How to create destination folder with date appended to it via Powershell? - windows

Question

I have backup files sitting in a directory. The objective I am trying to achieve is that each time I run this piece of Powershell against that directory, I want it to move the files into a folder that gets created and append today's date to it. I have tried this:
Get-ChildItem -Path 'C:\API\APIBackups' | ForEach-Object {
Move-Item -Path $_.FullName -Destination "C:\Users\Admin\Desktop\New folder\$($_.BaseName,(Get-Date).ToString("MMddyyyy"),$_.Extension)"
}
All this does is moves the backup files into "New folder" and append the date to the files themselves. I'm wanting it to create a new folder with today's date appended within "New folder" and have the backup files sitting in there. Any help would be great.

For one the commas do not belong but each section of "code" needs their own subexpression. You are also sticking the date in between the base filename and the file extension, so it looks like you want to insert the date in the file name. Instead, you can adjust it to this.
Get-ChildItem -Path 'C:\API\APIBackups' | ForEach-Object {
Move-Item -Path $_.FullName -Destination "C:\Users\Admin\Desktop\New folder$((Get-Date).ToString("MMddyyyy"))\"
}
Unless you're renaming the file, you don't need to specify it in the path.
Important Note that if that folder does not exist, you will need to create it first. Otherwise you'll end up with an extensionless file with that name instead. You could test for the path first, create if it doesn't exist, then move.
Get-ChildItem -Path 'C:\API\APIBackups' | ForEach-Object {
$newfolder = "C:\Users\Admin\Desktop\New folder$((Get-Date).ToString("MMddyyyy"))\"
if(-not(Test-Path $newfolder)){
$null = New-Item -Path $newfolder -ItemType Directory
}
Move-Item -Path $_.FullName -Destination $newfolder
}
The $null is to hide the output that New-Item creates by default.
A suggestion for improvement would be to use Join-Path for building the new folder path
