Summary

This is web based app that you simply need to copy on the Toshiba FlashAir wireless SD card to enable remote upload and deleting of files. With this I don't need to take the SD card on the printer and use my computer browser to drag and drop files that I need to print.
I just added some dummy STL so I can make it available to the public.

Instructions

Backup all your files first. I'm not responsible if someting goes wrong on your SD card content.

Follow Toshiba FlashAir instruction to setup you SD card to Station Mode.

Unzip the package to the root of the SD card. The package has all the files it needed to run the web app. I removed CONFIG on the package as this file is specific to your SD card settings.

You might need to adjust your explorer settings to shows hidden folders for a while.

If you don't have any folder on your SD card, you need to create atleast one. Hidden folder does not count. I created folder name "Queue" but any name will do.

Now using any browser visit the your SD card using http://{SD_APPNAME_or_IPAddress}/{folder}. ex: http://3DPrinter/Queue

From here you can drag and drop files and delete existing files.
