Yup. Make a list of all the file names, write a key function that extracts the numbery bits, sort the list based on that key function, and go to town.
Is it necessary to sort them? If XXX is known, then presumably the first file will be called XXX_chunk_0, the next XXX_chunk_1 and so on.
It would be possible to iterate over such a sequence of filenames, and keep opening them then writing them to the output until there are no more files. Or, if a list of matching files is obtained, the length of the list will also give you the last filename.
(But this won't work if there are gaps in the sequence or the numeric format is variable.)
