The issue is that I need to be able to both, split the names of the files so that I can extract the relevant times, and open each individual file and process each line individually. Once I have achieved this I need to append the sorted files onto one another in one long file so that I can pass them into a verification package. I've tried changing the name to textline and I get the same result - the sorted files overwrite one another. The data are actually meteorological observations and I need to manipulate them in order to test the performance of a model. The 333 denotes that cloud observations are going to follow - something that is not always reported at stations.
