Check if a certain file has been updated in last X days and error if is hasn't

Question

I need to test if a file has been updated within the last few days (it's updated monthly) and proceed if so, but error if it hasn't been updated.
I used the following to check if the file has been updated:
Get-Item c:\temp\junk.txt | Where{$_.LastWriteTime -gt (Get-Date).AddDays(-7)}
It returns the file:
But I couldn't get that to work in a If/Else statement, so I tried Test-Path:
$path = "c:\temp\junk.txt"
If(Test-Path -path $path | Where{$_.LastWriteTime -gt (Get-Date).AddDays(-7)})
"File exists"
Else
{“No file” }
Although this always returns "No File".
Any idea what I'm doing wrong??

Hi,
Here's how I'd do something like that:
If ((Get-Item c:\temp\junk.txt).LastWriteTime -gt (Get-Date).AddDays(-7)) {
Write-Output 'Less than 7'
Else {
Write-Output 'Too old'
