PS script won't delete large file (1gb), only smaller files

Hey Experts.  Weird issue with a PS script.  It shows in the log file that the file(s) were deleted but yet they remain in the directory.  Yes I confirmed the right dir was being referenced and the correct date was being used.  Any reason why remove-item may not delete a file?  It didn't have a problem when I tested it on txt files that were 50k but now that I'm deleting files that are each 1GB+, the file isn't being deleted out.

Small portion of code

$deletedfiles = 0
$files = get-childitem -Path $path
$10days = (get-date).AddDays(-8)

foreach ($file in $files){
  if ($file.LastWriteTime -le $10days){
    remove-item -Path $file.fullname -Recurse -Force
    $log += "Deleted:" + $file.name
    $deletedfiles ++

  }
}
$log += "Deleted: " + $deletedfiles + " Files"

Select allOpen in new window

Shows the files as deleted but I verify they are still in the directory:

Deleted:spiceworks-backup-[V7.5.00091]-[2018-10-02].zip
Deleted:spiceworks-backup-[V7.5.00091]-[2018-10-03].zip

Thanks for your time and help!
