Powershell program to upload multiple files with version control at the file level

Question

I have a network folder which contains multiple files refreshed daily.I then run a power
shell scrip which uploads all the files . I have scheduled it to run once
daily. I have version control at the directory level , is there a way to upload all the files daily and maintain the last X versions for each file , rite now it does it at a folder level . I want it at a file level
powershell script
if((Get-PSSnapin "Microsoft.SharePoint.PowerShell") -eq $null)
Add-PSSnapin Microsoft.SharePoint.PowerShell
#Script settings
$webUrl = "http://sharepoint.contoso.com/Corporate/Sales/"
$docLibraryName = "Shared Documents"
$docLibraryUrlName = "Shared Documents\arizona" # specify your subfolder url here
$localFolderPath = "C:\Test"
#Open web and library
$web = Get-SPWeb $webUrl
write-host $webUrl
$docLibrary = $web.Lists[$docLibraryName]
write-host $docLibrary
$files = ([System.IO.DirectoryInfo] (Get-Item $localFolderPath)).GetFiles()
write-host $files
ForEach($file in $files)
if($file.Name.Contains(".pdf"))
write-host $file
#Open file
try
$fileStream = ([System.IO.FileInfo] (Get-Item $file.FullName)).OpenRead()
#Add file
$folder = $web.getfolder($docLibraryUrlName)
write-host "Copying file " $file.Name " to " $folder.ServerRelativeUrl "..."
$spFile = $folder.Files.Add($folder.Url + "/" + $file.Name,[System.IO.Stream]$fileStream, $true)
write-host "Success"
#Close file stream
$fileStream.Close();
catch
Write "Error: $file.name: $_" >>c:\logfile.txt
continue;
#Dispose web
$web.Dispose()
