Is it possible OTA modules folder ?

[McFly589]

Hi !
I did a project using Pico W and Micro-python. When project was growing and growing I start to get memory errors so finally, I copied almost all files under modules folder and created a firmware.uf2 file.
Now, I would like to add OTA (update files Over The Air). Is it possible update directly from Pico ? I can't even find if it's possible to access to modules folder...

Thanks !
