It looks like UploadHelper in C# doesn't allow for setting the mimetype.  You can skip UploadHelper and do it like this:     EsuRestApi cloudRest = new EsuRestApi("cloudonestorage.peer1.com", 443, uid, sharedSecret);  Acl acl = new Acl();  acl.AddGrant(new Grant(new Grantee(cloudRest.GetUid(), Grantee.GRANTEE_TYPE.USER), Permission.FULL_CONTROL));             long totalBytes = new FileInfo(fromfile).Length;  Stream s = File.OpenRead(fromfile);  cloudRest.CreateObjectFromStreamOnPath(new ObjectPath(tofile), acl, null, s, totalBytes, "application/pdf", null);  s.Close();    Also note that the ACL you're creating is the default; you could just use 'null' in the ACL argument if that's the ACL you want.  I'll also open a ticket to allow setting the mimetype in the C# UploadHelper.
Hi,  When I try to open a file from Atmos using Shareable URL in Google Chrome, it is not opening. However it opens well with IE 8 and Mozilla.  Please help.  Thanks and regards,  Ratish.
