I'am working on displaying files in my dashboard. So, is there anyway to add the location start folder dynamically.
for exemple, can'i set the a msg.foldername then send it to fs-file-lister node??
i have read the node help and i don't think it is possible ....

I found that "fs-ops-dir" does this.
