I would like to know how do I import a .mp3 and use it in the mobile project

Good Morning,
To use a .mp3 just import it in resources

Then create a screen and use interaction\video and pass sourceFile



Doe best practice put big size resources in a separate module with public property true.

MP3 or video resources take a lot of space.

Putting them in a module where you also code, on every 1 click publish you store a copy of your resources in OutSystems version control system. This takes a lot of space when you change your module frequently and also slows down the one click publish time.

Putting it in a separate module that has thus a much less update frequency will fix those problems.
