Hey!

Another question just came up. In order to control my processing process with a lot of files I'd like to create two lists (txt.'s). One list contains the properly processed (ok_list) and one list the corrupt files(error_list). Based on an exitcode from my processor I'd like to write the name of the currently processed file into the correct list.

The only problem I have here is that e.g. if 2 files are correctly processed the first line of my ok_list should not be overwritten. How do I manage to do that?
