I'm fairly confident that PAR::Packer doesn't meddle with the files in the cache area of a pp-packed executable. AFAICT there's nothing in the code to delete files there (except to purge the whole cache area immediatly after running the executable). At least for *nix installations I can think of an explanation: administrative cron jobs that clean up /tmp, /var/tmp etc by purging files not modified for some time. Dunno for Windows, esp. since the "temp" directories there are typically specific to each user. Cheers, Roderich
