I'm wondering if a program exists that can monitor the size of files to which it's pointed and then generate alerts once they hit a specified threshold. I'm thinking PST files specifically, but a general-purpose utility would be fine as well.

Alternatively, are there any server-side apps that would do something like this and then auto-Email sysadmins when a file grows too large?

Thanks for any help you can provide.

And, there are several 3rd party applications for quota management as well.
