Raspberry Pi pico can not download other programs

I have a question, I copied the program into Raspberry Pi pico when I was working on the project of thermal printer parking system, after that I tried to copy other programs but they failed, is it because the pico board can only copy one program?

The "pico" supports several languages: C++, Javascript, MicroPython & Circuit Python, Arduino, etc. The specific methodology is aligned to the language. For example, the Pico is a "virtual USB" storage device for MicroPython/CircuitPython ... just drag-n-drop! For C++, the "binary" is loaded as a single file. For Arduino, the IDE does the magic (at least with https://github.com/earlephilhower/arduino-pico )

The RP2040 is a most interesting uC at the $4 price point. I still gravitate to the ESP32 mainly for flexibility and maturity ... RF can be disabled and sacrificed when not needed. I particularly find SPIFFS fun and useful ... even on an ESP8266, the ENTIRE MAC to OUI database in ASCII can be housed in the external storage! https://mac2vendor.com/
