Each Project you create in the EV3 Software is made up of a number of smaller files (images, sounds, and so on). Stored within each Project file may be one or more programs, along with images, sounds, text files, and/or raw data log files.

Tips and Tricks

All files are stored within the Project file. If you want to access an individual file, use the Project Properties Page to upload them to your computer.

Applications

Projects can be converted into applications and transferred to the Brick Apps folder of the EV3 Brick. Once converted, the programming blocks of an Application can no longer be edited. Applications can be deleted via the Memory Browser. Select Download as App from the Tools menu to convert and download your Application to the EV3 Brick.

On Brick Memory

Each EV3 Brick has an available memory of about 16 Megabytes. Some of this memory is used to store the example programs, graphics, and sound files that are pre-loaded on the EV3 Brick. This leaves about 6 Megabytes for the files you create and download.

If you want to free up more memory space, you can delete the example programs. See Memory Browser for details on how to remove files.

Updating the EV3 Firmware will restore all files on the EV3 Brick to the factory default condition.

SD Storage Card

Extra storage space is available using the built-in SD Card Port.

The EV3 Brick accepts SD storage cards up to a maximum capacity of 32GB.

Managing and transferring files on the EV3 Brick

It is sometimes necessary to manage files and memory on the EV3 Brick. You can do this using the Memory Browser.

Detailed information about how to move, delete, and import files can be found in Memory Browser.
