Hi Zhiju,

+  #Search File by extension name
+  def SearchbyExt(self, Ext):
+    FileList = []
+    for path in self.InfPath:
+      for root, _, files in os.walk(path, topdown=True, followlinks=False):
+        for filename in files:
+          if filename.endswith(Ext):
+            FileList.append(os.path.join(root, filename))
+    return FileList

I think this function can support to search by multiple file extensions, that would be more efficient. 

Thanks,
Bob
