Thanks for your time to reply! My JS manages documents. When the user adds a new document my JS must upload that {file}from the user’s “disk”, the {source}, into one of the “public-html/Docs/xxx/” folders, the {target}. My script knows the {file} and {target} names. The user supplies the {source} directory name. Could you please publish or email an “upload.html”, a fully working example which uploads {file} from {source} to {target}?
