“这个是我常用的资料夹” equals “This is my frequently used folders” or "This is my favorite folder"?
I would translate &quot;This is my frequently used folders.&quot;to &quot;这个是我常用的资料夹。&quot;
Because &quot;frequently used&quot; exactly means &quot;常用的&quot;, while &quot;favorite&quot; is more like &quot;最喜欢的&quot;。
