Powershell gives Get-Content : Exception of type 'System.OutOfMemoryException' was thrown

Question

I am trying to read file of size 1 GB as bytes in powershell using below command,

$data = Get-Content -Encoding byte $filepath

It throws below error : Get-Content : Exception of type 'System.OutOfMemoryException' was thrown.

Searched net and found that running below command fixes it however this is not working for me. set-item wsman:localhost\Shell\MaxMemoryPerShellMB 4096

Answer 1

By default MaxMemoryPerShellMB = 1024MB If you want to read large file say 1GB or greater than that, You need to set MaxMemoryPerShellMB.

Use below code to set MaxMemoryPerShellMB-

    function setpsmem
    {
          $winrmstatus = (get-service WinRM).Status
         if ($winrmstatus -eq 'Running')
    {
        $currentpsmem = (Get-Item WSMan:\localhost\Shell\MaxMemoryPerShellMB).value
        if ($currentpsmem -le 4096)
        {            
            Set-Item WSMan:\localhost\Plugin\Microsoft.PowerShell\Quotas\MaxMemoryPerShellMB 4096
            Set-Item WSMan:\localhost\Shell\MaxMemoryPerShellMB 4096
            Restart-Service winrm
            $currentmemory = (Get-Item WSMan:\localhost\Shell\MaxMemoryPerShellMB).value
            Write-Host "Script assign $currentmemory[MB] of memory to PowerShell" -ForegroundColor Green
        } 
        else
        {
            $currentpsmem = (Get-Item WSMan:\localhost\Shell\MaxMemoryPerShellMB) | Select-Object value
            Write-Host "Powrshell has $currentpsmem[MB] of memory." -ForegroundColor Green
        } 
    }
    else
    {
        Write-Host "WinRM services is not running on current host." -ForegroundColor Red
    }

} setpsmem

Try it.
