ESP32, SD and WiFi - Download/Upload/Delete SD files using ESP32 microcontroller as a web server
This videos shows how to download and upload data from a SD card connected to an ESP32 microcontroller board using its wifi capabilities. For this we will generate a soft access point and a webserver to access the files, allowing to manage the information inside the SD card without the need of unplugging it. Imaging the possibilities!

Wow! Great content, but need to slow down. I had to playback and 75% speed. Just constructive feedback. English is spoken slower. Again, love the content.
Really wonderful project....Your are really great....Clear explanation...Perfect flow...do more of these videos...Keep rocking
I download the first exemple and just change SD CD pin to adapta to my configuration and.........just work great!!!! thanks a lot

I would like to use the sample with ESP32 S2. I don't need a sensor or deepsleep. But I can not open the mcserver although it is connected.
can esp32 sends file from sd card to https server?
This is exactly what I’m looking for. I’m not yet sure how to implement it, but I have an M5Paper e-ink device ran by an ESP32. I’ve been looking for a way to manage files on the built in SD card over wifi so I don’t have to pop it in and out.
I have theh 30-pin esp32, and I cant find where to change the pin assignment to modify with respect to my setup. Please help.
Hello, at what speed are you able to download the files? Is it suitable for big filesizes > 500MB? Great Video and thanks already.

I tested it.. works really good but not for files that are big.. like MP3 or MP4 and etc... because the peak of its speed is 34 KBPS
Hello sir, your project works really well except for the download and upload speed limitation. Is there any way to increase the upload speed. Currently I am able to get upto 48KBytes/s upload speed and 50KBytes/s download speed. If you have any solution please let me know. Thank you

Hi, that problem should be related with the connection of the SD board to the microcontroller, SD pin number in the code, or pull up resistors. You can send me a Pic of the hardware to my email. Best!

Excelente vídeo. ¿Cómo puedo acceder a los directorios o carpetas?
i like you bro
does this videos shows data logging in sd card and then esp32 act as datalogger also user can access the logged files using accesspoint and user can download the sd card logged files to remote pc..

Hello, I have used the code you have provided and modified the CSS a little to make it look a little nicer, this is amazing, however, I would really appreciate it if you could add a function to rename the files on the webpage, maybe double click the file name and a text box appears? I would also appreciate it if you could help me fix my CSS, as there is 1 minor issue, please let me know the best way to send you my files, thanks!

Hello! We are from Ukraine. Is it possible to make an mp3 player based on the esp 32 cam chip? It is necessary to implement access to the sd to delete and add mp3 files. It is very necessary to implement. Thanks for the tips !
