Re: Flowscript - delete file

Solved

I found the answer at 
http://markmail.org/message/7psype56uhu5kbad#query:+page:1+mid:ezqkl6i255bjdw75+state:results

I amended file.delete(); to:

file["delete"]();

and it works,  the file is deleted. However, I don't know why it works

Thank you all for your help

Peter
