Adding a new file to a published content makes it different from translated page of that (SOLVED)

Hi,

I have a content type called "My_Content_Type" which has a file filed called "My_File_Field".

"My_Content_Type" is multilingual (translatable).

I have added a content called "My_Content" having a file, and translated the content (called "My_Content_Trans").

Now, I want to add a new file to "My_Content", it's ok, but it will not be added to "My_Content_Trans" automatically. I should upload the file separately in "My_Content_Trans". This way there will be TWO files on my server:

"My_Content" 's file link to "my_file_uploaded", but
"My_Content_Trans" 's file link to "my_file_uploaded_0"

How can I make for both "My_Content" & "My_Content_Trans" to link to "my_file_uploaded" ?
