移动使用昨天时间戳创建的所有文件--POWERSHELL

Question

我试图移动今天（1天）（昨天）创建的所有文件。我不知道什么是错的，因为当我设置$ which_day为-1时我得到了没有找到的文件＆＃39;但是当我将$更改为0时，所有文件都会被移动。

###############PAR#############
$which_day = -1 
$filter = "*.*"  
$path = "E:\log_test"  
$path_destination = "E:\yesterday_log" 

$save_log = 1 
$path_log_folder = "E:\yesterday_log"  
$logname = "$path_log_folder\MOVED_FILEsLog_$(get-date -Format "yyyy-MM-dd_HHmmss").txt" 
######################################


$limit_from =  (Get-date (Get-date -Format d)).AddDays($which_day) 
$limit_to = (Get-date (Get-date -Format d)).AddDays($which_day + 1) 

$files_to_copy = Get-ChildItem -Path $path -include $filter -Recurse | Where {$_.CreationTime -ge $limit_from -and $_.CreationTime -lt $limit_to} 
$files_to_copy | Select Name, Directory, LastWriteTime  
Write-Host $files_to_copy.Count "files were found"  
$ID=1
$OK=0
$NOK=0
Foreach ($file_to_copy in $files_to_copy){
    $file_path = $file_to_copy.FullName
    $file_path = $file_path.Replace($path,"")
    $destination_file_path  = $path_destination + $file_path
    $destination_file_path = $destination_file_path.Replace($file_to_copy.Name, "")
    $destination_file_path = $destination_file_path.Substring(0,$destination_file_path.Length-1)
    $destination_file_path
    if (!(Test-Path -Path $destination_file_path)){New-Item $destination_file_path -Type Directory}
    Move-Item -Path $file_to_copy -Destination $destination_file_path -force

        if (Test-Path $file_to_copy) #check if moved
            {
                $NOK++
                "$ID WARNING: File $file_to_copy NOT MOVED" | Out-File -FilePath $logname -Append 
            }
        else {
                $OK++
                "$ID INFO: File $file_to_copy MOVED OK to $destination_file_path" | Out-File -FilePath $logname -Append 
            }
        $ID++
}
$Quantity = $files_to_copy.Count
If ($save_log = 1)
{
    "***************************************" | Out-File -FilePath $logname -Append #SUMMARY
    "$Quantity files were Found" | Out-File -FilePath $logname -Append #ALL FILES
    "$OK files OK MOVED" | Out-File -FilePath $logname -Append #MOVED FILES
    "$NOK files NOT MOVED" | Out-File -FilePath $logname -Append #UNMOVED FILES
}
