Files Older Than 3 Months Combined Total File Size

A requirement to identify the total file size of all files not used in the last 3 months.

This was the solution

#Run as administrator
#You need to have permission of the files or folders 

$date = (Get-Date).AddMonths(-3)

dir C:\temp -Recurse | ?{$_.lastwritetime -lt $date -and !$_.PsIsContainer} | Measure-Object -Property Length -Sum

# oneliner

dir C:\temp -Recurse -Force -ErrorAction SilentlyContinue | `

    ?{$_.lastwritetime -lt (Get-Date).AddMonths(-6)} | Measure-Object -Property Length -Sum -ErrorAction SilentlyContinue


# resulting data will be in bytes. To convert them to gigabytes, you may do this:

$files = dir C:\temp -Recurse -Force -ErrorAction SilentlyContinue | `

    ?{$_.lastwritetime -lt (Get-Date).AddMonths(-6)} | Measure-Object -Property Length -Sum -ErrorAction SilentlyContinue

($files.sum / 1gb).ToString(“F02”)

# F02 determines how much digits will appears after comma. In my case – 2 digits.


dir C:\temp -Recurse | ?{$_.psiscontainer} | %{

    Write-Host current folder is $_.fullname;

    dir $_.fullname | measure-object -property Length -sum -ErrorAction SilentlyContinue

} >c:\temp\file sizes

vSphere ESXi 6.7 Unable to talk between subnets between hosts

Configuration was :

ESXi 6.7 – vSphere handling all the port groups tagged with VLANs

Firewall – CISCO ASA


Problem : New ESXi 6.7 hosts. A virtual machine if on the same host and vSwitch could communicate no problem. However if a virtual machince was communincating with another virtual machine on another host on a different, subnet they were unable to communicate between subnets and hosts. Both virtual machines could ping their local gateways. Firewall, CISCO ASA was just dropping all packets and showing the following error

Error on the Firewall when capturing ping traffic “No source port  on ping “Error (Type 8, Code 0), Denied ICMP type=8, code=0”



Sometimes its the simple tick box on the Firewall / ASA config

“Enable traffic between two or more interfaces which are configured with the same security levels”

All traffic started communicating and the virtual machines could talk between the subnets as per the rules on the Firewall.
