Heh, well, if I knew C or C++, I'd definitely personally tackle it. And how
files are added is relatively immaterial in general retrospect, as the idea is
only to purge files by number of files, removing the oldest one. By using, as I
mentioned, the uploaded date in the database, it doesn't matter if the file was
uploaded by direct Zmodem upload, FTP upload, or addfiles utility, etc.. So
long as the database details are correctly maintained..
This could need two basic changes in general. One, a toggle in the
configuration allowing to enable purging files by number, as it is now, that
may not be desired in every file base, but every file base setting does have
the max files option in it, and default to 10000 or so. Unless simply setting
that to 0 would disable purging would suffice, a flag needs to exist for
delfiles to be told to handle it, or so.
And of course, modifying delfiles itself to do the process accordingly.
