How to create a brunch of files with fixed size at once?

Question

Hi guys, for test proposes I want to create a bunch of files with fixed size. This is how far I got

(1..10) | ForEach-Object {New-Item -Name "New-File$_.txt" -ItemType File -Path ".\Test" } 

I could not figure out a way to set the size of each .txt file so I asked Google. Here is what I found:

$file = New-Object System.IO.FileStream ".\Test\New-File.txt", Create, ReadWrite
$file.SetLength(10m)
$file.Close()

Above script creates a 10mb .txt file. I`m struggling to find a way to integrate it in a loop. May I ask you for help?

Hello Marin.

This PowerShell snippet creates a set of 10 files of 100 Kilobytes each, giving a unique name to each file.

For ($i=1; $i -le 10; $i++)
{
  $FileName = "File"+$i+".txt"
  Write-Host $FileName
  $file = New-Object System.IO.FileStream $FileName, Create, ReadWrite
  $file.SetLength(100Kb)
  $file.Close()
}

You can take it as a reference.

Bye.

Hello Luigi, thank you for you answer! It helped me to write the script I needed. Here is the final result:

Write-Host "I will create for you a bunch of files!" -ForegroundColor Yellow
$date = Get-Date -Format dd-MM-yyyy
$numb = Read-Host -Prompt "How many files do you want me to create?" 
$size = Read-Host -Prompt "How big do you want to be each file?"


For ($i=1; $i -le $numb; $i++)
{
  $file = New-Object System.IO.FileStream  ".\Test\$date-File-[$i].txt", Create, ReadWrite
  $file.SetLength($size)
  $file.Close()
}

By the way, any idea how I can change the path based on user`s input ($path = Get-Host "type path")?
