Copy files which are complete? - powershell

Question

While running a command to copy files from source to destination using powershell, I ran into the problem of how to only copy files which do not have any operation running on them?
If there are 3 files A/B/C, logging is still happening on A, while B and C are complete. I only want to copy B and C using powershell.
Any ideas will be helpful.

Here is something you can start with:
function Test-FileNotInUse
{
[cmdletbinding()]
param(
[parameter(Position = 0, Mandatory = $true, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true)] [Alias('FullName')] [string] $filePath
)
process {
$inUse = $false
try {
$fileInfo = New-Object System.IO.FileInfo $filePath
$fileStream = $fileInfo.Open([System.IO.FileMode]::OpenOrCreate, [System.IO.FileAccess]::ReadWrite, [System.IO.FileShare]::None)
if ($fileStream) {
$fileStream.Close()
}
}
catch {
$inUse = $true
}
if (!$inUse) {
Write-Output $filePath
}
}
}
$source = "C:\source"
$destination = "C:\destination"
dir $source -recurse | Test-FileNotInUse | %{ copy $_ $destination }
