Best way to set a files modified datetime

[davepile]

I am having issues each way I try to do something so hoping someone could recommend the best way to approach this fairly simple task

I am processing a file list that i retrieved using

$fileList = Get-PnPFolderItem -FolderSiteRelativeUrl $ipFolder -ItemType File

For some items I need to set the modified datetime as I loop through the results
foreach($file in $fileList){

I cant seem to find a way to do this using the $file item

I have seen solutions using Set-PnPListItem
So I fetch my list
$listItems = Get-PnPListItem -List $ListName -PageSize 500

But there are 100k list items and apart finding my one file being inefficient, I cannot find the property names corresponding to the folders etc to find the file

When I use $listItems = Get-PnPListItem -List $ListName -PageSize 500 # -FolderServerRelativeUrl '/sites/Intranet/Shared Documents/xxx/yyy I get an error
Get-PnPListItem : The attempted operation is prohibited because it exceeds the list view threshold

Hoping someone can point me in the right direction

I found what I was looking for.

As mentioned in the question I was processing a $fileList obtained using Get-PnPFolderItem

The solutions for changing the file modified date all used a list item.

I was already using Get-PnPFile but hadn't noticed the -AsListItem option

Anyway this worked for me

 foreach($file in $fileList) { 

      $listItem = Get-PnPFile -Url $file.ServerRelativeUrl -AsListItem

      Set-PnPListItem -List 'Documents' -Identity $listItem.Id -Values @{"Modified"=$dt; } # | Out-Null
  }
