I'd like to write a file/folder sniffer in VFP and was wondering if there might be a class out in public domain that already does this.

I'd like this sniffer to be able to poll folders on a server and when certain files are found, it should be able to move them to; say, backup folders and insert the file contents into SQL tables.

How would I prevent this sniffer program from using 100% of the CPU on the server. And would it be better to create it as an executable or DLL?

Thanks for the help.
