Is there a cmdlet or property that will show when a file was last loaded by an application

Hi

I'm trying to learn more about the software that my company has written - like knowing which dlls are called when the user goes into various menu. I could speak to a Developer to ask everytime but they would get annoyed after a while.

I've written this kind of script but the property does not show when the file was last accessed by the PC.

Get-ChildItem -path 'C:\Program Files (x86)\My Company\modules\*' | Select FullName,LastAccessTime | Sort-Object LastAccessTime

I need to know so I can double check the the relevent dll files are intact/up to date.

Can anyone help :-

Thanks

Matt
