Vista - compare-object

I wrote this function and it takes two params. One to the source dir
and one to the dest. Think of it as a folder syncer that syncs source
to dest. It works great if the filenames are different or if the file
doesn't exist in either. However, if the files in the source and dest
have the same name but are actually different files it still sees them
as == which is wrong. It needs to treat them as different because they
are in fact different.


function foldermirror
{
param ($source, $dest)
$comparedirs = Compare-Object (gci $source) (gci $dest)
if ($comparedirs | Where-Object {$_.SideIndicator -eq '=>'})
{
$comparedirs | Where-Object {$_.SideIndicator -eq '=>'} |
ForEach-Object{Write-Host "Removing"($_.InputObject).FullName
Remove-Item ($_.InputObject).FullName}
}
if ($comparedirs | Where-Object {$_.SideIndicator -eq '<='})
{
$comparedirs | Where-Object {$_.SideIndicator -eq '<='} |
ForEach-Object{Write-Host "Copying"($_.InputObject).FullName "to"
$dest
Copy-Item ($_.InputObject).FullName -Destination
$dest}
}
else
{
Write-Host "The directories are the same"
}
}
