How Can I Run a PowerShell Script Recursively in OneDrive?

I ended up writing my own recursive function using PnP to fetch the data directly. Something like this worked for me:

```powershell
Get-PnPFolderItem -FolderSiteRelativeUrl $newFolderURL -ItemType File
Get-PnPFolderItem -FolderSiteRelativeUrl $FolderURL -ItemType Folder
```
It’s a bit of an extra setup, but it can be effective!

As someone else pointed out, the issue might be that you're trying to access shortcuts instead of actual files. I'd recommend using the OneDrive API or Power Automate to get the file hashes, which would bypass the issues with local syncing.

OneDrive often stores files as shortcuts unless you set them to be fully downloaded. Make sure to enable 'Always keep on this device' for the folder. I did that, and it allowed my script to access the subdirectories without issues. Otherwise, if the files aren’t fully downloaded, you’ll hit a wall when trying to get their hashes.

You could also look into the Graph API to retrieve file hashes directly, which would save you from doing the calculations manually. Here's the link: https://learn.microsoft.com/en-us/graph/api/resources/hashes?view=graph-rest-1.0.

If you simplify your function by removing the `$isDirectory` check, you could streamline your code. Here's a quick version that worked for me:

```powershell
function GetFileHashes ([string]$rootLocation) {
if ((Test-Path -LiteralPath $rootLocation -PathType Container -ErrorAction Stop)) {
$hashList = Get-ChildItem -Path $rootLocation -Recurse -Force -File | Get-FileHash
} elseif ((Test-Path -LiteralPath $rootLocation -PathType Leaf -ErrorAction Stop)) {
$hashList = Get-FileHash -LiteralPath $rootLocation
} else {
throw "Path not found: $rootLocation"
}
return $hashList
}
```
This version gets the hashes correctly across OneDrive for me.
