# Assume file names are like ThatShow - S01E03
# Assume they will go in their respective subfoders in a directory called Media (M:\Media)
$ParentPath = 'M:\Media'
# Get collection of .mp4 files from working directory
$files = Get-ChildItem *.mp4
foreach ($file in $files) {
    # Parse the title from the file name
    $ShowTitle = $file.Name.Split('-')[0].TrimEnd()
    # Parse the season from the file name
    $Season = "Season " + [decimal]$file.Name.Split('-')[1].TrimStart().Substring(1,2)
    # Put it all together
    $Path = "$ParentPath\$ShowTitle\$Season"
    # Move it
    Move-Item $file $Path
