No. Storing files in the webserver folder so that you can serve them back up is not supported and cannot be supported for dynamic content. This is one of the reasons. (It is fine for static content, but is not guaranteed to keep working in future Ignition versions.)
Use the WebDev module if you need to serve actual files to Perspective clients. Use something like my Blob Server module if you can use database blobs instead of files.
(I changed the category for you. It is an Ignition question, not a general discussion question. Please choose a proper category if want the right eyes to see your questions.)
