Do you need to upload large files to FTP from your ESP32 (images, videos or any other files from the SD Card?). Here we show how this can be easily achieved, with virtually any file format! More information and links below...

Continuing on from our previous video about FTP Uploads, a number of people asked how to transfer larger files, or files which are not text files, so here is the walkthrough to show how this can be done.

There are minimal changes to include the SD Library, and with our added function to send the File chunk by chunk to the FTP server, you can send a file of virtually any size....

Try changing the buffer size, and different file sizes on the SD card to see how it affects performance....
