Vista - Copy/Move file and rename if destination exist

Hi,

I'm trying to get better with Powershell, and I just want your
comments on this little function I wrote, to automatically rename a
files (with increment) if the destination file already exists when I
try to copy or move a file.

I'm just wondering, if there is a faster/cleaner way to write this
function

Example: I want to copy a file from "c:\source\test.txt" to "C:
\test", so I'm checking if "c:\dest\test.txt" doesn't exist, and it it
does the source will will be renamed to test[1].txt

function rename_exist_file([string]$source, [string]$dest) {
cls
$fullname=[io.path]::GetFileName($source)
$name=[io.path]::GetFileNameWithoutExtension($source)
$ext=[io.path]::GetExtension($source)
$dir=[io.path]::GetDirectoryName($source)
$newfile="$dest\$fullname"

$i=1
while ((test-path -literalpath $newfile)) {
#write-host -back blue -for white $newfile already exists
$newfile = $dest + '\'+ $name +'['+ ($i++) +']' + $ext
}

$newfile
}

$source= "c:\source\test.txt"
$dest="C:\dest"

Copy-Item -LiteralPath $source -destination (rename_exist_file $source
$dest)

Hi Personne,

I will purpose a solution more easy, by using CMDLET directly....


function CopyFileToFolder ([string]$Source,[string]$destination){

$filename = $source.substring($source.lastindexofany("\") +1 ,$source.length
- ($source.lastindexofany("\")+1))
if (Test-Path $destination$file) {
$ext = Get-Date -format 'yyMMddhhmmss'
Rename-Item $destination$filename $ext"."$filename
}
Copy-Item $source $destination
}

$sourcefilepath = "P:\SNCF powershell\temp\test.txt"
$destinationpath = "P:\SNCF powershell\temp\test\"
copyFiletoFolder $sourcefilepath $destinationpath

I wish it will help you
