The command "pio system prune --cache" is used to clean and remove unnecessary cached files and directories created by the PlatformIO tool.
When running PlatformIO, it creates a cache directory to store various data like package downloads, build artifacts, and other temporary files. Over time, this cache can consume a significant amount of storage space on your computer.
By executing the "pio system prune --cache" command, you initiate a cleaning process which removes unused or outdated files from the cache directory. This operation helps free up disk space, improve performance, and ensure you have the latest and necessary files for your projects.
It is important to note that pruning the cache may require downloading certain files and packages next time you build a project, so it might take a little longer for the first build after pruning.
