     It might help if you explained exactly what "one hour files" and
"one week files" are.  Hint, hint.

     I observe that this statement could not possibly produce the
output you claim (below).  I therefore conclude that your report
of "Here's what I did and here's what happened" is incorrect.

     Same remark: This statement could not possibly have produced the
output you reported.  You are lying to us -- perhaps innocently, but
you are lying nonetheless.

     Why bother with this?  It burns a few CPU cycles, chews
up a little bit of memory, and accomplishes nothing useful.

     ... except this is not the actual output, not from the code
you've shown at any rate.

     Others may (or may not) be more patient with you, but I for
one will offer no further help until:

     1) You define *precisely* what is meant by "one day files",
"one hour files" and "one week files,"

     2) You explain in more detail where the various files reside
and in what folders,

     3) You exhibit code and output (or error messages) that *match*.
