Determine file extension before running power shell script

[Anonymous]

I have created a power shell script but I need to check the selected file extension and only allow it to run on IPT or IAM files.  How can I get the extension and exit the script if it is the wrong type?

Thanks for any assistance.

Hi Mike,

Is it DataStandard that you are asking about? If it is, then in the powershell you can use one of the system variables called _FileExt in the $Prop[] array. 

if ($Prop["_FileExt"].Value -eq "IAM" -or $Prop["_FileExt"].Value -eq "IPT" )
{
    #your code here
}
else
{
    #exit script or messagebox etc.
}
