Bulk rename

Naming convention

• yyyyMMdd_HHmmss for original media
• yyyyMMdd_HHmmss crop for cropped media
• yyyyMMdd_HHmmss edit for adjusted media

Standardize file name

Rename movies to yyyyMMdd_HHmmss

$i = 0
gci -Filter "*.MOV" |
% { 
    [string]$newName = ($_.CreationTime).ToString("yyyyMMdd_HHmmss") + " " + $i++ + $_.Extension
    Rename-Item -Path $_ -NewName $newName
}

Standardize pictures name

function Rename-Pictures {
    $index = 1
    $files = Get-ChildItem -File -Filter "*.jpg"
    $files | foreach {
        Rename-Item -Path $_ -NewName "_$($_.Name)"
