Powershell Script to copy file to new folder

If you are looking to keep with those 2 lines of code you need to wrap the Get-Date portion in $(). This tells PS to resolve that code before using the string inside the double quotes.

So your code would look like this:

New-Item -Path "c:\users\random\desktop\$((Get-Date).ToString('yyyy-MM-dd'))" -ItemType Directory
copy-item c:\users\random\desktop\rand.txt "c:\users\random\desktop\$((Get-Date).ToString('yyyy-MM-dd'))"

However, you could have one flaw if your script is ever executed within microseconds of midnight: Each command would get a separate date.

A better method to use is to simply grab the date in a variable and use that in both of your commands. It will also make it more readable:

$cDate = Get-Date -format yyyy-MM-dd
$NewPath = "C:\Users\random\desktop\$cDate"
New-Item -Path $NewPath -ItemType Directory
Copy-Item c:\users\random\desktop\rand.txt $NewPath

This would ensure you get the same date value if you happen to pass midnight when it runs. Although, that is probably not going to be an issue it doesn't hurt to be safe.

you miss a dollar sign before the bracket

"c:\users\random\desktop**$**((Get-Date).ToString('yyyy-MM-dd'))"

Create a variable to store your GetDate, then convert it in to a string.

$currentdate = date $currentdate2 = $currentdate.ToString("yyyy-MM-dd")

Hence your code folder path will be 'c:\users\random\desktop\$currentdate2'
