.RecognizeFilesL(filePath, mimetype, result, status);
TInt Count = result.Count();
aApaSession.Close();
CleanupStack::PopAndDestroy(); // apaSession


Am I doing something wrong here?

Have you taken the wizard's comments into account...

you could try this out: http://wiki.forum.nokia.com/index.ph...ing_file_types

anyway using RApaLsSession for recognizing files, would not require the capability mentioned, only constructing a recognizer dll would require the capability.

Don't you think you should probably include the name of the file as well? Something like "C:\\Data\\images\\image.jpg"
