<\/figure><\/div>\n\n\n\nIf you’re using Arduino IDE follow this tutorial instead: Install ESP32 Filesystem Uploader in Arduino IDE<\/a>.<\/p>\n\n\n\n The ESP32 contains a Serial Peripheral Interface Flash File System (SPIFFS). SPIFFS is a lightweight filesystem created for microcontrollers with a flash chip, which are connected by SPI bus, like the ESP32 flash memory.<\/p>\n\n\n\n SPIFFS lets you access the flash memory like you would do in a normal filesystem in your computer, but simpler and more limited. You can read, write, close, and delete files. SPIFFS doesn\u2019t support directories, so everything is saved on a flat structure.<\/p>\n\n\n\n Using SPIFFS with the ESP32 board<\/a> is specially useful to:<\/p>\n\n\n\n The files you want to upload to the ESP32 filesystem should be placed in a folder called data<\/em> under the project folder. For you to understand how everything works, we’ll upload a .txt<\/span> file with some random text. You can upload any other file type.<\/p>\n\n\n\n If you’re not familiar with VS Code + PlatformIO, follow the next tutorial first:<\/p>\n\n\n\n Create a folder called data <\/em>inside your project folder. This can be done on VS Code. This new folder must be called data<\/em>, otherwise, it won\u2019t work.<\/p>\n\n\n\n Then, select the newly created data <\/em>folder and create the files you want to upload by clicking on the New File<\/strong> icon. In this example, we’ll create a file called text.txt<\/span>. You can create and upload any other file types like .html<\/em>, .css<\/em> or .js<\/em> files, for example.<\/p>\n\n\n\n Write some random text inside that .txt<\/span> file.<\/p>\n\n\n\n The data <\/em>folder should be under the project folder and the files you want to upload should be inside the data <\/em>folder. Otherwise, it won’t work.<\/p>\n\n\n\n After creating and saving the file or files you want to upload under the data<\/em> folder, follow the next steps:<\/p>\n\n\n\n Important: <\/strong> to upload the filesystem image successfully you must close all serial After a while, you should get a success message.<\/p>\n\n\n\n Here’s some common mistakes:<\/p>\n\n\n\n This error means that you have a serial connection opened with your board in VS Code or in any other program. Close any program that might be using the board serial port, and make sure you close all serial connections in VS Code (click on the recycle bin icon on the terminal console).<\/p>\n\n\n\n If you start seeing a lot of dots on the debugging window and the filesystem image fails to upload, you need to press the on-board boot button once you start seeing the dots.<\/p>\n\n\n\n To solve this issue permanently, read the following article: <\/p>\n\n\n\n Now, let\u2019s just check if the file was actually saved into the ESP32 filesystem. Copy the following code to the main.cpp<\/span> file and upload it to your board.<\/p>\n\n\n View raw code<\/a><\/p>\n\n\n\n You may need to change the following line depending on the name of your file.<\/p>\n\n\n\n Open the Serial Monitor and it should print the content of your file.<\/p>\n\n\n\n You’ve successfully uploaded files to the ESP32 filesystem (SPIFFS) using VS Code + PlatformIO.<\/p>\n\n\n\n With this tutorial you’ve learned how to upload files to the ESP32 filesystem (SPIFFS) using VS Code + PlatformIO. It is quick and easy.<\/p>\n\n\n\n This can be specially useful to upload HTML, CSS and JavaScript files to build web server projects with the ESP32 boards.<\/p>\n\n\n\n We have a similar tutorial for the ESP8266 NodeMCU: ESP8266 NodeMCU with VS Code and PlatformIO: Upload Files to Filesystem (LittleFS)<\/a><\/p>\n\n\n\n Learn more about the ESP32 with our resources:<\/p>\n\n\n\n Learn how to upload files to the ESP32 board filesystem (SPIFFS) using VS Code with the PlatformIO IDE extension (quick and easy).
