for each loop files in folder against file log table

I have an table with file names with complete path.

select * from t_file_log

1 C:\Load\file1.csv

2 C:\Load\file2.csv

=====================

I have an folder with below files 

file1.csv ,file3.csv, file4.csv

=====================

I want to create an package where i can find the file names not in table, present in folder and insert record into table of the files.

======================

Result

====

select * from t_file_log

1 C:\Load\file1.csv

2 C:\Load\file2.csv

3 C:\Load\file3.csv     -- Row added via pacakge

4 C:\Load\file4.csv   -- Row added via pacakge

I need to do this using for each loop. avoid any batch file.

My Requirement is getting the file names from folder into SQL table.
