I've got a ton of files scattered across many subfolders organized by year, month, and day. When I try to move them into one folder for processing, I run into an issue: there are over 100 files with duplicate names like doc.pdf. Is there a way in PowerShell to automatically rename these duplicates? Ideally, I'd want the first one to be renamed to doc001.pdf, the second to doc002.pdf, and so on. I'm really not picky about the final names; I just need to avoid any duplicates.

I plugged your question into a scripting assistant, and it gave me a great script! Here’s a simplified version:
```powershell
$sourceFolder = "C:pathtoyoursourcefolder"
$destinationFolder = "C:pathtoyourdestinationfolder"
$counter = 1
# Create destination folder if needed
if (-not (Test-Path -Path $destinationFolder)) {
New-Item -ItemType Directory -Path $destinationFolder
}
# Move and rename files
Get-ChildItem -Path $sourceFolder -Recurse -File | ForEach-Object {
$newFileName = "{0}{1:000}{2}" -f $_.BaseName, $counter, $_.Extension
Move-Item -Path $_.FullName -Destination (Join-Path -Path $destinationFolder -ChildPath $newFileName)
$counter++
}
```
Just make sure to replace the folder paths with yours! This will move and rename all duplicates automatically. Let me know if you need any tweaks or have questions! 😊
If you're looking for a reliable method, you might want to consider using file hashes. With `Get-FileHash`, you can ensure that each file is uniquely identified by its content rather than just its name. A downside is it might slow down your script if you’re dealing with large files, but the upside is you avoid having multiple identical files in your folder. If you’ve got a lot of duplicates in terms of content, this approach might save you some hassle later on!
But be cautious: Windows can struggle with handling too many files in a single folder, especially if we're talking tens of thousands. You wouldn't want to overwhelm your system!
Thanks for the heads up! I know how unstable Windows can get with large file counts—I've got a legacy system with over 7 million files in one folder. Luckily, my process only dumps 1500-2500 files at a time into the watch folder.
I managed to whip up a quick line of PowerShell that should work for your needs! You can use this:
`Get-ChildItem doc.pdf -Recurse | %{Rename-Item $_ -NewName ('doc_{0:D4}.doc' -f $i++)}`. This will search recursively for each instance of doc.pdf and rename it sequentially. Just make sure to initialize your counter variable ($i) before running the line! That should help tackle those duplicates easily.
I'm curious why more of us aren't using AI tools for tasks like this! They can save so much time.
