Script Powershell to compress old files in one zip file

Question

Hello,

I need a script to compress files from the last 30 days in one zip file. I have this code that do the same but create one file for every single file:

## Adding 7zip to environment variables.
$7zippath = "$env:ProgramFiles\7-Zip\7z.exe"
Set-Alias 7zip $7zippath

## Replace x with the number of days before which the files have to be compressed.
$LastWrite = (get-date).AddDays(-30)
$date = (Get-Date).ToString('yyyyMMdd')

## Replace Path and Filter as per your need.
$Files = Get-ChildItem -Path "D:\LOGS" -Recurse -File | Where-Object {$_.LastWriteTime -le $LastWrite}


ForEach ($File in $Files) {
"Compressing Log $File"
7zip a "$($File.fullname)$date.zip" "D:\LOGS\$File"

if((Test-Path "$($File.fullname)$date.zip"))
{
"Log Compression succeeded, so deleting D:\LOGS\$File"
Remove-Item -Path "D:\LOGS\$File"
}
else
{
"Log Compression FAILED, Please check parameters are passed correctly"
}
}
```I dont know how can i zip all this files in one zipfile and name it as the last day of the month.  
  
Thanks,

Answer 1

If each file in your "$Files" variable has a distinct name, then you'll create a new archive file for each of them. That's just the way you wrote the 7zip command line parameters!

If your intention is to add all the files in the $Files variable to a new (or existing) archive you should probably specify the archive name outside the ForEach loop.

Hello,

I think one of the solution could look like following:

• create Archive folder - New-Item -Path <path> -ItemType Directory
• move all related files to this folder
• use Compress-Archive - examples of usage here compress-archive
• delete folder or files if not needed

Or you can limit it as much as possible by:

$Files | Compress-Archive -DestinationPath <path>   

Thank you.
