Create Backdated test files

CreateBackDatedFiles.ps1

# This script creates a series of text files and back-dates the createTime, modifiedTime and accessedTime. 
# I wrote it to test deleting of files X number of days old. It creates the following files:
# 1days.txt - which is 1 day old
# 2days.txt - which is 2 days old
# .... you get the idea. 

$destfolder = "C:\Users\{username}\temp";
$numFilesToCreate = 500;

For($i=1; $i -le $numFilesToCreate; $i++){
    $currentfile = $destfolder + '\' + $i + 'days.txt';
    
    #Create File
    Set-Content -Path $currentfile -Value 'test string'

    #Get File we just created
    $file = Get-Item $currentfile;

    #Reset Attributes
    $file.LastWriteTime = (Get-Date).AddDays($i * -1);
    $file.LastAccessTime = (Get-Date).AddDays($i * -1);
