Hi all,

I have a variable called $accepted which contains a list of files I want to move, the below code works if the files exist and get stored but if no files are found making $accepted empty I get a error. I want the script to do something if the files exist but if its empty, write no files found. I cant understand why this doesnt work.

if ($accepted -eq $null) {write No Files found}
else {Move-Item $accepted e:\Team_Upload\}

The items get moved if they exist but if not I get the error

Move-Item : Cannot bind argument to parameter 'Path' because it is an empty array.
ERROR: At line:74 char:16
ERROR: + else {Move-Item <<<< $accepted e:\Team_Upload\}
ERROR: Get-ChildItem : An object at the specified path E:\ does not exist.

Could you post all of your code? How is $accepted created?

Because $accepted is an array, you could check $accepted.count. There is also an operator -contains which you can use to see if a specific item exists in the array.
