Then don't use it.
$sfDesktop = [Environment]::GetFolderPath("Desktop")
If( $sfDesktop )
{
If( test-path $sfDesktop )
{
"it's all good, call the function "
}
}

Yeah,
You have to pardon my lack of ps experience:)
I really don't know what happens to that var if the expression bails, so
"whatever" the contents of the var after failure are, I didn't want to push
that into the backup function.
Thanks Rubens and Michael!

Test-path is probably what you want. I'm not sure what you mean by "enumerate
correctly".

Hey Rubens,
I am not too concerned with how I get the value, but more on how to trap if it
doesn't enumerate correctly.
Once I start looping through all the special folders of interest, I don't want
to send something wrong into the routine that follows.
Thanks!

I'd try something like this:
$sfDesktop = $env:USERPROFILE + "\desktop"
