Setting up timer on Polled Folder

PowerShell Help
1

I have created code that will allow for a folder being polled constantly, to monitor for changes in a file such as copy, delete, rename, etc.

I have also included code for a Wait-Function that I am trying to get working. The problem is that I need the script to only poll for a limited period of time and then take the changed files, if any, and move them to a different drive/ shared folder on the network.

Here is what I have so far. Any help would definitely be appreciated.

Thank you.
