PowerShell script to zip files inside many folders recursive - powershell

Question

I would like to go inside every folder recursive in some location,
for example: C:\Logs and zip files to the same folder.
I need to skip every .zip file. I don't know how to make my script to do this:
function New-Zip
{
param([string]$zipfilename)
set-content $zipfilename ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18))
(dir $zipfilename).IsReadOnly = $false
}
function Add-Zip
{
param([string]$zipfilename)
if(-not (test-path($zipfilename)))
{
set-content $zipfilename ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18))
(dir $zipfilename).IsReadOnly = $false
}
$shellApplication = new-object -com shell.application
$zipPackage = $shellApplication.NameSpace($zipfilename)
foreach($file in $input)
{
$zipPackage.CopyHere($file.FullName)
Start-sleep -milliseconds 500
}
}
$targetFolder = 'C:\Logs'
$now = Get-Date -Hour 0 -Minute 00 -Second 00
$days = 5
$lastWrite = $now.AddDays(-$days)
Get-ChildItem $targetFolder -Recurse -Exclude *zip* | Where-Object { $_ -is [System.IO.FileInfo] } | ForEach-Object {
If ($_.LastWriteTime -lt $lastWrite)
{
$_ | New-Zip $($targetFolder + $_.Name + ".zip" )
$_ | Add-Zip $($targetFolder + $_.Name + ".zip" )
}
}

You are currently excluding any file or folder that contains the phrase 'zip' in its name as you have a wildcard either side of it:
Get-ChildItem $targetFolder -Recurse -Exclude *zip*
To exclude zip files you just need to update your Exclude statement so that it matches only the zip file extension:
Get-ChildItem $targetFolder -Recurse -Exclude *.zip
