I am new to PowerShell and I get a lot done using this forum along with other internet searched answers but this one is getting the better of me. I have a script that compares two folders and the part where I'm having problems I cannot get the BitsTransfer source to work. $Differences identifies files from the source folder that are not in the target folder by modified date. I want the BitsTransfer to move the files identified by $Differences but I'm not having any luck getting that behavior. The operation works when I use "Copy-Item -Path $Differences -Destination $Local –Force" instead but i want the progress bar BitsTransfer Uses. The code i am using is as follows
$Local = 'c:\test\local\'
$Remote = 'c:\test\server\'
$Target = Get-ChildItem -Path $Local -File
$Source = Get-ChildItem -Path $Remote -File
Import-Module BitsTransfer
Set-Location $Remote
filter timestamp {"$(Get-Date -Format g): $_"}
if ($Target -eq $null) {
$bitsjob = Start-BitsTransfer -Source $Remote\*.* -Destination $Local
Write-Output "$Local Folder Empty" | timestamp | Out-File -Encoding Ascii -append "D:\Mitek\DCS Stuff\Display PC Scripts\test\log.txt"
Rename-Item -Path "D:\Mitek\DCS Stuff\Display PC Scripts\test\RemoteComplete.bat" -NewName "Remote.bat"
Exit
} Else {
if ($Target -ne $null){
Compare-Object $Source $Target -Property Name -PassThru | Where-Object {$_.SideIndicator -eq "=>"} | % {
if(-not $_.FullName.PSIsContainer) {
Write-Output "Removed From $Local" | timestamp | Out-File -Encoding Ascii -append "D:\Mitek\DCS Stuff\Display PC Scripts\test\log.txt"
Remove-Item -Path $_.FullName -Force -ErrorAction SilentlyContinue}}}}
$Differences = Compare-Object -ReferenceObject $Source -DifferenceObject $Target -Property LastWriteTime -PassThru
$Differences | Group-Object Name | Select -ExpandProperty Group | Sort-Object LastWriteTime | Select-Object -Last 1
if ($Differences -ne $null) {
foreach ($file in $Differences) {
#Copy-Item -Path $Differences -Destination $Local –Force
Start-BitsTransfer -Source $Differences -Destination $Local
Write-Output "Copied to $Local" | timestamp | Out-File -Encoding Ascii -append "D:\Mitek\DCS Stuff\Display PC Scripts\test\log.txt"
Rename-Item -Path "D:\Mitek\DCS Stuff\Display PC Scripts\test\RemoteComplete.bat" -NewName "Remote.bat"}
} Else {
Write-Output "$Local and $Remote are Equal" | timestamp | Out-File -Encoding Ascii -append "D:\Mitek\DCS Stuff\Display PC Scripts\test\log.txt"}`
I got the issue figured out with some looping behavior the code used to resolve the issue is bellow for those who may find this helpful in the future...
$Local = 'C:\test\local\'
$Remote = 'C:\test\server\'
$Target = Get-ChildItem -Path $Local -File
$Source = Get-ChildItem -Path $Remote -File
$One = 1
Set-Location $Remote
filter timestamp {"$(Get-Date -Format g): $_"}
if ($Target -eq $null) {
$TotalA = $Source | Measure | Select-Object -ExpandProperty Count
echo "Total Number of Files to be Copied= $TotalA"
echo "---------------------------------------------------------------"
Write-Output "$Local Folder Empty" | timestamp | Out-File -Encoding Ascii -append "D:\Mitek\DCS Stuff\Display PC Scripts\test\log.txt"
Start-BitsTransfer -Source $Remote\*.* -Destination $Local -Description "Copying $TotalA Files"
Rename-Item -Path "C:\test\RemoteComplete.bat" -NewName "Remote.bat"
exit
} Else {
if ($Target -ne $null){
Compare-Object $Source $Target -Property Name -PassThru | Where-Object {$_.SideIndicator -eq "=>"} | % {
if(-not $_.FullName.PSIsContainer) {
Write-Output "Removed From $Local" | timestamp | Out-File -Encoding Ascii -append "D:\Mitek\DCS Stuff\Display PC Scripts\test\log.txt"
Remove-Item -Path $_.FullName -Force -ErrorAction SilentlyContinue}}}}
$Differences = Compare-Object -ReferenceObject $Source -DifferenceObject $Target -Property LastWriteTime -PassThru
if ($Differences -ne $null) {
$TotalB=$Differences | Group-Object Name | Select -ExpandProperty Group | Sort-Object Name | Measure | Select-Object -ExpandProperty Count
echo "Total Number of Files to be Copied= $TotalB"
Write-Output "Copied to $Local" | timestamp | Out-File -Encoding Ascii -append "D:\Mitek\DCS Stuff\Display PC Scripts\test\log.txt"
do {
$Tar = Get-ChildItem -Path $Local -File
$Src = Get-ChildItem -Path $Remote -File
$Diffs = Compare-Object -ReferenceObject $Src -DifferenceObject $Tar -Property LastWriteTime -PassThru
$ListB=$Diffs | Group-Object Name | Select -ExpandProperty Group | Sort-Object Name | Select-Object -First 1
if ($ListB -ne $null) {
echo "---------------------------------------------------------------"
$Rmn=$Diffs | Group-Object Name | Select -ExpandProperty Group | Sort-Object Name | Measure | Select-Object -ExpandProperty Count
$RemainB = $Rmn - $One
Start-BitsTransfer -Source $ListB -Destination $Local -Description "$RemainB Files Remain Copying - $List" }}
Until ($ListB -eq $null)
Rename-Item -Path "C:\test\RemoteComplete.bat" -NewName "Remote.bat"
} Else {
Write-Output "$Local and $Remote are Equal" | timestamp | Out-File -Encoding Ascii -append "D:\Mitek\DCS Stuff\Display PC Scripts\test\log.txt"}
