I don't "want" but I definitely "have to" because (parts of) the file
names are used in multiple places; some comments printed onto the page
are derived from the names as well as bookmark entries when a new month
begins (the date is encoded within the file name).

Well, the difference is quite obvious. Judging from the observed
behaviour the string object "filenameforall" uses apparently isn't
handled on the stack but elsewhere in "virtual memory".

I don't know any file system internals. The "Windows Explorer" is able
to sort the data using a lot of file attributes in ascending and
descending order. Using "dir" from the "DOS prompt" doesn't result in
alphabetical ordering at all.
