Yet another, arduous powershell question

$computers = Get-content 'C:\Powershell Projects\lastconnect\New Text Document.txt'
Foreach ($computer in $computers)
 {Copy-Item -Path '\\$Computer\Program Files (x86)\Quest Software\Toad for Oracle 10.5\ClientFiles\QSAuth11.key' -Destination 'c:\programs\powershell projects\$computer.txt'}

So the script above, I know I can't put the variable in like that, but I can't find or figure out how to get it to work the way I need it to.

Could you help at all?

You can use variables like that, but you need double quotes around the string. A string in single quotes will be used verbatim by Powershell.
And though it's not required here since it's a plain vanilla variable (and not a property of an object), I prefer to put all variables appearing in strings consistently inside subexpressions:
$Computers = Get-content 'C:\Powershell Projects\lastconnect\New Text Document.txt'
ForEach ($Computer in $Computers) {
	Copy-Item -Path "\\$($Computer)\Program Files (x86)\Quest Software\Toad for Oracle 10.5\ClientFiles\QSAuth11.key" -Destination "C:\programs\powershell projects\$($Computer).txt"

Ahhhhh you're back!!!!

So it was the $ at the start and the double quotes..

I even put double quotes in to start but then thought I'd go with the single quotes.... Woe is me :(


I'm up to this now

$Computers = Get-content 'C:\Powershell Projects\audit\computers.txt'
ForEach ($Computer in $Computers){
    If (test-connection -computername $Computer -quiet) 
	Copy-Item -Path "\\$($Computer)\c$\Program Files (x86)\Quest Software\Toad for Oracle 10.5\ClientFiles\QSAuth11.key" -Destination "C:\powershell projects\$($Computer).txt"

Else { 
        "$($computer) is not online" | Out-File -Append "C:\Powershell Projects\\computersnotonline.txt"

Note: It would have been sufficient to use "\\$Computer\c$\...", but that only works if parsing allows for clear detection where the variable name ends. "\\${Computer}\c$\..." is more safe, but then it is not far from generally using "$($Computer)\c$\...", which technically uses a subexpression ( $(...) is a subexpression, allowing for expressions).
