How to copy file based on matching file name using PowerShell?
But I want to do limitation while I copy a file from 1st folder. I will NOT copy the file, if I already copy the same file from 1st folder to 2nd folder 3 times.
This is the code from the reference.
$Job_Path = "D:\Initial"
$JobError = "D:\Process"
Get-ChildItem -Path "$OpJob_Path\*\*.jpg" | ForEach-Object {
$basename = $_.BaseName.Substring(15)
$job = "$Job_Path\${basename}.png"
if (Test-Path $job) {
$timestamp = Get-Date -Format 'yyyyMMddhhmmss'
$dst = Join-Path $_.DirectoryName "${timestamp}_${basename}.gif"
Copy-Item $job $dst -Force
}
Anyone can help me to solve this problem please. Thank you.

$timestamp = Get-Date -Format 'yyyyMMddhhmmss'
$dst = Join-Path $_.DirectoryName "${timestamp}_${basename}.gif"
$Get = (Get-ChildItem -Name "$OpJob_Path\*\*$basename.jpg*" | Measure-Object).Count
$Get
if ($Get -eq "3") {
Write-Host "Continue Other Process"
NEXT_PROCESS
} else {
Write-Host "Less than 3"
}
Copy-Item $job $dst -Force
}

$Get is not a hashtable, and it's also not keeping track of what's been copied already. You need to define the hashtable outside the loop
$copy_count = #{}
Get-ChildItem -Path "$OpJob_Path\*\*.jpg" | ForEach-Object {
...
}
and then update it whenever you copy a file
if ($copy_count[$_.Name] -le 3) {
Copy-Item ...
$copy_count[$_.Name]++
} else {
...
}
