Windows - Powershell: How to output folder name, lastwritetime and folder size in one line?

You can use PowerShell to achieve this by using the Get-ChildItem cmdlet to retrieve information about folders, and then select the properties you want to display. You can then format the output to display the information in a single line.

Here's how you can do it:

Get-ChildItem -Directory | ForEach-Object {
    $_.Name + " | " + $_.LastWriteTime + " | " + "{0:N2} MB" -f ((Get-ChildItem $_.FullName -Recurse | Measure-Object -Property Length -Sum).Sum / 1MB)
}

Let's break down what this script does:

  • Get-ChildItem -Directory: This cmdlet retrieves all the directories (folders) in the current directory.
  • ForEach-Object: This cmdlet allows you to perform an operation on each directory returned by Get-ChildItem.
  • $_: Represents the current directory being processed in the loop.
  • Name: Retrieves the name of the directory.
  • LastWriteTime: Retrieves the last write time of the directory.
  • "{0:N2} MB" -f ((Get-ChildItem $_.FullName -Recurse | Measure-Object -Property Length -Sum).Sum / 1MB): This part calculates the total size of the directory (including subdirectories) in megabytes. It uses the Get-ChildItem cmdlet with the -Recurse parameter to get all files in the directory and its subdirectories, then pipes them to the Measure-Object cmdlet to calculate the sum of their lengths. Finally, it divides the sum by 1MB to convert it to megabytes and formats the output to display two decimal places.

This script will output each folder's name, last write time, and size in megabytes in a single line for each folder. You can adjust the formatting or add additional properties as needed.
