1. The Bootrom of RP2040 provides a standard USB boot loader, which can be recognized as a writable drive for using UF2 files to copy code to the RP2040. The UF2 file copied to the drive is downloaded and written to Flash or RAM, and the device is automatically restarted, allowing code to be downloaded and run on the RP2040 solely via USB connection. | 1.

2. Any type of file can be written from the host to a USB drive, but these files are typically not stored; it appears so only due to the host's cache. Only when a UF2 file is written to the device, special content is recognized, and data is written to a designated position in RAM or Flash. After downloading the complete and valid UF2 file, the RP2040 will automatically reboot to run the newly downloaded code. | 2.

3. UF2 files will not be stored, but instead, the firmware is flashed to the specified location according to the corresponding file format, the specific file format can refer to Microsoft's open source project at [https://github.com/microsoft/uf2] | 3.
