If you want to quickly replace all spaces (or other charachters) in a number of files you use the Get-ChildItem Cmdlet in conjunction with ForEach-Object:

Test the script

If you want to test the script without acctually changing anything you can use the -WhatIf switch:

Get-ChildItem -Recurse | Where-Object { $_.Name -match '\s' -and (-not($_.psIsContainer))} | ForEach-Object { ren $_.fullName ($_.Name -replace '\s', '-') -WhatIf}

The -WhatIf switch will instruct the script to only print out what it would do:

Execute the script

To execute the script just move to the directory which contains the file files you want to rename and paste the following command in your PowerShell console:

Get-ChildItem -Recurse | Where-Object { $_.Name -match '\s' -and (-not($_.psIsContainer))} | ForEach-Object { ren $_.fullName ($_.Name -replace '\s', '-')}
