robocopy Mirror a source directory to a destination, including subdirectories and empty ones

robocopy C:\SourcePath D:\DestinationPath /MIR /DCOPY:T /MT:8 /R:3 /W:1 /NP /LOG:C:\robocopy.log

rsync via WSL to sync files from a Windows path to another

wsl rsync -av /mnt/c/SourcePath /mnt/d/DestinationPath

Compare two folders

$folder1Items = Get-ChildItem -Path "C:\Folder1" -Recurse
$folder2Items = Get-ChildItem -Path "C:\Folder2" -Recurse
Compare-Object -ReferenceObject $folder1Items -DifferenceObject $folder2Items -Property Name, Length

Check size force

Compare-Object -ReferenceObject $folder1Items -DifferenceObject $folder2Items -Property Name, Length | Where-Object {$_.SideIndicator -eq "<="} | Copy-Item -Destination "C:\Folder3" -FromPath "C:\Folder2" -Force
