auto rename

Dear Helpers,
i created a rename rule file*.jpg should be called only file.jpg.
If I move a file file1q2412.jpg from a local folder to the server folder Test, it will be automatically renamed to file.jpg.
On the otherhand, if my ipcam sends to file2015.jpg to the server folder Test, it does not rename it. 
What do I have to change that it works?
Thanks for the help
