List files details from folders and subfolders are duplicading - powershell

Question

I'm trying to get the names of the files within the directory and the sub directories within the "parent" directory.
I managed to solve my problem in parts, but in the last directory it is multiplying the files (as if I was checking this folder twice).
If I have 2 items, he is exporting me 4 to that last directory.
I managed to get the files from the directories, but if I have any files in the root directory (parent directory), it won't list.
Parent dir "\XML"
File1.xlsx
File2.txt
Folder2
Dir "Folder2"
File1.xml
File2.xml
So, in the CSV file exported will be 4 rows, which is duplicate files from "Folder2" folder. And it won't bring me the files in the "XML" folder, which is the parent folder.
Powershell script:
# To execute the script without agreeing with the execution policy
Set-ExecutionPolicy Bypass -Scope Process
# Defines the parent directory, where all files and folders inside it will be
$DirPai = 'D:\Users\F02579\Desktop\XML'
# Variable to store all directories within the parent directory
$DirPastas = (Get-ChildItem -Directory -Recurse $DirPai).FullName
# Variable that will keep the final result
$results = #()
foreach ($Dir in $DirPastas)
{
# Write the directory name
Write-Host $Dir
# Get the file details
$Arquivos = Get-ChildItem -Path $Dir -Recurse | Select-Object Directory, Name, Lenght, LastWriteTime, #{Name="Extension";Expression={$_.Extension}} #| Where-Object "Extension"-ne ''
# Store the result for each path
$results += $Arquivos
}
# Defines the directory to which the final file will be exported
$DiretorioExportacao = 'D:\Users\F02579\Desktop\XML\I_PI_LISTFILES.csv'
# Export the result to CSV in the previously informed directory
$results | Export-Csv -Path $DiretorioExportacao -NoTypeInformation -Encoding UTF8

Answer 1

You could reduce your code to the following.
Keep only the first Get_ChildItem. Remove the -Dir switch (ie. get files and folders)
Pipe directly to Select-Object. Don't bother with an explicit loop.
This will give a result with five items: four files and one folder.
You also had a typo with 'length'.

Answer 2

You already have all the directories captured so in your loop you need to specify the -File parameter and there is no need for the -Recurse parmaeter.
$Arquivos = Get-ChildItem -Path $Dir -File |
Select-Object #{Name="Directory",Expression($Dir),
Name, Lenght, LastWriteTime,
#{Name="Extension";Expression={$_.Extension}}
