FileSystemWatcher and copy file

Question

1) i am using FileSystemWatcher to get an event when a new file is copied to my monitored folder.
the problem is, that i want to copied this new file, but if its 100MB file, i will get an error that the file is in use! - os there a way to check that the file has finished coping before it try to copy it?

2)i am holding an array of instances of FileSystemWatcher , and i want with each instance that i put in the array to save some more data - how can i do it?

What I do for things like this when it is possible is to write code that shows all possibilities. Have you done that? Have you set the NotifyFilters enumeration so taht you see all possible change types? You need to get all possible notifications for diagnostic purposes and then when you have figured out what notifications are relevant then you can modify the program to minimize the notifications to just the ones you need.
