Enhance logging format for powershell output

Hey Experts!  As I evolve my script, I wanted to improve the log file format.  I need to help with the programming portion.  

Right now the script will delete the files that meet the criteria set and output basic info to a log file.

$logfile = "C:\Tools\Logs\SW_Cleanup.log"
cd "C:\tools\Scripts\Test"

forfiles /d -0 /c "cmd /c echo @path @fdate" > $logfile
forfiles /d -0 /c "cmd /c del /q /f @file"

Open in new window


I would like to include a header like this:

$scriptversion = 10.12.18


Add-Content -Path $sFullPath -Value "Started processing at [$([DateTime]::Now)]."
Add-Content -Path $sFullPath -Value "***************************************************************************************************"
Add-Content -Path $sFullPath -Value ""
Add-Content -Path $sFullPath -Value "SpiceWorks purge of backups older than 10 days"
Add-Content -Path $sFullPath -Value ""
Add-Content -Path $sFullPath -Value "Running script version [$ScriptVersion]."
Add-Content -Path $sFullPath -Value ""
Add-Content -Path $sFullPath -Value "***************************************************************************************************"
Add-Content -Path $sFullPath -Value "

Through my testing, I've tried various add-content and write-log options with no success so I figured it was time to ask the professionals.  I appreciate your time and assistance.

I used -0 days so that I could test out the script and delete out any files 0 days old (essentially all).  I'm changing it back to -10 so it will only delete those files that are older than that.

Actually going to take parts out of your script and incorporate into mine so I thought it only fair to include you in the answer process.  Thank you for your time and script!
