Sub CompareDocument(Doc: IDocument);
Var
    FName: String;
    FInfo: IFileInfo;
Begin
    FName := Doc.FileName;
    If File.Exists(FName) Then
        FInfo := New FileInfo.Attach(FName);
        //If the file on the disk differs from that saved in the document, then
        //load a new version to the document
        If (Doc.CreationDate <> FInfo.CreationTime) Or
            (Doc.ModificDate <> FInfo.LastWriteTime) Or
            (Doc.Size <> FInfo.Size) Then
            Doc := (Doc As IMetabaseObject).Edit As IDocument;
            Doc.LoadFromFile(FName);
            (Doc As IMetabaseObject).Save;
        End If
    Else
        //If the file does not exist, unload it from the document
        Doc.SaveToFile(FName);
    End If;
End Sub CompareDocument;
