Thanks for the response, guys. I'm pleased that I don't have to write such a thing from scratch, Especially as I'm fairly new to Perl!
Well, when I've been manually testing the file processing, it hasn't taken much time (20->30secs). And I'm not expecting much traffic, so I can take it easy with the programming for now! However on a later project, doing much the same thing, _that_ will be more of a challenge (more traffic, huge audio files, lots of directories), so thanks for the pointers!

It does of course work on Win2k and WinXP. I woud not recommend using srvany.exe though. It's much better to use either ActiveState's PerlSvc (pert of Perl Dev. Kit) or Dave Roth's Win32::Daemon ( should be instalable via PPM ) There's another thing ... if the processing of the files takes a lot of time it might be better to use two threads. One that would watch the directories, the other that would process the files. You do not need a lot of synchronization in this, a single one-way pipe should be enough. Jenda P.S.: I made a service that translates our ASPs and web pages for multilingual websites that does just this. One thread watches the directories and tests the service status and sends commands like "directory X changed", "reload initfile", "check for updated translations" and "quit" to the worker thread. You might find handy my Win32::BiggerPipe ( http://jenda.krynicky.cz/perl/BiggerPipe.pm ) in case the processing takes long and the changes happen too often. =========== [EMAIL PROTECTED] == http://Jenda.Krynicky.cz ========== There is a reason for living.
