Now you can update your files in /http directory of your tiny webserver over Wi-Fi! Drag&drop or browse one or multiple files. List uploaded files. Delete files. Automatically rename files to http/(filename) Automatically compile .lua files. Shows total/used memory. You must compile upload.lua file! Have some bugs but works pretty well even for uploading lot of files.
