how to set dynamic file name connection ssis

HI ,

i am loading the data from excel as source to sql server table as destination.the problem here is i stored the one excel file name in one folder and in the package excel connection i am browsing into that folder.

after once the above load is done i am moving that file from one folder to other folder.

and after some time i have stored different excel file name in same folder ,i wanted to set it as when ever the excel file name changed the package needs to fetch dynamically and run.

could anyone help me here.

Thanks,
