Powershell - Script not entering for each loop - shell

Question

I have a script set to enter a for each loop every-time a file is created. Once in the loop it will move a file to a another folder and if the same file has to be moved 3 times it will move the file to a different table and remove the record of it from the hash table.
My issue is when I run the script it does not do anything that I write inside the for each loop. Only if I write script above it. Can someone please advise?
$folder = 'C:\Users\jnwankwo\Documents\IUR Test\r' # Enter the root path you want to monitor.
$Failedfolder = 'C:\Users\jnwankwo\Documents\IUR Test\r'
$filter = '*.*' # You can enter a wildcard filter here.
$Files = #{}
$Counter = 1
$folder = 'C:\Users\jnwankwo\Documents\IUR Test\r' # Enter the root path you want to monitor.
$Failedfolder = 'C:\Users\jnwankwo\Documents\IUR Test\r'
$filter = '*.*' # You can enter a wildcard filter here.
$Files = #{}
$Counter = 1
# In the following line, you can change 'IncludeSubdirectories to $true if required.
$fsw = New-Object IO.FileSystemWatcher $folder, $filter -Property #{IncludeSubdirectories = $false;NotifyFilter = [IO.NotifyFilters]'FileName, LastWrite'}
Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated -Action {
ForEach ($file in $folder)
{
$fName = $file.Name
if (-not $Files.ContainsKey($fName))
{
$Files.Add($fName,$Counter)
}
if (($Files.ContainsKey($fName)) -and ($Files.Item($fName) -lt 3))
{
Move-Item 'C:\Users\jnwankwo\Documents\IUR Test\r\*.txt' 'C:\Users\jnwankwo\Documents\IUR Test' -force
$Files.Set_Item($fName,$Counter++)
}
ElseIf (($Files.ContainsKey($fName)) -and ($Files.Item($fName) -eq 3))
{
$Files.clear()
Move-Item 'C:\Users\jnwankwo\Documents\Failed\' $Failedfolder -force
}
}
}
# To stop the monitoring, run the following commands:
# Unregister-Event FileCreated

Answer 1

I have found one thing in your code.
Change ForEach ($file in $folder) to ForEach ($file in (gci $folder))

Answer 2

Here you go, you will have to change the folders back though :)
$folder = 'C:\temp\test' # Enter the root path you want to monitor.
$filter = '*.*' # You can enter a wildcard filter here.
# In the following line, you can change 'IncludeSubdirectories to $true if required.
$fsw = New-Object IO.FileSystemWatcher $folder, $filter -Property #{IncludeSubdirectories = $false;NotifyFilter = [IO.NotifyFilters]'FileName,LastWrite'}
Register-ObjectEvent $fsw Created -SourceIdentifier FileCreated -Action {
$folder = 'C:\temp\test' # Enter the root path you want to monitor.
$Failedfolder = 'C:\temp\test3'
$Files = #{}
$Counter = 1
ForEach ($file in (gci $folder))
{
$fName = $file.Name
if (-not $Files.ContainsKey($fName))
{
$Files.Add($fName,$Counter)
}
if (($Files.ContainsKey($fName)) -and ($Files.Item($fName) -lt 3))
{
Move-Item $file.Fullname 'C:\Users\jnwankwo\Documents\IUR Test' -force
$Files.Item($fName) = $Counter++
}
ElseIf (($Files.ContainsKey($fName)) -and ($Files.Item($fName) -eq 3))
{
$Files.clear()
Move-Item $file.Fullname $Failedfolder -force
}
}
}
Addition:
To store your Hashtable to a file and re-import it on the next run you can use the following code:
#store hashtable to file
$Files.GetEnumerator() | % { "$($_.Name)=$($_.Value)" } | Out-File files_ht.txt
#to import again
$Files = Get-Content files_ht.txt | Convertfrom-StringData
This should enable you to have the data from the hashtable persistent
