PowerShell for finding the size of your local OneDrive folder

I would just like to share a couple of PowerShell scripts to find the size of your local OneDrive folder. Note that this just looks at folders structures and does not interact with the OneDrive sync client or the OneDrive service.

First, a one-liner to show the total files, bytes and GBs under the local OneDrive folder (typically C:\Users\Username\OneDrive):

$F=0;$B=0;$N=(Type Env:\UserProfile)+"\OneDrive";Dir $N -R -Fo|%{$F++;$B+=$_.Length};$G=$B/1GB;"$F Files, $B Bytes, $G GB" #PS OneDrive Size

Second, a slightly longer script that shows files, folders, bytes and GBs for all folders under the profile folder that starts with “One”. That typically includes both your regular OneDrive folder and any OneDrive for Business folders:

$OneDrives = (Get-Content Env:\USERPROFILE)+"\One*" 
Dir $OneDrives | % {
   $OneDrive = $_
   Dir $OneDrive -Recurse -File -Force | % {
       $Bytes += $_.Length
   $Folders = (Dir $OneDrive -Recurse -Directory -Force).Count
   $GB = [System.Math]::Round($Bytes/1GB,2)
   Write-Host "Folder ‘$OneDrive’ has $Folders folders, $Files files, $Bytes bytes ($GB GB)"

Here is a sample output of the code above:

Folder ‘C:\Users\jose\OneDrive’ has 4239 folders, 33967 files, 37912177448 bytes (35.31 GB)
Folder ‘C:\Users\jose\OneDrive-Microsoft’ has 144 folders, 974 files, 5773863320 bytes (5.38 GB)
