StampMe.ps1

Rename a file or a folder by appending the current date and time to the existing file or folder name:

#StampMe.ps1
param( [string] $fileName)

# Check the file exists
if (-not(Test-Path $fileName)) {break}

# Display the original name
"Original filename: $fileName"

$fileObj = get-item $fileName

# Get the date
$DateStamp = get-date -uformat "%Y-%m-%d@%H-%M-%S"

$extOnly = $fileObj.extension

if ($extOnly.length -eq 0) {
   $nameOnly = $fileObj.Name
   rename-item "$fileObj" "$nameOnly-$DateStamp"
   }
else {
   $nameOnly = $fileObj.Name.Replace( $fileObj.Extension,'')
   rename-item "$fileName" "$nameOnly-$DateStamp$extOnly"
   }

# Display the new name
"New filename: $nameOnly-$DateStamp$extOnly"

Examples

Assuming stampme.ps1 is saved in the current directory:

PS C:\>./stampme.ps1 "F:\work\some file.txt"

  > F:\work\some file-2009-11-30@09-30-00.txt

Rename a collection of .txt files:

foreach ($file in get-ChildItem *.txt) { ./stampme.ps1 $file.name }
